    Abstract: A battery equalization 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.

    Abstract: The present application discloses a battery equalization system, a vehicle, a battery equalization method, and a storage medium. The battery equalization system includes: a collection circuit; an equalization circuit; a controller; a charging branch circuit, connected to a charging device and a battery pack; and a first power supply branch circuit, connected to the charging device and the battery equalization system, and configured to supply power to the battery equalization system. When a state-of-charge of the battery pack is full and a cell in the battery pack needs enabling of equalization, the controller controls the charging branch circuit to disconnect, and controls the first power supply branch circuit to keep connected, so that an equalization module performs equalization processing on the cell that needs enabling of equalization.

    Abstract: A system architecture, a battery management system controller, and a vehicle are provided. The system architecture includes a first function trigger, a logical processor and a second function trigger, which are connected in sequence. The first function trigger is used for reading a function value of an external function and outputting the function value to the logical processor. The logical processor is used for executing preset computation logic according to the function value and outputting a first computation result to the second function trigger. The second function trigger is used for writing the first computation result into the external function. When the system architecture is in an offline debugging state, the logical processor is in a separated state in which the logical processor is respectively independent of the first function trigger and the second function trigger.
