Battery Pack Function Introduction

A battery pack includes a battery pack case, a battery pack connected in series and parallel, a battery management system (BMS), a wiring harness (strong & weak current), strong current components (relays, resistors, fuses,. . Generally, the negative side of the circuit is used to measure the charge and discharge current value of the entire circuit. . There are two types of BMS: integrated type and discrete type. The discrete type is mainly divided into three modules, the main control module. . A battery pack is a set of any number of (preferably) identical or individual . They may be configured in a series, parallel or a mixture of both to deliver the desired voltage and current. The term battery pack is often used in reference to cordless tools, hobby toys, and . A battery pack is a series of battery cells in a module that stores electrical energy and releases power. Inside a battery pack, batteries connect in parallel or series arrangements. [pdf]
