The electric car battery thermal design application
Lithium ion batteries have become the dominant power because of platform, high specific energy, specific power voltage, low self-discharge,
cycle-performance Blade Electric Vehicles powered by lithium-ion batteries have become a hotspot of international competition. International mainstream car
companies will push electric cars based on lithium ion batteries in the next few years. Many experts think that lithium ion power battery like that today's
oil has important strategic significance. However, lithium ion battery produces a lot of heat when used. It will cause the battery temperature rises highly and
battery pack asymmetry between various battery temperatures so that it will affect the performance of the battery. When serious, it even affects the battery life
and use safety. So it has an important practical significance that it uses numerical simulation methods to analyze the battery under the condition of using the
temperature field distribution, optimizing the structure of heat dissipation of the battery pack and predicting the heat dissipating performance.
So using numerical simulation methods to analyze the battery under the condition of using the temperature field distribution, optimize the
structure of heat dissipation of the battery pack, the heat dissipating performance of prediction, to improve the use performance of the battery pack
has important practical significance. The battery pack heat dissipation in a car uses the cooling fan suction type structure commonly. Our company has cooperated with BYD and other famous electric car manufactures to produce high performance of heat sinks.
