Based on several years’ production experience on lithium-ion battery, Sichuan Changhong Battery Co., Ltd. has developed wide varieties of Lithium-ion battery protectors, e.g. lithium-ion battery pack guard plate, single cell voltage monitoring board of lithium-ion battery pack and other devices, which are widely used in the fields of electric bicycle, UPS power supply, aviation and so on.
Changhong Battery can supply protection scheme of 1-20 bounces of lithium-ion battery pack with not only the functions of overcharge protection, over-discharge protection, output short circuit protection, discharge over-current protection, equalization charging and other functions, but also the characteristics of low power consumption, high resistance to electromagnetic interference. And some devices has passed the test of national military standards for electromagnetic compatibility.
In addition, Changhong Battery can supply the single cell voltage detection scheme of lithium-ion battery pack in series(over 20 cells) which adopt voltage isolation detection and transmit to the upper computer through RS485, RS232 and other buses, with the advantages of high detection accuracy, high speed, etc.
Changhong Battery has designed and developed the dedicated protection circuit of LiFePO battery pack for electrical bicycle which has passed actual application test and been in favorable results. Changhong Battery can design intelligent protection scheme according to the users’ requirements which can test the battery pack residual capacity, voltage, current, temperature and other parameters and transmit to the upper computer by communication buses.
