How EV Charging Works? (What Type of EV Charging Station Available)
Electric vehicle charging systems are a lot more advanced when compared to conventional battery chargers, although their primary function is the same. They need to load energy into the batteries as fast as the batteries can permit and monitor the battery parameters such as voltage and temperature during the charging process for safety purposes.
Typically a charging set up involves a wall charger or a charging station that plugs to the electric grid and safely allows electricity to flow to the car. To make it safer and more reliable and Electric Vehicle Supply Unit (EVSE) is used in between the charger and the car. The EVSE is a wall-mounted box that regulates the recharging of EV batteries by acting as two-way communication and sets the right charging current based on what the battery can take and what the charger can provide. It offers several safety features to protect from power outages, excess loads, faults, and short circuits. They also come with added features such as authentication, software for remote monitoring, and integrated payment gateways.
For now, there are three levels of charging available internationally.
Level 1 Charging: Level 1 is 120 volts, which is the lower limit of the charging stations and is widely popular as they can charge both all-electric cars and plug-in hybrids from homes. They are slow, however, and can take up to 12 hours to charge.
Level 2 Charging: The Level 2 uses 240 volts and can handle much heavier charging loads. Practically all types of electric vehicles can charge at this level in a few hours.
Level 3 Charging: Level 3 uses direct current (DC) and a specific vehicle port to charge the batteries rapidly. These chargers can fill a battery to 85% capacity in less than half an hour.
