BATTERY CONTROLLER FOR AN ELECTRICALLY DRIVEN VEHICLE WITHOUT ANY LOW-VOLTAGE BATTERY, ELECTRICALLY DRIVEN VEHICLE COMPRISING SAID CONTROLLER, AND METHOD

摘要

The invention relates to an electronic device and a method for an at least partially electrically driven vehicle (electric or hybrid vehicle), which vehicle has an electrical energy store provided for driving the vehicle and comprising energy store cells connected in series as well as a voltage transformer for supplying at least one further electrical load of the vehicle, which voltage transformer is coupled to the energy store. The device is designed to supply at least one of the further electrical loads of the vehicle with current from a number of energy store cells of the electrical energy store connected in series that is less than the maximum number of energy store cells of the energy store connected in series, if a maximum current for the at least one further electrical load exceeds the maximum current available from the voltage transformer. The invention further relates to at least partially electrically driven vehicles that comprise a device of the type above or are suitable for performing a corresponding method.
