The present invention relates to a method and system for distributing energy of a high-voltage battery of a hybrid vehicle. The hybrid vehicle is equipped with a first motor and a second motor. The method includes: acquiring current power information of the vehicle, the current power information including current battery power information, Accessory power consumption information, first motor power information, second motor power information, and driving demand power information; obtain the discharge demand information of the second motor, and determine the current power distribution method according to the discharge demand information of the second motor; based on the According to the current power distribution method, according to the current power information, the distribution value of the charging power and the discharge power of the first motor, and the distribution value of the charging power and the discharge power of the second motor are calculated. The invention can improve the performance of the hybrid vehicle.
Description
technical field [0001] The invention relates to the technical field of hybrid vehicles, in particular to a method for distributing energy from a high-voltage battery of a hybrid vehicle and a system thereof. Background technique [0002] A hybrid vehicle is generally equipped with two motors, and both motors must obtain or deliver energy from a high-voltage battery to ensure the normal operation of the vehicle. Usually the working states of these two motors are opposite. For example, one motor is responsible for driving and obtaining energy from the high-voltage battery, and the other motor is responsible for generating electricity and delivering energy to the high-voltage battery. At this time, the two will not involve competition for energy from the high-voltage battery. And when the vehicle operation mode requires two motors to drive or generate electricity at the same time, the energy of the high-voltage battery needs to be reasonably distributed to ensure that both can ...
