While charging an electric vehicle is generally safe and straightforward, it’s important to understand and follow a few best practices to minimize risk and prolong equipment lifespan.
Use certified chargers and cords. Always purchase chargers that meet safety standards, such as UL or CE certification. Avoid knockoffs or unverified accessories that could cause damage or fire hazards.
Keep equipment dry. Modern chargers are weather-resistant, but you should still avoid charging in standing water or during heavy rain unless the equipment is rated for outdoor use. Wall-mounted chargers should be properly sealed against moisture.
Inspect cords regularly. Frayed cables or cracked plugs can lead to shorts or overheating. Replace any damaged components immediately and ensure connectors fit snugly.
Don’t use extension cords. Most manufacturers advise against them, as they may not support the necessary amperage. If unavoidable, ensure the extension cord is rated for EV use and doesn’t overheat.
Ventilation matters. Some older EVs or lead-acid battery chargers generate heat or gases. If you’re using such systems in a garage, ensure proper ventilation to avoid buildup.
Charging in extreme temperatures. Cold or hot weather can affect charging efficiency. While modern EVs manage this automatically, it’s best to avoid extreme heat and precondition the battery in cold conditions.
Follow installation guidelines. For Level 2 chargers, use a licensed electrician to install dedicated circuits. Improper setup can trip breakers or damage your home’s electrical system.
Charging your EV safely ensures not only the longevity of your equipment but also peace of mind every time you plug in.
