Li-Ion linear charger... Battery management ICs play an important role in ensuring the safety of users, while making sure they get the most out of their battery-powered devices. Battery management solutions require accurate voltage, current, and temperature measurements to determine the exact state of charge of batteries and battery packs.
The key to ensuring the performance and reliability of energy vehicles is the BMS, in which BMIC is responsible for accurately monitoring various battery cell data. A 16-cell stackable battery monitoring and management chip using 0.18 μm high-voltage BCD technology was designed in this study.
They ensure proper charge and discharge of lithium battery packs which controls the temperature of each lithium cell to avoid hazardous breakdowns, and also balances and protects each cell in the system. BMSs are key components of EV batteries, typically representing about 15 % of overall system costs.
The chip was implemented based on a 0.18 μm BCD process, and the area of the proposed BMIC was 3 × 3 mm 2. 1. Introduction Battery management systems (BMSs) are widely used in electric vehicles (EVs), energy storage, and high-power portable equipment, and are the control core of the energy supply system.
Since a chip monitors up to 12 series cell voltages, the battery pack is divided into four modules, each module is connected in series by 19 single cells, that is, the battery management system monitors 19 single cell voltage information from the module, that is, each slave control module should use at least 2 LTC6803 battery monitoring chips.
The battery management system is mainly used to intelligently manage and maintain each battery unit, prevent the battery from overcharging or overdischarging during use, prolong the service life of the battery, and monitor the working state of the battery in real time .
