Akasol has announced the launch of three new lithium-ion battery systems for all-electric and hybrid city buses, intercity buses and coaches.
The company’s AKASystem AKM CYC battery system will be produced in Darmstadt, Germany from 2021 and in Detroit, USA from 2022 as part of a recently awarded series order for one of the world’s leading commercial vehicle manufacturers.
The third-generation AKAModule CYC lithium-ion battery module achieves an energy density of approximately 221Wh/kg with the aid of liquid-cooled, scalable battery modules at the system level. All-electric city buses could therefore be equipped with battery capacities of between 600-1,000 kWh, depending on the vehicle’s size.
Furthermore, charging could take place at a rate of 1C. Akasol says the charging capacity will be up to 500kW. Manufacturers should therefore be able to charge their vehicles up to 80% in 45 minutes and fully charge in around 90 minutes. Akasol achieves this energy density and charging and discharging capacity with the use of 21,700 round cells.
The AKAModule CYC battery module will be available in two standard versions. The small version (AKAModule 64 CYC) is of the same size as the battery module standard PHEV VDA and is heat regulated through in-system cold plates.
The large version (AKAModule 150 CYC) has a liquid cooling structure integrated into the module to enable highly efficient heat management of each battery cell, even in larger module designs.
