1. An apparatus for automatically computing work accuracy of a battery management system (BMS) offline and configured to detect the work accuracy of the BMS offline connected to a battery pack, the apparatus comprising:

  • a vehicle control unit, connected to the BMS and configured to send a work command to the BMS and compute the work accuracy of the BMS according to a parameter fed back by the BMS;

    an automobile component simulation module, connected to the battery pack and vehicle control unit separately and configured to provide energy consumption and charging, required by an automobile component, of energy of the battery pack according to the work command of the vehicle control unit;

    a thermal management module, connected to the battery pack and the vehicle control unit separately and configured to perform heat dissipation on the battery pack according to a command of the vehicle control unit; and

    wherein the automobile component simulation module comprises;

    an adjustable resistor energy-consuming component, comprising a first relay and an energy-consuming resistor and configured to provide the energy consumption, required by the automobile component, for the battery pack according to the work command of the vehicle control unit; and

    an excitation charging component, comprising a second relay, an excitation power source, and a protective adjustable resistor and configured to provide the charging, required by the automobile component, for the battery pack according to the work command of the vehicle control unit.
