June 25, 2010, Harbin Power Equipment Co., Ltd. crown Billiton held lithium battery management system (BMS) will introduce new products. At the meeting, representatives of crown extension power around “GTBMS-005A battery management system. To power lithium batteries in electric vehicle applications become possible” to start introducing the topic.

In energy and environmental pressures, new energy vehicles will no doubt become future automotive development direction. However, the development of new energy vehicles to overcome many technical difficulties, including new energy automotive engines and power modules (motor, batteries and battery management systems) and optimization of design, scale of production processes and cost control techniques, namely the “Three” become a focus of research and development of new energy vehicles .

Some people believe that “Three”, the electric vehicle battery development of new energy vehicles greatest obstacle, Tongji University, New Energy Automotive Engineering Center Research Office, Xue-Zhe Wei-board power supply that, although the performance of our batteries have a certain gap with foreign countries, But no one imagined that bad, my VGP-BPS15/B  industry already has in the new energy vehicles, particularly in the application of hybrid vehicles on the basis of. It should be said, affected the development of new energy vehicles in China the main sticking point is the battery management system.

Power lithium battery electric vehicles currently in the field of application of three major bottlenecks:

1, group life and short service life, Sony battery  safety problems still exist

2, the cost of battery costs are higher

3 miles long charging time, Mileage short, inconvenient to use.

Although the battery management system at this stage there are no insurmountable difficulties, but the undeniable battery management system for electric vehicle battery in the application of new energy vehicles on the role of a very large, especially lithium battery electric vehicle batteries into the field and all the necessary group to promote use of the bottleneck areas, mainly in the combined application of fuel cell group of single Zhi battery overcharge or over discharge as such of failure, resulting in decreased performance and an integrated battery pack is unlimited use, a serious impact on battery safety and service life.

The battery management system is mainly responsible for the battery pack evaluation, management and protection, its role must not be underestimated. On the one hand battery management system can monitor real-time operating parameters of power battery pack, battery pack to ensure safe operation, to avoid over-charging the VGP-BPS15  battery, discharge, or overheating and fire, or explosion;
 
On the other hand, the battery management system on battery power the monitoring of operating parameters and the estimated battery state, and scientific management, the battery pack can power every cell in the best working condition to avoid a cell life is not in his life before the arrival of early failure, creating a domino effect, causing the battery not work.
 
As noted above, the battery management system occupies an important role, but currently the slow development of battery management system. Reasons which are not difficult to understand, including two aspects:
1, the battery management system recognizes the serious shortage of battery management system and the current number of errors in management-oriented manufacturing enterprises, directly or indirectly affect the new energy automotive industry’s rapid development has become an indisputable fact.
2, the market is missing battery factory and vehicle business support, R & D battery management system, not only with the vehicle battery factory bench enterprises Canon NB-8L Charger , Nikon EN-EL3  , but also help to complete their long-term attendant battery management system tests. No battery factory and a strong enterprise with the vehicle, the battery management system can not mature.

Despite the presence on the market relatively slow development of battery management system, but as the BMS industry expanded crown pilot who always do the best battery management system, developed battery management system control strategy always cross lines: “Restricted two zones with automatic balanced. ” That by preventing overcharging and over discharging automatically adjust charging parameters to achieve the purpose of automatically equalizing charge.
Limited to two, with the middle, automatic balance.

1, limited to two: charging, not only to prevent over-voltage charge (over pressure protection) also prevent low-voltage charge (over voltage protection); discharge to prevent excessive discharge (over voltage protection)

Second, with the middle: When charging the battery voltage reaches the highest voltage, automatic voltage and current methods of regulation, continue to charge.

3, Automatic equalization: charging, the battery charging characteristics and the use of automatic adjustment method of charging parameters, the battery automatically equilibrium

Crown extension card battery management system (BMS) via real-time monitoring of single cells in series battery voltage, current, environmental, temperature, analyze, judge, on the Nikon charger  battery pack and batteries for each single high-pressure, low pressure, high temperature, low temperature , over-current, short circuit protection, and output alarm and control signals, pairs of charging parameters and electricity Shebei adjust and control that automates the Dianchijunheng, truly: the protection of the power battery Zuyou Xiao, ensures that the battery life group, so that single cells within the battery tends to be more consistent. So that power lithium batteries in electric vehicle applications become possible, and effectively promoted the power lithium battery and electric car industry’s rapid development.

Crown extension always adhere to the advanced technology, excellent service to promote the Sony ac adapter  industry. Continue beyond the innovation, to provide customers the best products, best service for the rapid development of battery technology to provide strong protection. We believe that lithium-ion battery with strong momentum, crown extension will fly higher, farther.
