EV Charger Installation Sydney

1. Chargers for E-Mobility should be connected using its own cable

No additional appliances should be connected to the cable running directly from the fuse box and the charger. Additional appliances could include washing machines, lights and general household appliances. The utilization ratio will be calculated systematically to be 1 since it takes several hours to fully charge the batteries of vehicles powered by electricity. The circuit that is dedicated to the wall box or charging station is required to adhere to local AS3000 standards. The load connected to the charging station should be able to be fully respected.

2. Choose the right cable for EV Charging

If cables aren't thick enough, they can become hot and there is the risk of burning cables. When the current of charging is at or above 16A, we recommend using a cable with a minimum cross-sectional area of 2.5 millimetres or greater which allows the car to be fully charged using an energy capacity of 11-22 kW. If you are using the use capacity of a 3-phase charger, that requires a 5-conductor power supply cable as well. The diameter of the cable will depend on the length of the cable, as well as the potential drop, the temperature of the environment and kind of installation. Therefore, it's recommended to consult a certified electrician at Platinum Solar Group to identify the correct size of cable you will need. It is recommended to prepare cables that have a three-phase connection (when feasible) to make sure that your project is future-proofed. Electric cars in the near future will feature faster charging speeds and bigger capacity batteries.

3. Residual Circuit Device (RCD) for safety in Electric Vehicles

Residual current devices (RCD) are designed to protect against electric shocks. The RCD regulates the electric currents in the neutral and live wires that connect to and from the appliance, or in this case the electric vehicle. If these currents aren't any longer balanced, as in when a residual current is flowing through the bodywork of the vehicle or driver, and then to the floor, then the RCD triggers and cuts off the circuit. To ensure this happens when an RCD has not been integrated in the charging station every charging station has to be equipped with a unique RCD. To ensure safety, the RCD has an RF diversity of 1.0, meaning that each circuit needs to be secured individually.

4. What Types of Recurrent Current Devices are Available?

A RCD that is rated type A is the minimum required for every charging station. Type A RCDs are an ordinary RCD protection switch used by certified electricians that only registers certain fault currents. Some electric cars may generate smooth DC fault currents during charging. If you can't rule out such a possibility a suitable DC protective device for residual current should be put in place. There are many options to address this.

• RCD Type B: A type B RCD can be described as "sensitive to any current" and can recognize all kinds of AC and DC residual currents and is well-suited to charger station installations. This is the preferred RCD of choice in this scenario.
• The various chargers of the Platinum Solar Group range include an integrated RCD, Type A or B.

5. Installing the correct circuit breaker that matches your charger

The circuit breaker makes sure that the circuit will be shut off in the event that too much power circulates across the cables. This will ensure that damage to cables by the heating process can be prevented. Like the RCD, it is necessary to have an additional circuit breaker for a new charger station circuit.

The manufacturers of our electric vehicle charging stations suggest circuit breakers that have the characteristic of tripping C.

The circuit breaker should be aligned with the nominal voltage, for the necessary charging power. It poses a risk of risk to the safety of others, so the installation must be performed by a licensed electrician. They are accountable to ensure that all current guidelines and standards for installation are adhered to.
