Level 3 EV Charger: Delving into DC Fast Charging
You might encounter various terms for Level 3 charging such as rapid charging, fast charging, ultra-fast charging, or DC charging. Essentially, these terms are often used interchangeably and all point to the same type of high-speed EV charging. The key differentiator is the use of Direct Current (DC) instead of Alternating Current (AC).
What Exactly is Level 3 EV Charging?
At its core, level 3 EV charging is the quickest way to replenish an electric vehicle’s battery. It leverages high-power DC charging stations to deliver electricity directly to the EV battery, bypassing the limitations of the vehicle’s internal AC-to-DC converter. This direct delivery of DC power is what enables the significantly faster charging speeds.
How Does Level 3 Charging Work?
To understand the efficiency of Level 3 charging, it’s crucial to grasp the difference between AC and DC power. The electrical grid primarily distributes power as Alternating Current (AC). However, EV batteries store energy as Direct Current (DC).
-
AC Charging (Level 1 & 2): With Level 1 and Level 2 charging, the AC power from the grid enters the vehicle and is converted to DC by an onboard charger within the car itself before being stored in the battery. This onboard charger has a limited conversion capacity, which restricts the charging speed.
-
DC Charging (Level 3): Level 3 chargers are smarter and more powerful. They contain a large AC-to-DC converter within the charging station itself. This conversion happens outside the vehicle, and DC power is then directly fed into the EV battery, bypassing the vehicle’s onboard charger. This direct DC power delivery, at a much higher amperage and voltage, is what achieves rapid charging.
