Method for displaying voltage of high voltage network of electric car, involves determining whether voltage is applied at high voltage network, and outputting signal to outside of vehicle based on determination of voltage applied at network

摘要

The method involves determining whether a voltage is applied at a high voltage network (3) of a vehicle (1), and outputting a signal to outside of the vehicle using a display unit (16) based on the determination of the voltage applied at the network, where the voltage amounts to 3-60 volt. An operating mode of the vehicle is determined and output. The network is optionally coupled with an electrical energy storage unit using a battery management system (15). Operability of the display unit is checked, and malfunction of the display unit is displayed based on the checked operability. The operating mode is selected from a group consisting of a locking state of a vehicle, seat occupancy of the vehicle, a movement state of the vehicle, an unlocking state of the vehicle, and/or an opening operation of the vehicle. The signal is selected from a group consisting of an optical signal, an acoustic signal and/or a radio signal. Independent claims are also included for the following: (1) a display device for a vehicle (2) a vehicle.
