The public transport in India is gradually shifting towards electric mobility. Long range in electric mobility can be served with High Voltage Battery (HVB), but HVB can sustain for its designed life if it’s maintained within a specific operating temperature range. Appropriate battery thermal management through Battery Cooling System (BCS) is critical for vehicle range and battery durability

This work focus on two aspects, BCS sizing and its coolant flow optimization in Electric bus. BCS modelling was done in 1D CAE software. The objective is to develop a model of BCS in virtual environment to replicate the physical testing. Electric bus contain numerous battery packs and a complex piping in its cooling system. BCS sizing simulation was performed to keep the battery packs in operating temperature range. Iterations were carried out to achieve uniform coolant flow distribution across battery packs and maintain target coolant flow to attain thermal homogeneity

1D simulation is vital when it comes to analyzing complex systems at vehicle level during concept development stage. Appropriate sizing of BCS could result in maximizing the range of the electric vehicle, prolong battery lifespan and enhance overall safety in major sense.
