LARGE ELECTRIC VEHICLE POWER STRUCTURE AND ALTERNATING-HIBERNATION BATTERY MANAGEMENT AND CONTROL METHOD THEREOF

摘要

Provided is a method for controlling the sequential rest ranking of battery boxes of a power supply architecture for a large electric vehicle. The power supply architecture comprises an electronic control unit with a ranking control unit, a plurality of variable-configuration series connected type battery boxes and a motor device, wherein each variable-configuration series connected type battery box also comprises a plurality of battery modules. The method for controlling the sequential rest ranking of battery boxes comprises the following steps: an electronic control unit calculating the demanded number of battery modules and variable-configuration series connected type battery boxes (S21); the electronic control unit executing a temperature protection program (S22); a ranking control unit calculating a module integration and generating a battery module ranking (S23); the ranking control unit starting the battery modules according to the demanded number and the battery module ranking (S24); the ranking control unit calculating a battery box integration and generating a battery box ranking (S25); and the ranking control unit indicating the variable-configuration series connected type battery box located at the end of the battery box ranking to enter a sleep mode (S26).
