Figure 4. TEC-based BTMS module and performance testing: (A) Configuration of the basic thermal unit setup; (B) Block diagram of the thermal management system; (C) Heating test at 4 Amps; (D) Cooling test at 10 Amps. Temp@A refers to the temperature at the hose system and near the TEC. Temp@B refers to the temperature at the bottom end of the front battery[55]. TEC: Thermoelectric cooler; BTMS: battery thermal management system.
