Should I Purchase a New Energy Vehicle Charging Pile Myself?
1 Answers
When purchasing a new energy vehicle, automakers typically provide a 1.7KW portable charger and a 3.3KW wall-mounted charging pile (some electric vehicles come with a 7KW wall-mounted charging pile) to facilitate home charging. Both the portable charger and wall-mounted charging pile can be connected to a household power supply for charging. In daily use, the following points should be noted: 1. Pay attention to wire specifications: Different power appliances require wires of varying thicknesses and circuit breakers of different sizes; otherwise, safety issues may arise, ranging from tripping to fire hazards. The portable charger has a rated power of 1.7KW and can be used with any household socket without affecting the circuit or socket. The 3.3KW wall-mounted charging pile requires a dedicated 2.5-square, 16A air conditioning circuit for safety. For a 7KW charging pile, the wire must be at least 6-square, which is not pre-installed and requires new wiring during installation. 2. Monitor power load: Household circuits have a capacity of 220V/10KW. Overloading can cause tripping or fires. When using a home charging pile, estimate the simultaneous power usage, especially with a 7KW charging pile. To ensure normal operation of other appliances during charging, it is advisable for users with 7KW charging piles to apply for a dedicated power line from the electricity department. 3. Ensure proper grounding: Since new energy vehicles have large metal bodies, proper circuit grounding is essential to prevent electric shock, as per national regulations. 4. Avoid low-lying areas: Charging piles should not be installed in low-lying areas to prevent flooding during heavy rain. 5. Power off and lock after use: Whether installed indoors or outdoors, always power off and lock the charging pile after use to prevent accidental contact by children.
