Vehicle Batteries

The batteries are assembled from SmartPowerBlocks™ (SPB), each of which is protected and monitored by its own SmartBMS™ slave. This keeps energy, weight and voltage small, and service is simplified. Different battery configurations can be implemented by selecting the voltage level of the SPB and connecting different number of SPBs. The SmartBMS™ Master provides all superordinate functions and monitors the entire system. An optional CIM (Customer Interface Module) allows batteries and components to be interconnected, such as embedded charger, power distribution units (PDU), additional batteries (via junction box), system interface to the higher-level system, and operation of one or more top-side 19″ PowerChargers™.

The batteries are partly type-qualified according to MIL-STD. The batteries can be additionally qualified to UN T38.3 on request.
