Smart battery for electric vehicles provides a range of 400 km


A team of engineers from Pennsylvania State University promises to end the English term “alarm” or “Range Anxiety”. This behavior is known among electric vehicle owners as the fear that the vehicle will run out of energy before it reaches its destination.

Iron phosphate batteries may be a solution. Chao-Yan Wang, director of the university’s Electrochemical Motor Manufacturing Center, said his engineering team has created a smart battery that could revolutionize the electric vehicle industry in the future.


According to Wang, the solution the researchers found is not only innovative but also inexpensive, and the cost is comparable to the production of a traditional combustion engine.

Iron phosphate batteries provide a range of more than 400 km and have a sufficient resource to cover more than 3200 km. Unlike traditional batteries, the component can still be charged in just 10 minutes. This is another factor that Wang says could end fear of running out of energy before reaching the charging station.

The secret to extended autonomy and faster recharging lies in the ability of the iron phosphate battery to automatically heat up and cool down. This clever process, developed by Wang and his team, uses a thin layer of nickel foil to operate. One end of the nickel foil is attached to the negative terminal of one of the battery cells and the other end extends outside the cells.

Когда электроны начинают проходить через батарею, она быстро нагревает никелевые листы, постепенно повышая внутреннюю температуру компонента. При достижении 60 градусов по Цельсию железо-фосфатная батарея готова к использованию или перезарядке.

По словам Ванга, этот интеллектуальный процесс также позволяет использовать недорогие материалы в катоде – электроде, с которого ток выходит из поляризованного устройства, – и в аноде – электроде, через который положительный электрический заряд течет в поляризованное устройство. Катод изготовлен из фосфата лития и железа, что исключает использование более дорогих материалов, таких как кобальт. С другой стороны, анод состоит из крупной частицы графита.

Wang concluded by saying that he has finally found a battery that can benefit the average consumer in the electric vehicle market. “This is how we are going to change the environment, not just promote luxury cars,” he said.

Finally, the engineer says the set of iron-phosphate batteries produces enough power for an electric car to go from zero to 100 km / h in just three seconds. Something comparable to a sports car from renowned car manufacturers such as the German Porsche.
