The invention discloses a vehicle electric energy control method, an electric energy controller and an electric energy control system. The vehicle state of a vehicle is determined, storage battery information is obtained, and when the vehicle is in an OFF state and in a vehicle fortification state, a power supply cut-off instruction is sent according to the electric quantity of a storage battery and vehicle electricity load information; and the intelligent switch cuts off the power supply of the vehicle load according to the power supply cut-off instruction. The power supply of the vehicle load is cut off according to the storage battery information and the vehicle electricity load information, the abnormal current consumption of the vehicle is eliminated from the source, the electric quantity of the storage battery after the vehicle leaves is monitored, the quiescent current consumption of the whole vehicle is reduced to the maximum extent, and the electric quantity of the storage battery can meet the requirement of follow-up vehicle starting. Meanwhile, the vehicle load power supply is directly cut off, the discharge condition of the storage battery is reduced, and the aging speed of the storage battery is reduced.
Description
technical field [0001] The invention relates to the technical field of automobile control, in particular to a vehicle electric energy control method, an electric energy controller and an electric energy control system. Background technique [0002] Modules such as those on the vehicle do not always go into "sleep mode" properly during use of the vehicle. After the vehicle is stationary, the vehicle bus is generally in a sleep state. At this time, the quiescent current of the vehicle is about 20 mA, and the quiescent current generated is not enough to cause the battery to lose power; Networked loads wake up frequently. If the vehicle is woken up abnormally, the quiescent current can reach several amperes, and the vehicle will suffer serious power loss. Affected by impurities in the battery electrolyte, the battery will also have a certain self-discharge current, and its self-discharge will also affect the entire vehicle. A large factor in power consumption, and a dead batter...
