No battery management battery pack is a bomb. BMS, ie, the battery management system is the core power battery pack, balanced load power, service life, safety, etc., are required BMS to control and optimization in the new energy automotive industry chain, industry value BMS is very important. Public information, BMS prevent over charge, avoid over discharge, temperature control and maintain the battery pack voltage and temperature balance, remaining battery capacity and predict the remaining mileage and other features. Meanwhile, BMS also has real-time monitoring and adjustment of the battery state management capacity, ability to work synchronized with a plurality of parallel subsystems. Through BMS can accurately measure the condition of the battery pack for solar powered portable generator, the battery will not overcharge and discharge protection, balancing a battery pack each battery charge, as well as analysis and calculation The battery pack and convert endurance understandable information to ensure battery safe operation.
The power of storage battery pack and battery management system was listed as key research tasks, "BMS charging infrastructure protection needs for the response rate of 100%" is listed as one of the operational safety ,and technical aspects of interconnection of electric vehicle infrastructure assessment indicators. Although BMS is very important for electric cars, but because of the relatively low proportion of the cost of the vehicle, the vehicle for a long time without the attention of enterprises, the lack of design and production experience,portable solar power generator product BMS should do fine and stronger domestic business journey in the field of power battery BMS is still a long way to go, but because of the sudden outbreak of new energy automobile production and sales, the rapid expansion of downstream applications market is not growing enough to BMS industry time.Until 2020 years, the market of vehicle battery power will reach 120 billion yuan. Wherein, BMS system used by passenger cars account for about 10% -16%, commercial vehicles accounted for about 3% -5%, when the domestic electric vehicle market will reach 17 billion yuan BMS.
