Making e-mobility affordable through electronics integration
Handling the high energy flows in an electric car requires special power electronics which operate in 400 V and even 800 V power-nets. These electronics tend to be large, heavy and complex. Current electric car models contain distributed HV electronics – i.e. separate devices for each energy conversion function. The distributed devices not only carry more direct weight and cost, but they also drive the need for more heavy wiring to connect those separate devices. Vitesco Technologies has taken a step towards making e-mobility more affordable by integrating closely related energy conversion functions together in the HV Box and BMS.
Despite the high integration provided by the HV Box, Vitesco Technologies is still able to offer a range of AC charging power levels from 7 kW to 22 kW, compatibility with global electric grids, 400 V or 800 V power-nets, DC-DC power ranges and more. The HV Box and BMS are the result of modular designs and expert system integration knowhow in electronics, mechanics and software, which are at the heart of Vitesco Technologies’ DNA.
Modular solutions to fit carmakers’ diverse vehicle fleets
Since established carmakers have diverse vehicle fleets, there is no ‘one size fits all’. Moreover, every carmaker has their own strategy for E/E integration, in-vehicle voltages, power levels and software functions. Vitesco Technologies’ HV Box and BMS solutions contain the modularity to support many car makers’ strategies. Even within the platforms of a single car maker, Vitesco Technologies covers the needs of the entire fleet, from A segment to SUVs.
The HV Box and the BMS also ensure safe transfer of energy to protect the car’s operator against electric shock. For instance, the BMS contains the intelligence to carefully manage the flow of high current to the battery, to prevent electrical shock or overheating. In the event of a crash, the BMS also triggers the electrical isolation of the battery from the rest of the car.
The modular and scalable concept is a big step forward in making electro-mobility affordable. The HV Box and BMS greatly reduce complexity and help carmakers to reduce the size, weight and cost of electronics and wiring inside the car. Our solutions play a central role in making electric driving safe, affordable and environmentally sustainable
