Electric Vehicles Could Combat Cold Climate Conditions with Automatic Charging Battery

EVS sustains in a warm climatic condition, and the people of California buy this kind of vehicles rather than purchasing electric vehicles, as they are cool and can’t live in a cold climatic condition. However, conventional lithium-ion batteries will not be charged immediately below 50 degrees Fahrenheit. Considering to this a group of Penn state engineers has designed a significant battery, which should heat automatically and charge directly even if in the cold climate.  

The assistant professor, Xiao-Guang Yang, of Penn State, is a mechanical engineering and said that in the west coast the electric vehicles are more popular because of its favorable climate condition. But if you move them to Canada, which is in the East coast, then there will be specific changes. They have demonstrated that the batteries will be charged immediately and automatically at outside temperature. 

When in 15 minutes the car owners could recharge car batteries at a station, the time of electric vehicle recharging can be equivalent to gasoline refueling, in which the drivers would be more, and their vehicles could run long distance. Beforehand the community of researchers discovered an automatically heated battery to eliminate the power drain of the vehicles below freezing point. Presently this same technique is being used to charge 15 minutes quick charging at all temperatures such as below 45 degrees F. 

The automatic battery heating uses nickel foil, as its one end is attached to the negative terminal and the other end is connected outside the cell and create a third terminal. When the temperature is lower than room temperature, then at that time a temperature sensor is connected to an electron switch, which completes the flow through nickel foil. This immediately heats up the battery through nickel foil, and the cell remains warm within. 

Chao-Yang Wang, William E said that their unique kind of cell would do the heating and be switching to charging more automatically and rapidly. Lithium-ion batteries are immediately accused in any climate condition, even if below 50 degrees F. This will not reduce its capacity in cold weather. Conventional cells tested under the same terms and it has lost 20 percent of its position in a 50 cycle charging cycles. The rapid charging method will ensure manufacturers to apply smaller batteries, which are safer and lighter in a vehicle to use, which is stated by Wang.
