Abstract:
A hybrid vehicle includes a multi-mode power system. The power system includes a battery, an electrical power input, a first motor/generator, a second motor/generator, and a clutch. A first operating mode is defined by deactivation of the internal combustion engine and the operation of the vehicle by electrical force provided from the battery to the second motor/generator. In a second operating mode, activation of the internal combustion engine generates electrical power by providing rotational force to the first motor/generator. In a third operating mode, engagement of the clutch couples the internal combustion engine and the second motor/generator to provide rotational force to the wheels. In a fourth operating mode, engagement of the clutch couples the internal combustion engine with the second motor/generator, and the first motor/generator further provides rotational force to the wheels.

A hybrid vehicle includes a multi-mode power system. The power system includes a battery, an electrical power input, a first motor/generator, a second motor/generator, and a clutch. A first operating mode is defined by deactivation of the internal combustion engine and the operation of the vehicle by electrical force provided from the battery to the second motor/generator. In a second operating mode, activation of the internal combustion engine generates electrical power by providing rotational force to the first motor/generator. In a third operating mode, engagement of the clutch couples the internal combustion engine and the second motor/generator to provide rotational force to the wheels. In a fourth operating mode, engagement of the clutch couples the internal combustion engine with the second motor/generator, and the first motor/generator further provides rotational force to the wheels.

Abstract:
The present application relates to a battery equalization method and system, a vehicle, a storage medium, and an electronic device. The method includes: obtaining a voltage value of a to-be-equalized cell in a battery pack; obtaining a reference voltage value required for equalization; determining a target equalization duration of the to-be-equalized cell according to a voltage value of the to-be-equalized cell, the reference voltage value, and a preset equalization duty cycle, where the equalization duty cycle is a ratio of an equalization period in a unit cycle to the unit cycle, and the unit cycle includes the equalization period and a sampling period; and controlling equalization of the to-be-equalized cell in the equalization period in the unit cycle according to the target equalization duration. According to this method, sampling is separated from equalization in a unit cycle, thereby ensuring accuracy of collected battery information, making the calculated equalization duration relatively accurate, and improving equalization effects of the battery pack.
