Tech Highlights

◎Thermal Management：Using CAE simulation technology with experimental data, establish a predictive calculation program. To propose the different cooling technology solution according to different customer operating conditions : 1.Making battery pack housing or holder with heat dissipation material 2.Air cooling solution for low C rate discharge application 3.Air cooling with heat pipe for 1~2C discharge application in small pack! 4.Liquid cooling solution for high C rate discharge application 5.Effective thermal design extends battery life and performance / ◎ Thermal Runaway Control Technology：The safety problems of lithium batteries are mainly due to abnormal use of the battery, including: external short circuit, overcharge, and charging after over-discharge. The occurrence of short circuit problems will cause the cracking of the isolation film, electrolyte, or positive and negative materials, causing the battery to collapse. A large amount of heat is released, causing safety issues such as battery fire and even explosion. Once a fire occurs in an electric vehicle, the energy of the lithium battery continues to be released, so it is difficult to extinguish and will prolong the burning time. The flame-retardant design of the battery pack is particularly important to isolate the fire from the outside and prevent the damage from expanding. This design uses special molding materials and provides choices of coating, sheet and injection methods to match the battery pack design. The material itself is soft and thin, which has little impact on the battery weight, maintenance and disassembly, and does not produce toxic gases. It is an organic/inorganic composite material with halogen-free and low smoke toxicity characteristics. This material can withstand a flame of 1,000˚C. The material itself does not catch fire but only turns to ashes. It also protects objects on the back of the material for up to 60 minutes and maintains the temperature of the backside below 300˚C.
