The impact of charging strategies on the electric car’s battery system

There is a rapid development towards more electric cars in society today. However, electric cars need to be charged continuously and many new charging strategies have been proposed. Fast charging, battery replacement, wireless charging, smart charging and vehicle-to-grid are all examples of how we may want to charge our electric cars in the coming years. One goal is that electric car charging should be as quick and smooth as refueling a traditional vehicle. Some may want to charge the electric car quickly with high power even in cold weather, or only charge the electric car when the electricity price is as low as possible to reduce the electricity bill.

But how is the electric car's battery affected by different ways of charging or discharging? The electric car's battery will age differently depending on how we choose to charge the electric cars. This in turn affects, for example, the value and the lifespan of the vehicle. The development of both battery technology and charging strategies is very fast in society, together with new business models for electric cars. Therefore, there is an interdisciplinary research field about the electric car's battery and the choice of charging strategy that can be studied more and continuously going forward.
