Electric car motor cooling system.

New cooling system design of bldc motor for electric vehicle using computation fluid dynamics modeling. The teslas ford focus nissan leaf etc. While the evse communications protocol between the charger and vehicle sets appropriate charging currents level 3 power convertors still need effective heat management which usually comes in the form of liquid cooling. The indirect liquid cooling systems for electric vehicles and the conventional internal combustion engine ice cooling system are very similar.

D d motor systems is the premier ev motor manufacturer in the u s. Both circulate coolant throughout a series of metal pipes to transfer heat away from the battery pack or engine. In addition we offer a complete line of u s. The refrigerant loop reverses the effect turning the gas back to liquid.

The drive motor electronics cooling loop is brought into the cabin cooling system through a heat exchanger. The electric motor windings heats up when operated under extreme load and hence reducing the efficiency of the vehicle. For a small to medium light weight ev conversion. Different electric vehicles have different kinds of cooling systems.

Journal of the korean society of tribologists and lubrication engineers 29 5 pp 318 323. So i ll discuss the range of cooling options in those cars. It s a lot more practical than you think. Electric motor performance directly affects the overall performance of an electric vehicle ev.

For maximum life and performance onboard vehicle batteries must be thermally regulated during both operation and charging. For battery powered electric vehicles if the designer plans to use advanced chemistry lithium ion batteries that must be actively liquid cooled then it makes sense to develop a cooling system. Low temperatures decrease a battery s power and capacity reducing range. Wang a heming li cheng tsung liu 2008.

In hot weather the original loop rejects the heat the report said. The simplest ones have only ambient air cooling but those aren t modern production evs sold to regular folks. That s before the site goes on to describe the engine s electronic throttle control auto start stop function direct ignition system with knock control electronically controlled engine cooling.
