Product Introduction
Overcharging and overdischarge are the most feared things in the use of lithium-ion batteries. Once overcharged or overdischarged, the battery performance will be damaged, such as capacity reduction and life reduction. In severe cases, it will burst and catch fire. The spontaneous combustion events of electric vehicles that occur from time to time are the best proof, which are the consequences of the problems in the function of BMS system of automobiles, thus showing the importance of BMS system.
In addition, lithium-ion batteries are more prone to overcharge or overdischarge when used in groups, which are all caused by inconsistent parameters of single batteries. Due to the inconsistency of battery parameters, there are differences in battery voltage, internal resistance or SOC value of single battery during charging or discharging. If the charging and discharging process is not effectively controlled, the differences of these parameters will be further amplified, which will eventually lead to overcharge or overdischarge of some batteries, resulting in the decline of battery capacity and life.
Generally speaking, electric vehicles are powered by battery packs composed of individual cells connected in series. Usually, the number of individual cells can reach hundreds.BMS (Battery Management System) is a management system specifically for lithium batteries.
Product Function
BMS ODM and OEM PCBA Service has three main functions:
(1) Monitor the battery status in real time. Mainly by detecting the external characteristic parameters of the battery, such as voltage, current, temperature, working time, etc., and then estimating the internal state parameters of the battery, such as SOC (state of charge of the battery) and SOH (state of health of the battery), with an appropriate algorithm, which is the basis and key for the effective operation of the battery management system.
(2) Realize the functions of thermal management, balance management, charge and discharge management, insulation resistance detection, fault alarm and so on.
(3) Exchange data with display system, vehicle controller and charger through bus (CAN, Ethernet, etc.).

FAQ
1
Q：For ODM service, if you can provide software design?
A：Yes, we can provide not only the software design, but also the firmware design.
2
Q：What's your L/T for PCBAs?
A: Sample is 4W,for mass order, the materials generally need 8W, and the production needs 4W. Materials that are longer than 8W we can stocked for customers. Most of the materials we can stocking for customers for free, but we need to confirm if the materials are special and only used by your company that other customers can not use them, which need your to pay the deposit.
