Avoid the DC charging trap - high power everywhere charging

摘要

Fast charging is key to enable long range E-Mobility. The mainstream vehicle solution is based on DC, which is not regarding the driver's needs and infrastructure trends. We have analysed deeply the consumer's needs and have revealed, that a combination of both, DC ultra fast charging and AC fast charging up to 43 kW is needed on board of electric vehicles. Supporting these needs, a new system for electric vehicles comprising of e-machine, inverter and DC booster with a minimum of additional components for fast charging is developed and currently integrated into a demo car. The AllCharge system is capable for all kinds of conductive charging with reduced system costs.
