Why does the battery temperature increase during the charging cycle?

It can be seen that during the cycle, there is a steep increase in the Battery temperature despite the cooling system functioning fully. This illustrates the high magnitude of thermal load on the cooling system during this charging cycle.

Why is a battery a high thermal load case?

The temperature of the Battery increases despite cooling provided to it and hence is the highest thermal load case. Coolant flow rate needs to be maximum during this case. The magnitude of temperatures is normalized to 1 as a factor of the maximum safety limit of temperature for the Battery.

Why is a battery temperature normalized to 1?

The magnitude of temperatures is normalized to 1 as a factor of to the maximum safety limit of temperature for the Battery. These are results from running the cooling system to provide warm Coolant to the Battery with an initial temperature of -0.5 °C.

Should I use a chiller to cool a battery?

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.

What is a high voltage battery?

The High Voltage Battery is the most critical part in Battery electric vehicles as the name suggests. The source for electrical energy required by the vehicle is the Battery, the most important being the energy demand of the drive motors and associated components. It stores and provides energy when there is a demand made by the vehicle.

Can PCM cooling solve battery thermal challenges?

Recent review studies have primarily centered on using PCM cooling as a sophisticated solution to tackle battery thermal challenges. The literature lacks a comprehensive study on direct liquid cooling, a crucial strategy for effectively managing thermal aspects in next-generation batteries.
