Abstract

The present invention provides a controller, system and method for managing a battery pack. The battery controller includes a first drive port, a second drive port and a third drive port. The first drive port is coupled to the charging switch for turning on the charging switch to allow the power source to charge the battery pack. The second drive port is coupled to the first discharge switch for turning on the first discharge switch to allow the battery pack to supply power to the first load. The third drive port is coupled to the second discharge switch for turning on the second discharge switch to allow the battery pack to supply power to the second load. The invention utilizes independent discharge switches and corresponding drive ports, so that the battery controller can independently control each discharge circuit.

Description

technical field [0001] The invention relates to a battery management system, in particular to a controller, system and method for managing battery packs. Background technique [0002] figure 1 A conventional battery management system 100 is shown. The battery management system 100 includes a front-end circuit 112 , such as a digital front-end circuit (DFE) or an analog front-end circuit (AFE). The front-end circuit 112 monitors the voltage of each of the plurality of battery cells 110 included in the battery pack, as well as the current and temperature of the battery pack. A plurality of battery cells 110 are charged by a power source 118 and may power a load 116 . Data related to the battery cells and battery packs is communicated from the front-end circuitry 112 to a conventional microcontroller unit (MCU) 114 . Based on this data, the MCU 114 monitors the safety and health of the battery pack. Safety conditions include overvoltage, undervoltage, overtemperature, shor...
