UITP Global Public Transport Summit 2019


Long-range, fast-charge: AKASOL presents lithium-ion battery system advances at UITP Global Public Transport Summit

At the UITP Global Public Transport Summit 2019, AKASOL will present a broad portfolio of new long-range, fast-charge solutions to the public transport community. The company’s flagship product is the new high-energy battery AKASystem AKM CYC, which has entered series development for the battery module and system. AKAModule CYC achieves market-leading energy density of 221 Wh/kg with liquid cooled battery modules, which are scalable and can be integrated into various system designs at the pack level.

With this high-energy solution for long-range applications, AKASOL will set a new energy content benchmark for public transport. For example, fully-electric city buses can be equipped with battery system capacities between 600-1,000 kWh, depending on the vehicle size, which more than doubles AKASOL’s existing series-produced technology currently in use in Daimler EvoBus’ eCitaro.

The new AKASystem AKM CYC can be charged up to 1C – more than enough for today’s fast chargers for commercial vehicles, limited to a maximum power of 500 kW. For manufacturers this means their buses can be charged by up to 80% in just 45 minutes and fully charged in just an hour.

The AKAModule CYC comes in two standard versions. The small version (AKAModule 64 CYC) is the same size as the PHEV VDA battery module standard and is thermally managed with internal cooling plates. The large version (AKAModule 150 CYC) has an integrated liquid cooling structure, ensuring very efficient thermal management of each battery cell in larger module design.

To achieve very high energy density in combination with the required charge and discharge power, AKASOL decided to use special 21700 cylindrical cells. These are specifically designed for use in professional and commercial applications in terms of calendar and cycle life. With this technology, AKASOL is able to outperform today’s solid-state technology in terms of price competitiveness and availability, while increasing energy density by around 30-40%. The solution can also be used for fast charging, which is particularly important for increasing the uptime of commercial vehicles. AKASOL plans to bring the solution to series production in 2021 and already has customers starting sample operation by the end of this year.

2nd Generation AKASystem OEM PRC approaches serial production

AKASOL will also present the 2nd generation of the AKASystem OEM PRC at UITP. The first generation powers the Daimler EvoBus eCitaro with an installed capacity of up to 294 kWh – and is also utilized by a major Swedish manufacturer of buses and trucks. The 2nd generation will offer an energy increase of more than 33% and achieve around 400 kWh installed capacity in the same installation space on a 12m city bus. The system can achieve charge rates of 2 C and can be fast-charged (even with smaller installed battery packs) with up to 500 kW at the most powerful charging stations for commercial vehicles currently on the market, making it a suitable option for both opportunity and depot charging.

The 2nd Generation AKASystem OEM PRC is currently in the test and validation process and will be available at the end of 2019, going into serial production for two major commercial vehicle customers in the middle of 2020. The Daimler subsidiary EvoBus has confirmed that it will be a repeat customer. Production will take place at AKASOL’s battery system production facility, which is already the largest in Europe and will expand to a total capacity of 800 MWh next year.

Following on from its successful 2018 IPO, AKASOL continues to exhibit dynamic growth as it expands its portfolio of solutions for commercial vehicle electrification not only in Germany but throughout Europe and worldwide. AKASOL will this year expand into the US market following the creation of its North American subsidiary, AKASOL Inc. The company is also beginning construction of its state-of-the-art new headquarters in Darmstadt, Germany, which will be four times larger than its current production facility in Langen and is set for completion in mid-2020.

AKASOL CEO Sven Schulz commented: “We offer the public transport sector a range of advanced lithium-ion battery systems that are outperforming current solid-state solutions. Setting new industry benchmarks for energy density, price competitiveness and availability, our flexible high-performance systems meet the rigorous demands of the public transport sector and support the quest for cleaner and quieter cities.”
