Cooling system for Electric vehicles and Hybrid Electric vehicles usually consists of two separate cooling circuits, one specifically for the Battery and another for the electrical components. The cooling circuit for the Battery looks as shown in the Figure 2-3.The Coolant flow throughout the system is maintained by the Pump.
Also, as the ambient temperatures go higher, operating just the Chiller is the best option for cooling the Battery. There is always a trade-off between power consumption and cooling provided. It is necessary to maintain the balance and try to minimise power consumed by the cooling system.
The cooling in such batteries is provided by air or liquid cooling as discussed earlier in section 2.7. The heating up of the Battery is associated with energy provided for the vehicle from the point it starts functioning. Because the Battery is very heavy, its placement plays a very vital role.
The cooling circuit mainly consists of two 3-way valves, a Coolant Heater unit, an electric Pump, a separator assembly and an expansion tank, all of which are modelled and calibrated separately and are in the form of sub-assemblies with open links on its ends.
An HVAC Control Module. Depending on the ambient temperature, it may be necessary to heat or cool the high-voltage battery. It is possible to accomplish this using the same systems that heat and cool the cabin. Alternatively, a separate heater could heat the coolant flowing into the battery.
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.
