BTMS needed to remain the battery more safety, longer life and higher performance in Energy Storage Systems.

Through innovative thermal management system scheme, Ethermal provide a efficient and long life system.

We use different working mode to cooling and heating battery. We use compressor when ambient temperature is high and radiator when ambient temperature is not too high, and we use Heatpump when ambient temperature is low. All of these are designed to make the system higher COP and longer life up to 15 years.
