Akasol offers three new lithium-ion battery systems
Akasol introduced its first cylindrical-cell battery system with high energy density (221 W·h/kg). AKAModule 60 CYC allows the building of high-energy battery systems of 40 kW·h thanks to its modular structure. This is intended to enable long-distance journeys for commercial vehicles such as intercity coaches, buses, and trucks while simultaneously offering a long lifetime. Compared to current technology, this new system will reportedly allow electric vehicles to increase their range by more than 60%.
The compact size of AKAModule 60 CYC fits the PHEV2 standard module and can be built into a system environment. Despite its high energy density, this 2.66-kWh battery module offers a power density of up to 433 W/kg and high cycle stability in comparison to other high-energy solutions (1500 to 3000 operative cycles). The new battery module will be used first in customer application trials at the end of 2018, and afterward it will enter series production.
The AKAModule 60 CYC as well as two other new lithium-ion battery systems, the AKASystem 15 OEM 37 PRC and the AKASystem 15 OEM 50 PRC, are 700 x 150 x 1700 in size and contain 15 battery modules with different cell technology fitting the PHEV2 standard module. When demands on performance, energy, or cycle stability change at a later stage, users can exchange systems.
The AKASYSTEM 15 OEM 37 PRC is a PHEV2 standard module with prismatic battery cells. It is the first generation of Akasol’s high-performance battery systems. A similar model is used in electric bus Citaro by Daimler’s subsidiary EvoBus. It is mass-produced in Germany. Fitted with PHEV2 battery modules with high power density (up to 870 W/kg) and based on prismatic lithium-ion cells, this battery system brings together high cycle stability (up to 3000 cycles) and high performance for utility vehicles.
The AKASYSTEM 15 OEM 50 PRC, available from the end of 2019, is a PHEV2 standard module with prismatic battery cells. This system uses the next generation of high-performance battery modules with high power density (up to 833 W/kg) and significantly higher energy density (approximately up to 183 W·h/kg) based on prismatic lithium-ion cells. This battery system is poised to allow electric vehicles to increase their range by up to 35% while occupying the same space as the currently available system and maintaining the same lifetime (up to 3000 cycles). It is planned for series production at the end of 2019.
Stephen Raiser, Co-founder and head of development at Akasol, said, “Our new cylindrical-cells battery module allows coaches, city buses, and trucks to operate reliably on long-distance journeys. Since the driving range of those vehicles increases significantly, the need for charging stations will decrease considerably for many applications.”
