How Do EV Chargers Work?

When you plug your EV into a charger, it communicates with your vehicle to determine the appropriate charging parameters. This process ensures safe and efficient charging, tailored to your EV’s battery specifications.

Basic Working Principles

1. Plug-In and Authentication:

  • When an EV is plugged into a charger, the charging process begins. Modern chargers often require authentication via RFID cards, apps, or other methods to initiate charging.

2. Communication and Control:

  • The charger and the vehicle communicate to negotiate the maximum charging rate based on factors like battery state of charge, temperature, and available power from the grid.

3. Conversion of Electricity:

  • For Level 1 and Level 2 chargers: Alternating current (AC) electricity from the grid is supplied to the vehicle’s onboard charger, which converts it to direct current (DC) suitable for charging the vehicle’s battery.
  • For DC Fast Chargers: Direct current (DC) electricity is supplied directly to the vehicle’s battery, bypassing the onboard charger, which allows for faster charging rates.

4. Battery Management System (BMS):

  • The vehicle’s BMS manages the charging process, monitoring battery temperature and voltage to optimize charging speed and protect the battery from damage due to overcharging or overheating.

5. Charging Completion and Termination:

  • Once the battery reaches its preset charge level or the user terminates the charging session, the charger stops supplying electricity. Most chargers provide indicators or notifications when charging is complete.

Safety Features

EV chargers incorporate several safety features to protect users, vehicles, and electrical systems:

  • Ground Fault Protection: Detects and interrupts leakage of current to the ground, preventing electric shock.
  • Overcurrent Protection: Prevents excessive current flow that could damage the charger or the vehicle.
  • Temperature Monitoring: Prevents overheating of the charger and the vehicle’s battery during charging.
  • Authentication and Authorization: Ensures that only authorized users can access and use the charger, preventing unauthorized usage or tampering.
