New Electric Vehicle Battery Sensor Design Could Reduce EV Costs

New Electric Vehicle Battery Sensor Design Could Reduce EV Costs

Each block of an EV battery needs its own voltage sensor. Right? Maybe not. Cell balancing may be changing that in the near future. Engineers at Ruhr-Universität Bochum , a university in Germany, have been working on current and voltages sensors that would help reduce the price and weight of EVs. An example of the sensor circuitry attached to EV batteries for monitoring purposes. How Electric Vehicle Batteries Work In case you already know how EV batteries work, you can skip ahead. Battery-powered electric vehicles utilize electricity that is stored in a battery pack to power an electric motor which then drives the wheels forward. Once the onboard batteries are drained, they can be recharged from a wall socket or a charging station. There are three main components to an EV: electric motor, controller, and battery. When the car is turned on, current flows from the batteries...
