The method is used to heat the power battery.

A method of controlling the charge current during charging of a lithium-ion battery. A battery charging controller is based on a Kalman filter, which uses estimated battery states to generate a feedback metric to continually adjust a battery cell model. The battery cell model then delivers data to an optimization process that generates the charge current.

This application embodiment provides a method for equalizing the battery module, an apparatus, a battery module and a power management controller, including: judging whether the first battery core and the second battery core enter their respective fully-charged interval; if the first battery core enters and the second battery core doesn't enter, discharging the first battery core until the second battery core enters; if the first battery core doesn't enter and the second battery core enters, judging whether the maximum value of the first charging voltage of each battery cell in the first battery core is greater than a third preset value; if so, discharging the second battery core until the first battery core enters; if not, controlling both to rest a preset time; after resting for the preset time, discharging the first battery core and the second battery core until the SOC of each battery cell enters a same state.

The present disclosure relates to systems, devices, and methods for analyzing health of vehicle batteries. Vehicle batteries tend to degrade over time. The described systems, devices, and methods quantify this degradation (or quantify remaining health of the battery) by comparing average energy used to charge or discharge the battery by a charge level unit to a nominal quantity of energy used to charge or discharge a battery in optimal health by a charge level unit. Charge data for previous charge events of the vehicle battery can be used in the calculation, and can be filtered by identifying qualified charge events based on at least one of a number of metrics. Usage data for previous usage events of the vehicle battery can be used in the calculation, and can be filtered by identifying qualified usage events or subgroups of usage event based on at least one of a number of metrics.
