In the vehicle factory debugging process, set up the mill mode, through the power management function of mill mode, in time judge according to whole car power consumption state to control whole car power consumption demand, in order to prevent the battery insufficient voltage, and then guarantee that the battery can satisfy the demand that the vehicle parked for a long time.

Further, after the power management system identifies and determines whether the first vehicle meets the second predetermined condition, step S300 of the present application further includes:

step S310: and if the first vehicle does not have the debugging requirement currently, entering a first power saving mode to obtain first reminding information.

If the first vehicle does not have a debugging requirement currently, a first electricity-saving mode is entered to obtain first reminding information, wherein the first electricity-saving mode is a ' five-minute electricity-saving mode ', the mode is mainly used for reminding that the vehicle is in an energy-limiting state currently, the first reminding information is that a low-voltage power supply tube sends the ' five-minute electricity-saving mode ' to an instrument, and the instrument reminds that ' the electricity consumption is too much and exceeds a preset threshold value according to the state. The technical effects of timely judging the power utilization state of the whole vehicle, controlling the power utilization requirement of the whole vehicle and preventing the power shortage of the storage battery are achieved.

Further, if the first vehicle meets the first predetermined condition, the first power saving mode is entered, a first reminding message is obtained, the first reminding message is used for reminding that the power consumption exceeds a predetermined threshold, and after power is turned on, step S200 of the present application further includes:

step S210: when the first vehicle meets the high voltage or switching mode or BCM power-off on the vehicle within second preset time, obtaining an instruction of exiting the first power saving mode;

step S220: after the second preset time is exceeded, the HU enters a semi-dormant state, the display screen is closed, and all auxiliary functions are closed;

step S230: when the first vehicle is in a P gear, judging a power supply gear;

step S240: if the power supply gear is an ON gear, powering down to an OFF gear;

Specifically, after entering the "five-minute power saving mode", the mode is mainly used for prompting that the vehicle is currently in the energy limiting state by the meter, the first prompting message is that the low-voltage power supply tube sends the "five-minute power saving mode" to the meter, and the meter prompts that "the electric quantity is excessively consumed and exceeds a preset threshold value according to the state. The second predetermined time may preferably be set to 2 minutes, and the exit "five-minute power saving mode" command is sent when the first vehicle satisfies a high voltage power on vehicle or switches to other modes or when the BCM (Body Control Module) is powered off within the second predetermined time, that is, within 2 minutes.

After exceeding said second predetermined time, i.e. after 2 minutes: HU enters a semi-dormant state, the display screen is closed, and the energy limit level is transmitted highest; each auxiliary function is closed, including air-blower, back defrosting and rear-view mirror heating close, HU is out of work, and the theftproof pilot lamp is closed, and intelligence usher's function and clean wind system function are closed, and seat heating and seat function of regularly ventilating close in the car. When the first vehicle is in a P gear, the P gear is the most common gear in an automatic gear vehicle type, and is generally arranged at the forefront position of a gear operating platform and in front of an R gear, so that the purpose of locking an axle through the gear when the vehicle is at a standstill on a slope is achieved. And judging the power supply gear, if the power supply gear is an ON gear, the whole vehicle is electrified, and the power is automatically turned OFF to an OFF gear, namely the whole vehicle is powered OFF. If the automobile is in the ACC gear, the automobile can be powered on by an internal distributor without starting the automobile, and the automobile is powered OFF to the OFF gear without judging the gear.

step S270: exiting the first power saving mode when the first vehicle satisfies the fourth predetermined condition.

Specifically, when the first vehicle meets the fourth preset condition, the first power saving mode is exited, the fourth preset condition includes that the whole vehicle Ready is powered on from an OFF gear, namely a whole vehicle power-OFF state, or a BCM, namely a vehicle body controller is powered OFF, or a condition of entering a transportation mode or a test mode is met, and the vehicle test mode is a mode for detecting various performances of the electric vehicle. The vehicle transportation mode is that the vehicle-mounted controller can be actively managed in the vehicle transportation process through the control device on the vehicle, so that the static current consumption of the vehicle in the transportation process is reduced, the discharge capacity of the storage battery is obviously reduced, and the risk of starting failure after the vehicle reaches a transportation destination is reduced.

For example, the transportation mode is started in the process of the automobile from a manufacturer to a 4s store, the power of the electric appliances in the automobile is cut off, and the storage battery can be prevented from discharging. After the automobile has started the mode of transportation, except that anti-theft system starts, other each use electrical apparatus not to supply power, in transportation and storage process, prevent the excessive consumption of undercurrent to the vehicle storage battery.
