Custom Lithium Battery Pack Project Management, E-bike Battery Pack Design

19/7/2019, Friday, Sunny. After over10 years of accumulation in China's power battery industry, there has been a very big improvement, in particular, the understanding and knowledge of the power battery. With a succession of battery fire, power battery safety is a sensitive topic, but also a topic can not be avoided. How do we know power batteries? The following factors need to be considered before designing a power battery: Battery modules and battery pack (system) assembly ability design, mountability design, maintainability design, adjustable design, recycling and easy-to-dability design. If these performance problems are not solved, the lithium batteries will become "time bombs". Lithium-ion battery is mainly composed of six parts: positive, aluminum foil, negative pole, copper foil, diaphragm and electrolyte. The electrolyte inside the battery contains a large amount of organic matter, such as ethylene carbonate, diethylene carbonate, and dimethyl phosphat...

The rapid growth of China's new energy vehicle production and sales has directly led to the development of power batteries, not only that, at present, China's power battery market is basically dominated by local enterprises. 2017, the CATL by virtue of lithium iron phosphate and NMC lithium ion battery two routes continue to advance, market share successfully surpass BYD, become the first supplier of domestic power battery. BYD also began to gradually give up lithium iron phosphate batteries, switch to the NMC lithium ion batteries. Another hand, BYD cooperated with Chang’an(CHONGQING CHANGAN AUTOMOBILE Co., Ltd) to develop power batteries and committed to new energy electric vehicle development.  Lithium-ion batteries are widely used in lithium iron phosphate batteries[LiFePo4] and NMC lithium ion batteries[Li(NiCoMn)O2], these two types of lithium-ion batteries lead the power of the battery two era. First of all, the lithium iron phosphate battery, although the current mark...
