At NEWBASE, we specialize in the production of advanced Battery Thermal Management Systems (BTMS) for fully electric commercial vehicles. Our water-cooled units are a crucial component of the BTMS, designed to maintain the battery's internal temperature within its optimal operating range. This minimizes the temperature difference between the highest and lowest points inside the battery box, ensuring stable battery performance and extending the overall lifespan of the battery.
