11-12M Bus Battery Thermal Management

The optimal operating temperature of the battery is 20° to 45°. If this temperature is exceeded, the driving range and the life of the battery will drop dramatically. What’s more, it may also affect the surrounding equipment and cause the consequences of combustion and explosion. That’s why electric vehicles especially need a battery thermal management system, which we also call a BTMS or battery cooler or battery pack cooling system.
If the battery is below this temperature, its electrochemical reaction activity will become poor and the performance of the battery will be greatly reduced. It may even cut off the power directly. Our product can heat it, so we call it battery heating or battery heater.
The 12-meter electric bus has more passengers and weighs more, so it needs to carry more battery packs, which leads to more heat generation or more batteries that need to be heated, so the battery thermal management capability must be stronger. TKT has a proven battery thermal management system solution.
Note: It is a highly customizable part and we can make it exactly to the customer’s specifications. Both cooling and heating can be achieved.
