Think about safety when charging your electric car
Electric cars can be charged from a regular electric socket, or using a dedicated charging unit or a quick charging station. During charging, a great deal of energy is transferred through the charging cable and plugs, and damaged or faulty equipment may cause overheating and fire.
Damaged equipment may also expose people to mortally dangerous voltages when they touch the car or electric equipment. It is therefore very important that owners and users of electric cars charge their vehicles correctly.
Charging station at your regular parking space
If you have a regular parking space, for example at home, you should install a dedicated charging station, known as a Mode 3 charging system. This is a charging system consisting of a wall-mounted charge control unit with a permanently connected charging cable that can be plugged into the car. The equipment is designed for greater loads than normal sockets and extension cords. This results in quicker charging and reduces the risk of overloading, overheating and fire.
Is your electric car more than 8–10 years old?
Batteries in electric cars deteriorate over time. The technology in battery packages sold today is different from the batteries in your electric car. If you change the battery package, note that the NPRA must approve the change (alteration of the electric car). Obtaining approval is your responsibility, and it is important that you comply with the regulations.
Replacing the battery package with an original battery package from the same manufacturer is considered normal maintenance, which does not require approval.
How to safely charge the battery of an electric car
- Follow the manufacturer’s instructions for safe use.
- Use the original charging cable or a cable with equivalent properties and charging current.
- Avoid the use of extension cords – plug the cable directly into the car.
- Where a portable car charger (PCC) is attached to the charging cable (Mode 2 cable), you must hang it on a separate bracket next to the charging point on the wall or ground pole to avoid damage and overheating of the plug and socket.
- Ensure that the charging cable is not an obstacle to pedestrians and that it is not damaged by traffic during charging.
- Protect electrical sockets and plugs against water, snow and salt to prevent corrosion and poor connections. Close the lid of charging sockets after use.
- Do not use charging cables with visible damage or corrosion on the plug or contact pins. This may damage the socket and be a hazard to others who subsequently use the same socket for charging.
- Follow the manufacturer’s instructions for maintenance.
- Check charging cables, plugs and sockets regularly for visible damage, cracks and signs of overheating (soot and brown marks on the plastic). Damaged equipment must not be used.
- If the plug becomes abnormally hot during use, both the plug and the socket must be checked for faults. Look for colour changes on the plastic on the plug and the plastic around the slots in the socket. If the plastic is brown or black, you must not use the socket / plug until it has been repaired.
- Do not make changes to the charging system or pertaining equipment. Use original or equivalent equipment and follow the manufacturer’s instructions.
