3 Pin Socket EV Charging Safety : Risks & Solution
Charging an EV on the go is now made more convenient through the use of Portable EV Chargers like the E2. However, not all portable chargers are manufactured to the same safety standards as the E2. This raises an important question often asked by new EV owners: Is 3 Pin Socket EV Charging truly safe even with a good portable charger?
Is It Safe to Charge An EV With A 3-Pin Socket
Yes, it is considered safe. However, only when the socket and wiring installed according to proper standards. Over the years of installation, its been observed that many homes 3 Pin Socket aren’t up to specification for continuous overnight charging- a factor that’s often overlooked by EV owners. Here are some of the risk and ways to overcome the issues of 3 Pin Socket charging.
- The Wiring
- Looping Of Multiple Sockets
- Quality Of The Socket
3 Pin Socket Charging: The Wiring
Undersized cables can pose as a serious threat to the safety of your home as it increases the risk of overheating. Some wall sockets are outfitted with 1.5 mm² copper wiring. Although it might suffice for lower current pulling appliances such as fans and lighting, application such as continuous EV Charging isn’t ideal. Hence, the appropriate socket wiring such as 2.5 mm² or 4 mm² should be made sure before plugging in the portable EV Charger.
3 Pin Socket Charging: Socket Looping & Circuit Load
In order to save cost, some contractors consider looping multiple sockets into a single circuit. Meaning that a series of socket share a single circuit breaker (MCB). A concern for utilizing one of the 3 Pin Socket for EV Charging. Chances of tripping the circuit increases or worse, overheating. Ensure that the 3 Pin Socket used for EV Charging isn’t looped for EV Charging.
3 Pin Socket Charging: Quality Of The Socket
Cheap, non-SIRIM-approved sockets may loosen internally over time due to their unqualified sub-par quality as opposed to sockets that have been approved. Being subjected to long hours of continuous current draw through EV Charging could potentially lead to arcing and plastic deformation. Sockets recommended are those that come from brands that have been given the green light from SIRIM.
