Simulation waveforms of a new energy electric vehicle charging pile composed of four charging units Figure 8 shows the waveforms of a DC converter composed of three interleaved circuits. The reference current of each circuit is 8.33A, and the reference current of each DC converter is 25A, so the total charging current is 100A.
The feasibility of the DC charging pile and the efectiveness of the control strategies of each component of the charging unit are verified by simulation and experimental results. This DC charging pile and its control technology provide some technical guarantee for the application of new energy electric vehicles.
Voltage in EVs refers to the electric potential difference supplied to the vehicle’s components, such as the battery, motor, and onboard systems. The voltage determines the amount of energy that can be stored in the battery and then delivered to power the motor.
All EVs are equipped with an on-board charger that can be considered as the average power of 2 kW. It is the most available form for battery charging and can typically charge a vehicle's batteries overnight, as an outcome recharging of the battery will provide four miles of travel per hour (Ahmadian et al., 2015). ii.
This DC charging pile and its control technology provide some technical guarantee for the application of new energy electric vehicles. In the future, the DC charging piles with higher power level, high frequency, high eficiency, and high redundancy features will be studied.
To understand how EV charging works, think of electricity flowing into your car like in a plumbing system. The voltage, measured in volts, is like water pressure, and pushes an electrical current to the vehicle’s battery. The electrical current flow, measured in amps, is like the water’s volume.
