Common EV Charger Installation Errors and How to Avoid Them
Electric vehicles (EVs) are becoming increasingly popular, and with them comes the need for EV chargers. However, there are a few common errors that can occur during EV charger installation, which can lead to problems down the road.
Here are some of the most common EV charger installation errors and how to avoid them:
1. Not using a qualified electrician
EV charger installation should only be done by a qualified electrician. Electricians have the training and experience necessary to safely install EV chargers and ensure that they are properly connected to your electrical system. A lot of companies use people that have done a 2 day course and have soembody in the office (known as a QS) sign off the installation and manage the applications. This means it’s cheaper which is good for you but it might mean that there are issues in the future.
How to avoid it:
When choosing an electrician to install your EV charger, make sure they are licensed and insured. You may also want to ask for references from previous customers or check out there reviews. Even on Electrical Forums most electricians are unsure of what needs to be done I see it all the time, If you want a to do a quick competence check ask them if it needs a “Double Pole RCD or RCBO” or not I see a lot of installers are unaware of this yet iit is the regulations BS7671 Section 722.
2. Using the wrong type of charger
There are different types of EV chargers available, so it is important to choose the right one for your needs. Some chargers are designed for home use, while others are designed for commercial use. There are also different types of chargers that are compatible with different types of EVs. This is very relevant when it comes to hybrids Mercedes have just released a new model that has slower charging due to it beimg a Hybrid…go figure
How to avoid it:
Before you purchase an EV charger, consult with your electrician to determine the best type of charger for your needs.
4. Not properly connecting the charger to your electrical system
EV chargers must be properly connected to your electrical system in order to operate safely. If the charger is not properly connected, it can cause damage to your electrical system or even lead to a fire.
How to avoid it:
Make sure that your electrician properly connects the EV charger to your electrical system.
5. Not getting the necessary permits
In most cases, you may need to obtain a permit from your local government before you can install an EV charger. All chargepoints have to have building regulations approval from your local planning office so you should make sure your installer provides this as do it afterwards can be much more expensive. All registered competent persons can do this for you and it is much cheaper than doing it yourself. You will also need permission from your DNO (District Network Opertor) in London and the South East this is usually UKPN (UK power networks).
How to avoid it:
Use a local registered electrician, of course large companies can do this as well, but using somebody local is better for the environment and the local area, as there is a direct benefit to shopping with smaller companies and staying local.
By avoiding these common EV charger installation errors, you can ensure that your EV charger is installed safely and correctly.
