How to connect the ground wire of BYD charging pile

How to connect the ground wire of the charging pile If it is a villa or a village in the city, users usually live alone in the building and have a relatively independent power supply system. In the newly-built villas or communities in the city, there will be a landing bar in the incoming distribution box of every household, which can be directly led to the charging pile from here. If you are a high-rise residential user, the parking space is generally located in the underground parking lot, far away from each household's independent electricity meter, so it is unrealistic to connect the household's own distribution box, so consider the following possible power connection methods: 1. The electricity of the property. Generally speaking, considering the power consumption capacity and fire fighting, the property will reasonably assign a power connection location to nearby owners, and users only need to connect electricity from the lower end of the property distribution cabinet. Usually, the power connection location is located in the power distribution cabinet near the charging parking space. Generally, there are grounding rods or grounding points that can be connected. 2. The power supply bureau is electrified. After the owner applies for installation, there is generally no grounding wire to connect the meter used. Underground parking lots generally have many available ground wires. It is more convenient to choose the nearby ground wire first than to do it yourself. Common grounding wires include bridge and fire cabinet floor row. In electrical system or electronic equipment, it is connected to the ground, shell or conductor with zero reference potential. Generally, the ground wire of electrical appliances is connected to the shell to prevent electric shock accidents caused by insulation damage and electrification inside the shell. Charging pile belongs to electrical equipment, and grounding is essential. Of course, there are also some charging piles of individual manufacturers, and the grounding detection in the shielding charging pile is used for surface compatible charging, and even some car owners agree to shield the grounding detection for blind charging, which is definitely a safety hazard of electric shock.
