Abstract
A battery cell balancing apparatus according to an aspect of the present disclosure includes a state of health (SOH) determination unit that determines an SOH for each battery cell of a plurality of battery cells of a battery, a state-of-charge (SOC) measurement unit that measures one or more of a voltage or a SOC for each battery cell of the plurality of battery cells, and a balancing unit that performs balancing for each battery cell of the plurality of battery cells based on one or more of a voltage or an SOC for each battery cell of the plurality of battery cells and an SOH for each battery cell of the plurality of battery cells.
Claims20
A battery cell balancing apparatus, comprising:
- a state of health (SOH) determination unit configured to determine an SOH for each battery cell of a plurality of battery cells of a battery;
- a state-of-charge (SOC) measurement unit configured to measure one or more of a voltage or an SOC for each battery cell of the plurality of battery cells;
- and
- a balancing unit configured to perform balancing for each battery cell of the plurality of battery cells based on the one or more of the voltage or the SOC for each battery cell of the plurality of battery cells and the SOH for each battery cell of the plurality of battery cells.
A battery cell balancing method, comprising:
- determining a state of health (SOH) for each battery cell of a plurality of battery cells of a battery;
- measuring one or more of a voltage or a state of charge (SOC) for each battery cell of the plurality of battery cells;
- and
- performing balancing for each battery cell of the plurality of battery cells based on the one or more of the voltage and the SOC for each battery cell of the plurality of battery cells or the SOH for each battery cell of the plurality of battery cells.
A battery cell balancing method, comprising:
- determining a state of health (SOH) for each battery module of a plurality of battery modules of a battery;
- measuring one or more of a voltage or a state of charge (SOC) for each battery module of the plurality of battery modules, wherein each battery module of the plurality of battery modules includes a same number of battery cells;
- and
- performing balancing for each battery module of the plurality of battery modules based on the one or more of the voltage or the SOC for each battery module of the plurality of battery modules and the SOH for each battery module of the plurality of battery modules.
