In line with the Swedish government’s vision that Sweden should be climate neutral by 2050, public transport company Västtrafik expects to have electrified all city traffic in Västra Götaland by 2030. Volvo Buses and ABB are helping to realize that aim with the supply of 157 new electric buses and supporting charging infrastructure to bus operator Transdev.

Starting in 2020, 157 new Volvo electric buses will start operating on the streets of Gothenburg, Mölndal and Partille, powered by charging infrastructure solutions from market leading provider, ABB. This landmark announcement represents an important step towards achieving a sustainable public transport solution for the 180 million trips made by bus in the region each year.

With services scheduled to commence in December 2020, the new electrified lines will mean a total of 220 electric buses to transport Gothenburg’s residents and visitors by the end of the year.

19 new high-power electric chargers will be installed during the second half of 2020 before the new buses go into operation, and another two stations are planned for the future.

The buses in Gothenburg, Mölndal and Partille will be charged by 450 kW high power Panto Down chargers from ABB. A modular solution based on OppCharge, an open interface for direct current (DC) electric bus charging, the solution offers high-power charging via an automated rooftop connection. ABB will supply a complete solution that includes both the charging stations and all the necessary grid connection hardware via ABB’s cable distribution cabinets.

The buses will be recharged in just three to six minutes at charging stations along the routes. The high-power chargers, a part of ABB’s innovative ABB Ability™ offering of digital solutions and services across all business areas, delivers web-enabled connectivity that allows network operators to perform remote monitoring and configuration of charge points and also minimizes downtime and increases efficiency.

With room for 150 passengers and an 88 percent reduction in CO2 when transitioning to electricity, the new buses combine high passenger capacity with low environmental footprint.

ABB has won a contract from ST Engineering Land Systems Ltd. to deliver and com-mission integrated smart charging points for Automated Guided Vehicles (AGV) in the new Tuas port of Singapore. Deliveries of the vehicles, which will be deployed to transport heavy shipping containers at the port terminal, are scheduled to begin from September 2020 through to August 2022, with the ABB chargers and supporting infra-structure set to be installed towards the end of 2020.

The contract includes 450 kW High Power Chargers, design and supply of charge point prefabricated skid and container solutions with integrated chargers, medium- and low- voltage switchgear, transformers and associated control and monitoring equipment. This integrated solution enables fast installation on site, ensures the highest levels of operability and mitigates risk.

The future port is a major milestone in Singapore’s next generation container terminal development with an annual capacity of 65 M containers (TEU) and is slated to be the largest port in the world by the time it is complete in 2040. The first berth will be op-erational in 2021.

The breakthrough project marks the first time ABB’s chargers will be used to power a fleet of autonomous vehicles for commercial operation. A specially designed and cus-tomized connection to the chargers will be enabled for end-to-end integration with the fully-electric AGVs.

CMBlu Energy and Mann+Hummel have signed an agreement for the joint development and industrialization of energy converters for organic redox flow batteries. The aim of both partners is to support electric mobility through the development of the charging infrastructure and offer the energy sector a sustainable and highly cost-efficient storage technology for a successful energy transition.

From the idea to the laboratory, then series production

The business idea for redox flow batteries with organic electrolytes derived from lignin (‘Organic Flow’) was already conceived in 2011 and since 2014, CMBlu has carried out intensive research and development. These batteries essentially consist of two tanks of liquid electrolyte and an energy converter, which consists of a large number of adjacent rows of cells and is therefore also referred to as a battery stack. The liquids are pumped through the battery stacks and is charged or discharged as required.

The technology developed by CMBlu has now reached the prototype stage. The further development and industrialization of the battery stack is regulated in the long-term cooperation agreement with Mann+Hummel. For this purpose Mann+Hummel has created a spin-off named i2M, which is dedicated to the development and commercialization of innovative technologies. In the next step Mann+Hummel will build a complete production line in an European plant. CMBlu will realize special pilot projects with reference customers in the next two years. Starting in 2021, CMBlu plans to market the first commercial systems.

Benefits of organic flow batteries

Similar to the principle of conventional redox flow batteries, CMBlu’s organic flow batteries store electrical energy in aqueous solutions of organic chemical compounds derived from lignin that are pumped through the energy converter, i.e. battery stack. The special feature of the flow batteries is that the capacity and electrical output can be scaled independently. The number of stacks defines the output of the batteries. A higher number of stacks multiplies the output. The capacity of the battery is only limited by the size of the tanks. This allows flexible customization to take into account the respective application area. For example, solar power can be stored for several hours and then fed into the grid at night.

In order to achieve cost-effective mass production, the most important components in the stack were adjusted to the organic electrolyte. In this process, almost the entire value chain for the stacks can be supplied locally. There is no dependency on imports from other countries. In addition, the battery stacks do not require rare-earth metals or heavy metals. The aqueous electrolytes in the system are not combustible or explosive and can be used safely.

Variety of applications in the grid

Organic flow batteries are suitable for numerous application areas in the power grid such as the intermediate storage of power from renewable energy generation or in connection with the balancing of demand peaks in industrial companies. An additional application area is the charging infrastructure required for electric mobility. The batteries enable a buffer storage to relieve power grids which do not have to be upgraded for additional loads. It enables simultaneous fast charging of electric vehicles. Ultimately, a decentralized charging network for electric vehicles will only be possible in connection with a high performance and scalable energy storage system.

Nature as a model for energy storage

The concept is based on the mode of energy in the human body. In the citric acid cycle the body also uses a redox reaction of organic molecules. CMBlu has now succeeded in applying this principle to large-scale storage of electrical energy. For this purpose the company use the mostly unused resource of lignin, which is readily available in unlimited quantities and accrues in amounts of millions of tons annually in the pulp and paper industry. CMBlu’s technology enables a very large and cost effective energy storage system. The battery stack is the core of the system and requires the highest quality and process reliability in the production process.

The manufacture of electrolytes includes a number of filtration steps, which Mann+Hummel performs using new special membranes. This technology further expands its product range and at the same time contributes to build the infractruture needed for electric vehicles.

Manufacturers and suppliers of charging infrastructure, will be presenting their innovative product portfolios at Hannover Messe. One such company is Mennekes Elektrotechnik GmbH & Co. KG, based in the Sauerland region: “2019 is going to be a very exciting year for us,” says Alfred Vrieling, head of sales at Mennekes.“The American car maker Tesla will be launching its Model 3 on the German market, and we’ll see what happens then.” Vrieling is optimistic about the future, as he contemplates the mobility revolution that is just around the corner: “When electromobility really takes off, we’ll definitely be part of it.” As well as the domestic market, the technology company from Siegen has the whole of Europe in its sights, with Norway, Switzerland, Sweden and the Netherlands currently doing the most to promote electromobility.

But market growth depends on continuing expansion of the infrastructure. As well as developing suitable plugs and connectors, Mennekes has been concentrating for years on the installation and servicing of charging points. “You only make a journey in an electric car if you know it is easy to recharge the battery when you reach your destination,” says Vrieling, who drives an electric car himself, and therefore knows what he is talking about. “Before people will really embrace electric-powered travel, we need to build confidence and ensure greater continuity and availability.” And what we also need as a matter of urgency, argues Vrieling, are “fixed tariffs agreed between providers and operators of charging points.” As he goes on to point out, this will require some form of government legislation to avoid chaos in the future.

Talking of government involvement: the National Platform for Electromobility (NPE) has calculated that we will need 70,000 public charging points and 7,100 fast charging points in Germany by 2020. The Federal government has allocated 300 M€ of funding up until the year 2020 for the expansion of the public charging network to meet growing demand. What is still uncertain is how today’s power grid is going to cope with the rising demand, and how the necessary infrastructure can be made available both in major conurbations and in rural areas.

Once power grids been fully digitized, industry insiders are confident that the market for electromobility will grow rapidly. There is already a demand for intelligent technologies of the kind that firms such as ABB and Phoenix Contact GmbH & Co. KG will be displaying at the upcoming Hannover Messe in April. As more parking space is needed for recharging electric vehicles, real-world charging times will have to be as short as possible. This means that the battery packs of electric cars will need to be charged with a current of up to 500 kW in order to receive a sufficient charge for a range of 100 km within three to five minutes. “We will need sufficient energy to cope with these high charging capacities, and one way of doing this might be to provide local energy storage facilities,” explains Eva von der Weppen, press officer for Phoenix Contact.

This makes it possible to reduce the connected load of the charging park to the minimum required, so that there is always sufficient energy available at motorway service stations, for example. In addition, these charging stations must be able to deliver the high charging capacities to the electric vehicle safely and conveniently. We already offer a viable commercial solution, in the shape of our cooled HPC (High Power Charging) charging cables,” notes von der Weppen. This presupposes (she adds) “that the battery packs in electric cars can take the high charging capacities, and that they have been engineered for a sufficient number of charging cycles to ensure a long service life. Further work is needed to resolve these technical issues.

ABB is also working on the charging infrastructure. At last year’s Hannover Messe, ABB unveiled its Terra High Power charging station, with a charging capacity of up to 350 kW. This is capable of delivering a charge sufficient for a range of 200 km in just eight minutes – which makes the latest top-of-the-range model from ABB ideally suited for use in motorway service areas and filling stations. As a result, this product from ABB is being installed in growing numbers worldwide so that there are already thousands of fast charging stations in operation in 60 countries. This makes ABB one of the world’s leading suppliers of DC charging solutions – charging technologies designed for the electrification not only of cars, but also of buses, trucks, ships, railways and cable cars.

Hannover Messe is the perfect place for ABB and other specialist exhibitors large and small to get talking with customers from all over the world, and thus to drive the mobility revolution fueled by renewable energy.

FuturENERGY Dec. 18 - Jan. 2019

The unsustainable mobility milestones implemented in little more than a century at global level can only be changed when the different societies that comprise our “global village” become truly aware of the multiple problems involved in pursuing the current model and in parallel, identify the existence of viable alternatives. The most visible part of the problems is currently focused on the large conurbations and can be seen in the millions of journeys made using private vehicles and the resultant damage they cause such as pollution, air quality, public health and the use of space… By EV Division at Circutor.

A new business campaign designed to fast-track the uptake of electric vehicles (EV) and infrastructure was launched by The Climate Group at a unique event in New York, as business and government leaders gather at Climate Week NYC.

Baidu, Deutsche Post DHL Group, Heathrow Airport, HP Inc., IKEA Group, LeasePlan, METRO AG, PG&E, Unilever, Vattenfall are the 10 first members of EV100, the only initiative of its kind to encourage global business commitments on electric transport, with members swapping their large diesel/petrol vehicle fleets to electric vehicle fleets and/or installing electric battery charging infrastructure by 2030.


EV100 is being launched at a time when the transport sector is the fastest-growing global contributor to climate change, with businesses owning a significant portion of all registered vehicles on the roads. EV100 will draw on business leadership to accelerate the shift to electric transport and help to make electric vehicles “the new normal” by 2030.

EV100 will use companies’ collective global buying power and influence on employees and customers to build demand and cut costs. The members see the business logic in leading a faster transition and addressing local air quality issues in their markets. They are setting a competitive challenge to the auto industry to deliver more EVs, sooner and at lower cost.

Together, EV100 members will send a strong market signal that there is mass demand for electric vehicles by 2030 or before, well ahead of current forecasts for global uptake. By setting out their future EV purchasing requirements on an ambitions timescale, these big purchasers can drive mass roll-out, reduce costs, and make electric cars more rapidly affordable for everyone around the world.

Companies joining EV100 make a public commitment to fast-track EV uptake in one or more of the following four commitment areas by 2030:

Transitioning vehicle use to EVs
1. Integrating electric vehicles directly into owned or leased corporate fleets:
– 100% of vehicles up to 3.5 tonnes to be EV.
– 50% of vehicles between 3.5 tonnes and 7.5 tonnes to be EV.

2. Placing requirements in service contracts for electric vehicle usage:
– Daily rental.
– Contracted taxi providers.
– Car sharing.

Installing adequate charging infrastructure
3. Supporting staff to use electric vehicles (by installing workplace charging infrastructure):
– Appropriate set of charging infrastructure installed at all relevant premises.
– Dedicated information and awareness program / appropriate incentive schemes to promote EV usage and reduce the cost of switching to an electric vehicle.

4. Supporting electric vehicle uptake by customers (by installing customer charging infrastructure):
– Appropriate set of charging infrastructure installed at all relevant premises.
– Dedicated customer engagement program to promote EV usage.

Berlin-based Hubject GmbH is a new member of AEDIVE, the Spanish Cluster for the Boosting and Development of the Electric Vehicle market (Asociación Empresarial para el Desarrollo e Impulso del Vehículo Eléctrico, in Spanish). With its eRoaming platform Hubject connects charging station operators and emobility service providers in real-time, in order to provide electric vehicle drivers with customer-friendly access to charging infrastructure.

Hubject already connects more than 280 companies in 24 countries throughout Europe, Asia, and Oceania via the intercharge network. Therewith Hubject created a unified international charging network that allows digital cross-provider access for EV drivers.


With the approval of the plan Movea 2017 the Spanish government strengthens its commitment towards electric mobility. As part of the support programme Spain will invest 14.6 million euros in the development of public charging points as well as the purchase of plug-in electric vehicles (PHEV) and battery electric vehicles (BEV).

The cooperation between AEDIVE and Hubject is a necessary step towards transnational communication about interoperability solutions, which are crucial to the successful deployment of charging infrastructure. It will encourage knowledge transfer, and strengthen competitiveness, research and development. AEDIVE proves its ambition to establish Spain as a strong player in the European emobility market.

For us, working together with national associations and committees is essential. No one knows the local emobility market better than they do – the opportunities as well as challenges. By joining AEDIVE we also aim at sharing our experience in the field of interoperability and new value added services. Thus, we want to support national stakeholders to develop state-of-the-art charging solutions, which will meet customer needs.” says Hubject CEO Thomas Daiber.

In Spain, GIC (Gestores Inteligentes de Carga – Grupo ACS), Electromaps, Urbener, Estabanell Energia, Atos and Circontrol are already partners of the intercharge network.

The 278 charging points set up every 80 km along Germany and Belgium’s main motorways, will allow drivers of electric vehicles to “refuel” and extend their car’s range. The total investment of the EU-funded cooperation is approximately €18 million.

Every one of the multi-standard fast-chargers spread out over four countries have AC and DC connections, allowing drivers to charge their vehicles’ batteries easily and quickly. Electric vehicles can be charge up to 80% on the charging stations within an hour.

Renault sells more electric vehicles in Europe than any other car manufacturer and had a market share of over 23 percent in 2015. Indeed, nearly one out of every four electric vehicles sold in Europe comes from the French manufacturer.

Under the leadership of the charging station operator Allego, the project Fast-E brings together nine companies in the industry, including three charging station operators (RWE Effizienz, enviaM and Allego) as well as four car manufacturers (Volkswagen AG, BMW AG, Renault SAS, Nissan Center Europe), DB Energie GmbH, a subsidiary of Deutsche Bahn and the Hamburg-based company hySolutions, which, as a competence centre in several charging infrastructure projects, is responsible for the integration of new drive technologies in urban transport. The quick-charging stations installed as part of the project employ the Combined Charging System (CCS) and CHAdeMO, each with up to 50 kW power output, as well as a type 2 connector with 43 kW power output. The project is expected to end in December 2017 with the completion of the accompanying studies; the charging infrastructure will continue to operate commercially thereafter.

Schneider Electric and BMW i have started developing in Spain their joint global agreement on electric mobility signed by the two firms in 2013. Schneider Electric has designed an advanced performance Wallbox exclusively for BMW for residential use which will enable anyone who buys a BMW i3 or BMW i8 to charge, safely and speedily, their vehicle at home or in the office. The BMW i3 is the first electric vehicle to reach the market designed from the outset to be charged up at home. The German automotive firm launched the BMW i range last November, with sales forecasts of 10,000 units for 2014. However, just a few weeks after going to market, the BMW i3 already had 8,000 firm orders, most of them for the 100% electric vehicle, which suggests sales forecasts for the whole year will be beaten.
The BMW i Wallbox unit allows the user to charge immediately, that is, simply pressing the start button once the cable is connected, or else on a time delay, using a timer. To turn off, it also has two functions. Firstly, the automatic off function, once the battery is completely charged, or the manual turn-off control, by pressing the off button.
