Exploring On-Board Chargers: A Guide to Different Types

Jul 14,2023 | TCcharger

On-board chargers are essential components in electric vehicles (EVs) that enable convenient and efficient charging. They come in different types, each with its own capabilities and features. In this blog post, we will delve into the world of on-board chargers and explore the various types available in the market, providing insights into their functionalities and applications.

1. Level 1 Chargers: Simplicity and Convenience:
Level 1 chargers, also known as trickle chargers, are the most basic type of on-board chargers. They typically come with the EV as standard equipment and utilize a standard household electrical outlet for charging. Level 1 chargers provide a charging power of around 1.4 to 1.9 kilowatts, which can add approximately 4 to 5 miles of range per hour of charging. These chargers are easy to use and offer convenience for EV owners who have access to a regular outlet near their parking spot.

2. Level 2 Chargers: Faster and Versatile Charging:
Level 2 chargers provide faster charging compared to Level 1 chargers, making them a popular choice for residential, commercial, and public charging stations. They require a dedicated 240-volt electrical circuit and are capable of delivering charging power ranging from 3.6 to 19.2 kilowatts, depending on the charger's capacity and the EV's compatibility. Level 2 chargers can significantly reduce charging time, adding around 25 to 30 miles of range per hour of charging, enabling more efficient and convenient charging options for EV owners.

3. DC Fast Chargers: Rapid Charging on the Go:
DC fast chargers, also known as Level 3 chargers, are high-powered chargers designed for quick charging during long journeys or at public fast charging stations. Unlike Level 1 and Level 2 chargers, which convert AC power to DC power within the vehicle, DC fast chargers deliver DC power directly to the vehicle's battery. They can provide charging power ranging from 50 to 350 kilowatts, depending on the charger's capacity and the EV's compatibility. DC fast chargers can add approximately 60 to 80 miles of range in as little as 20 minutes, offering rapid charging capabilities for EV owners on the go.

4. Inductive Chargers: Wireless Charging Innovation:
Inductive chargers, also known as wireless chargers, are a growing trend in on-board charging technology. Instead of using physical connections or plugs, inductive chargers utilize electromagnetic fields to transfer power wirelessly between the charger and the EV's receiving coil. These chargers require specialized charging pads or stations that align with the vehicle's coil for efficient power transfer. Inductive charging technology is still in its early stages, but it holds the promise of hassle-free and convenient charging without the need for physical connections.

On-board chargers play a vital role in the electric vehicle charging ecosystem, providing the means to charge EVs efficiently and conveniently. Understanding the different types of on-board chargers, including Level 1, Level 2, DC fast chargers, and inductive chargers, allows EV owners to select the appropriate charging solution that aligns with their needs and charging infrastructure availability. As technology continues to evolve, on-board chargers are expected to become more powerful, efficient, and compatible with a wide range of electric vehicles, further driving the adoption of sustainable transportation.
