Abstract
The present disclosure relates to a battery management system for energy control and, more specifically, to a battery management system for controlling energy by stably managing, using a new current management means, battery conditions that change due to internal or external factors during the charging and discharging process of a battery cell, so as to enable optimized charging and discharging of the battery cell.
Claims23
A battery management system for energy control configured to balance a voltage of each cell in a state in which a plurality of battery cells is connected to each other, the battery management system comprising:
- a voltage measurement device;
- a switch configured to be opened and closed according to the voltage;
- and
- a current management means configured to consume or utilize a bypass current bypassing one or more of the battery cells when the switch is closed, wherein the bypass current is consumed or utilized for temperature management of the battery cells.

A battery management method comprising:
- measuring a voltage of battery cells connected to each other, the voltage of the battery cells being increased to perform voltage uniformity matching between the battery cells when measuring the voltage;
- performing selective switching such that a bypass current selectively flows to one or more loads connected to each of the battery cells;
- checking each of the one or more loads that consume or utilize the bypass current after each switch is actuated for a corresponding one of the one or more loads;
- and
- performing relatively rapid cell balancing of the battery cells to achieve stable thermal management compared to a conventional method that does not utilize the bypass current.
