1. The basic structure of pure electric vehicles A pure electric vehicle refers to a new energy vehicle that uses a power battery as an energy storage power source, and provides electrical energy to the drive motor through the power battery to make it run, thereby driving the electric vehicle forward.
The working principle of pure electric vehicle utilizes use of an electric machine (electric motor) utilizing an energy source (battery) by replacing the internal combustion engine (ICE) and the associated fuel tank, and the energy source of the vehicle gets recharged as they are used to regain their energy source [ 32, 33, 34, 35 ]. Figure 1.
Pure electric vehicle has incomparable advantage over conventional ICE vehicles in terms of energy conservation, zero emissions, and ensuring oil supply security, etc., leading to attraction of wide range of automobile manufacturers and governments.
The renewable energy stored in the batteries is converted into rotating mechanical energy by the electric motor propulsion system to drive the vehicle. Therefore, the renewable conversion efficiency of the electric motor propulsion system also affects the driving range and performance of EVs.
In EVs, there are various circuit topologies for power conversion units used in inverters. The most common type is a two-level three-phase voltage source inverter. Power semiconductors play a leading role in inverter efficiency, power density, and reliability.
The battery delivers current at a particular voltage. Power flowing into the battery needs to ensure of delivery of the correct voltage. Similarly, the power delivered by the battery must ensure the capability of electric machine to propel the vehicle.
