Third generations of Akasol batteries split in two
Akasol will attend Busworld 2019 in Brussels showcasing the new high energy solution AKASystem AKM CYC, whose series production is expected to start in 2021. Brussels exhibition will also be the place where the fuel cell solution AKASystem OEM PRC will be launched: 50 demo vehicles will be in operation from 2020 onwards. Finally, the 48V solution AKARack for hybrid and all-electric applications will see the light at Busworld.
According to battery supplier Akasol, the one chosen by Mercedes for the AKAModule CYC and by Volvo for the 7900 Electric, «the European market for hybrid and electric buses is forecast to grow by more than 26% annually».
AKASystem AKM CYC
The future flagship of the company, Akasol says, is the high-energy battery AKASystem AKM CYC, which will be produced at the new headquarters in Darmstadt, Germany starting in 2021 and at the new US headquarters in Detroit (USA) starting in 2022 as part of a recently agreed production order from a leading global commercial vehicle manufacturer. Cells will be provided by Samsung SDI.
The lithium-ion battery AKAModule CYC used in this third-generation system achieves an energy density of approx. 221 Wh/kg with the aid of liquid-cooled battery modules.
Akasol to equip mild hybrid buses
According to Akasol, this new solution (suitable for rapid charging at a maximum output of up to 500 kW) will allow city buses to be equipped with battery capacities of between 600 and 1,000 kWh, depending on vehicle size, and thus have twice the storage capacity of today’s battery generation.
The battery module AKAModule CYC will be available in two standard versions. The small version (AKAModule 64 CYC) is the same size as the standard PHEV VDA battery module and is heat regulated by means of internal cooling plates. The large version (AKAModule 150 CYC) has an integrated liquid cooling structure, enabling highly efficient heat management of every battery cell, even in larger module designs.
