Common Questions About Electric vehicle chargers

Q – Can we install an electric vehicle (EV) charger in our house without upgrading the electrical wiring and breaker box?
A – For a 2-pole 50 amp breaker. Next you need 6–2 copper wire to run from the panel to where your car charger outlet is going to be. This might not be easy if you're panel is in the basement, and you need to get to the garage and your house is entirely finished. You need to mount a box and EV outlet in your garage. Depending on how hard it is to do it may cost a couple thousand dollars or more.

Q – How do EV chargers work?
A – The electric motor works on the interaction between the motor’s magnetic field and electric current. Which can be powered by a direct current (DC) source or by an alternating current (AC) source.

Q – How often should EV chargers be replaced?
A – Home EV chargers don’t have any parts subject to huge wear and tear. They are basically a power plug and and switch with some electronics for communication. The connector and cable is probably the most wear item, but that should last the life of the product.

The main reason for failure will simply be bad design, incorrect manufacture or incorrect installatio, possibly physical or environmental damage (plastics degrading).

Havnig said that a key reason for replacing in future maybe for upgrades for smart power application, so it maybe non beneficial to make them last significantly longer than 10 yrs. If an EV charger lasted less than 5yrs I’d say it was defective and unsuitable for the purpose.

Public chargers are another matter, they might be subject to more use and abuse, this will vary hugely between areas and designs.
