Beijing Jingyi: Breaking the short-lived problem of bicycle lithium batteries

The battery life of electric bicycles is getting shorter and shorter, which is a difficult problem for consumers. Beijing Jingyi Jingye Electrotechnical Technology Co., Ltd. has recently developed a smart lithium battery module controlled by a battery management system (BMS), which has achieved no reduction in battery life for bicycles up to four years and 1000 cycles, and doubled the battery life of electric bicycles.

"The same theory with the barrel, the traditional lithium battery life is rapidly declining, the battery life is short, not all the battery pack battery life is exhausted, but individual 'lazy' batteries dragged down the 'hard' battery. If each The battery can work in the best condition to the last moment, and the overall life of the battery can be greatly extended, which requires a 'control' system to manage and balance the performance of each battery, and our battery control management system (BMS) has solved this problem precisely." Zhao Jianhe, director of lithium power project of Beijing Jingyi Jingye Electric Technology Co., Ltd. said.

In the dedicated technology workshop, a row of new lithium-ion bicycles are ready to go. A block of lithium battery was installed under the seat. It is these lithium battery modules weighing only 3.5 kilograms each, which solves the long-standing troubles of consumers of many electric bicycles.

In early 2012, the smart lithium battery developed by Dedication Technology passed 1000 charge and discharge tests in a charge and discharge tester, and the battery capacity was maintained at 10 Ah, maintaining the “factory” state. At the time, R&D personnel shouted with excitement because it meant that their smart power modules ensured that the electric bikes could travel 40,000 kilometers steadily.

"Our smart power module technology, whether used on electric bicycles or on electric vehicles, costs only one-tenth of the world's equivalent products," Zhao Jianhe said. (Intern reporter Sun Qiru)
