The battery coolant circuit is connected in series with the motor coolant circuit or the engine coolant circuit to utilize waste heat recovery when there is a need for heat production. When the battery temperature is higher than the target value, the air conditioning system will turn on Valve 2.
In future solutions of battery cooling concepts, the exergy losses in each of the components should be minimized to increase the total efficiency and the cruising range, which will finally lead to a reduction of the total lifecycle costs.
The battery cooling system included a pump to control coolant flow rate, a flow meter, RTD sensors for fluid temperatures, an external chiller for maintaining coolant temperature (-25°C to 100°C), and a heat exchanger connecting the coolant cycle with the external chiller.
As mentioned earlier an additional component, as the chiller in the battery cooling system, will lead to higher exergy losses and consequently to a reduction of efficiency. One proposal to reduce the exergy losses is to use the cooling plate of the battery unit as a direct thermal connection to the refrigeration cycle.
Coolant flow rate increases drastically once the temperature of the Battery is over 0 °C due to the definition of the Pump control because of which the Pump now runs at maximum rpm. The dip in Coolant temperature can be explained to be due to the Coolant Heater being switched off, although this is momentary.
It was discovered that the TEC system has a substantial impact on the pack's cooling performance and keeps the battery temperature lower than 30 °C. Increasing the flow rates on both the cold and hot sides of the battery will potentially lower the average battery cell temperature by 3 °C–5 °C.
