 With the increasing consumption and limited storage of fossil energy, the world is facing a new round of energy crisis. How to make use of the new energy and improve the efficiency of the traditional energy are the two main subjects to handle the crisis. Considering the convenience of transportation, application and storage in electricity is the most important energy style related to our daily life. Nowadays rechargeable battery is more and more popular in electric energy storage. Unfortunately, we find battery is only a storage material and can't compute itself. Just as the hearties can't perform well without a CPU, enabling the battery to sink is just the essence and value of legal. We focus on providing the world leading management system of electric energy storage, which transform innovative concept to energy industry. For the first time, the breakthrough technology successfully realizes the chemical electric energy storage with large capacity, higher security, long life cycle and reliability. It manages the electric storage from eight aspects, electric, heat, status, security, availability, data, interaction and balance. It has been widely applied in electric vehicle backup power, new energy access, smart grid and power supply in the rural areas. Due to the excellent personnel who aspiring to achieve the perfect successful practices in 46 nations, 227 highly flexible and accurate models of battery and continuous technological innovation. We make the electric energy storage cleaner and more efficient. Now, more than 36,000 legal BMS models serve in 46 countries. Reduce tons of carbon emission that benefited from advanced technology and products. We fed for bad city by applying it to green cars which effectively reduce carbon emission. We fed for the rural area by applying it to new energy exercise which make billions of people obtain power supply. We fed for enhancing communication by applying it to communication system which will make waves never disappear. We fed for life lasting by applying it to life saving system which make people in danger reduced. Of course, it's just a beginning. Legal will realize energy saving and emission reduction in a more scientific and controllable manner thereby offering continuous driving force for sustainable utilization of new energy and social development.
