German battery manufacturer Akasol has developed two new production sites: a new facility with over 3,000 square meters of production halls and office space in Langen, and an additional 700 square meters in Darmstadt.

The automated production line in Langen will be set up by the end of 2017, and starting in 2018, up to 150 members of staff will begin series assembly of lithium-ion battery systems for European bus manufacturers. The plant will have a total capacity of up to 300 MWh, enough to equip about 1,500 e-buses annually. The company plans to expand capacity to up to 600 MWh per year in a second phase.

At the new plant in Darmstadt, small-scale series production for orders in the commercial vehicle, railway and marine industries has already begun.

Both facilities were designed to be sustainable, and were built to the latest standards. The German Sustainable Building Council certified the building according to the 40 DGNB Gold standard, which represents the highest level of sustainability.

The company also developed a modular lithium-ion battery system designed for use in commercial vehicles such as buses, trucks, construction equipment and specialty vehicles.

The base unit has a storage capacity of 24.4 kWh at a voltage level of 661 V (nominal) and power of 150 kW (peak). A theoretically unlimited number of additional modules can be added in parallel and in series. The battery modules are made by major battery manufacturers.

The modules are designed to be very compact. A water/glycol cooling system, developed by Akasol, ensures a uniform temperature.
