We all know that an electric car won’t work without a battery, since battery is the heart of it. Currently, these have been a huge blocks through which individual battery cells and essential technology have been placed.
Generally, each cell should be able to save an exact amount of energy tentatively. This is partly different due to production reasons and their capacities as well vary. This might be pretty hard since all battery cells are connected in series. Therefore the entire battery is only as tough as its weakest cell. When the cell happens to be empty, the rest of the battery’s cell energy will no longer work, so in that case, you have to recharge your car again.
Another deficiency is that, whenever a cell is inefficient, the vehicle will stop working. So it means that the whole energy storage device must be replaced. For this reason, manufacturers are installing cells of same capacity into a battery since various cells are sorted out due to this process, and at the same time pushes up the price of the batteries.
Furthermore, the Fraunhofer research team is now creating a better alternative which they called the “modular battery system”. Every battery cell has its very own microcontroller built-in which records any related physical parameter including the state of charge and the temperature of the battery cell. As an outcome, each cell will be able to know its condition. In addition to that, the battery cells will communicate to each other with the existing power wiring amongst battery cells. This method is known as a power line communication. The cells are also capable of communicating with some other devices like, on board computer that utilizes the information from the cells to evaluate how much energy remains in the entire battery has, the so-called state of charge.
