25 Kilograms of Pure Energy

25 kilograms: That’s the weight of the hybrid battery in the Mercedes-Benz S-Class S 400 HYBRID, which will be launched in 2009. The battery consists of 35 cylindrical, rechargeable lithium-ion batteries and delivers a peak power of up to 15 kW (20 HP). The electric and thermal protection of this little bundle of energy is one of the battery ECU’s most important tasks. The ECU’s algorithms were developed in a joint venture between Johnson Controls and SAFT. dSPACE TargetLink is used to generate the ECU software.
