How many amps is a mode 2 charger?

A mode 2 charger is a type of electric vehicle (EV) charger that is designed to be connected to a standard domestic power socket. It is commonly used for charging EVs at home or in places where dedicated charging stations are not available. The ampere rating of a mode 2 charger depends on several factors, including the electrical wiring in your home and the maximum charging capacity of your EV.

Factors determining ampere rating

There are a few key factors that determine the ampere rating of a mode 2 charger:

Power supply: Mode 2 chargers typically operate on a single-phase AC power supply, which means the ampere rating is influenced by the maximum current your power socket can handle. In many countries, the standard domestic power socket supports a maximum current of 13 or 16 amps.

EV battery capacity: The size of your EV battery plays a crucial role in determining the charging time. As a general rule, the higher the battery capacity, the longer it takes to charge. To ensure faster charging, you will need a mode 2 charger with a higher ampere rating.

Charging speed: Different EVs have different charging speeds. While some EVs can recharge at a rate of 3.7 kilowatts (kW), others support much higher charging speeds, such as 7 kW or even higher. A mode 2 charger should be capable of delivering the required current for efficient charging.

Ampere ratings and charging speeds

Let's consider two common examples:

Example 1: If your EV has a battery capacity of 40 kWh and supports a maximum charging speed of 3.7 kW, a mode 2 charger with a 16-ampere rating will be sufficient. This charger can deliver approximately 3.6 kW of power, allowing you to charge your EV in around 11 hours.

Example 2: If you own an EV with a battery capacity of 60 kWh and a faster maximum charging speed of 7 kW, you will need a mode 2 charger with a higher ampere rating to take advantage of the faster charging capability. A charger rated for 32 amps can provide approximately 7.7 kW, enabling you to charge your EV in about 8 hours.

Consulting professionals

It is important to consult with professionals or refer to the manufacturer's guidelines before purchasing a mode 2 charger. They can help determine the optimal ampere rating based on your specific EV model, electrical system, and charging needs. Installing an inappropriate charger can result in inefficient charging or potential damage to your electrical system.

In conclusion, the ampere rating of a mode 2 charger depends on multiple factors, including the power supply, EV battery capacity, and desired charging speed. Understanding these factors and consulting professionals will ensure you select the right mode 2 charger for efficient and safe charging of your electric vehicle.
