Powerful boost: lithium-ion battery supplies up to 100 kW of power
Underneath the inside floor, roughly in the middle of the passenger compartment, lies a compact lithium-ion battery weighing less than 60 kilograms (132.3 lb) and featuring highly performance-optimized cells. It can temporarily deliver up to 100 kW of power to the electric motors, while its energy capacity is limited to around 1.8 kWh. The storage battery operates over the range of 220 to 460 volts – a high-efficiency triport DC converter in the engine compartment equalizes the difference compared with the fuel cell’s voltage level.
Two power electronics units convert the direct current into alternating current for the two high-performance electric motors. The front electric motor generates 90 kW and the rear one 140 kW. Their housings incorporate planetary gear trains with a single transmission ratio; a mechanical parking lock and a differential function round off the system.
A separate low-temperature circuit keeps the driveline and high-voltage battery components sufficiently cool even when the car is driven sportily.
