Level 3 charging stations convert alternating current (AC) from the grid into direct current (DC) within the charging station itself, rather than relying on the vehicle’s onboard charger to perform this conversion. This bypass allows for a significantly faster charging process. Depending on the power output and the EV’s battery capacity, Level 3 chargers can charge an EV to 80% in as little as 15 to 60 minutes. This high-speed charging is ideal for short stops along highways, urban fast charging needs, and commercial applications such as fleets of taxis or delivery vehicles.
Level 3 chargers are equipped with different connector types to accommodate various EV models. Common connectors include the Combined Charging System (CCS), CHAdeMO, and Tesla’s proprietary connectors. The power output of Level 3 chargers can vary significantly, with lower-end models providing around 50 kW and high-end models delivering up to 350 kW. This range enables EVs to gain between 150 to 400 kilometers of range within 30 to 45 minutes of charging, depending on the vehicle’s maximum charging capacity and the charger’s power level.
Due to the infrastructure and power requirements, Level 3 charging stations are primarily found in public and commercial locations, such as motorway service areas, urban centres, and fleet depots. The installation and operational costs of Level 3 chargers are considerably higher than Level 1 or Level 2 chargers, making them unsuitable for residential use. Nonetheless, the rapid charging capabilities of Level 3 chargers play a crucial role in reducing range anxiety and supporting the broader adoption of electric mobility.
