How to connect the ground wire of charging pile

If it is in a villa area or a village in the city, users usually live alone in a building with a relatively independent power supply system. Every household user will have a grounding rod in the incoming distribution box, which can be directly led to the charging pile from here. Most of the incoming distribution boxes in old houses don't have grounding rods, so we have to find ways to make grounding points and use them as ground wires. The simple manufacturing method is as follows: 1.

If it is in a villa area or a village in the city, users usually live alone in a building with a relatively independent power supply system. Every household user will have a grounding rod in the incoming distribution box, which can be directly led to the charging pile from here. Most of the incoming distribution boxes in old houses don't have grounding rods, so we have to find ways to make grounding points and use them as ground wires.

The simple manufacturing method is as follows: 1. Buying a grounding rod online, the specification is about 1.5 meters long and the thickness is 1 cm. The size is not limited, which wastes a lot, but it is difficult to hit if it is too small. 2. Select the installation position of the grounding rod and drive it into the soil below. You can pour a bag of 500 grams of salt into the hole. Objective To increase the conductivity of grounding, and then put the grounding rod in. 4. Leave the grounding rod outside to connect the ground wire (choose 4 or 6 squares), pay attention to rust removal, and pay attention to firm binding and waterproof after connection. 5. Finally, the measured value of grounding resistance shall prevail, generally less than 4 ohms is qualified. When the grounding requirements are high or the grounding resistance can not meet the requirements, various methods and measures such as adding salt can be considered to improve the grounding effect. If it is a high-rise residential user, the parking space is generally in the underground parking lot, which is far from each household's independent electric meter, so it is unrealistic to connect the household's own distribution box. Then you should consider the following possible ways to connect electricity. 1. Power supply in the hotel. Generally, considering the power capacity and fire protection, 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 this 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 takes electricity. After the owner applies for installation, the applied meter generally has no grounding wire to connect. There are many available ground wires in general underground parking lots. First of all, it is more convenient to choose a nearby ground wire than to do it yourself. Common grounding wires are bridge, fire cabinet floor row, etc.

Will the balance be refunded after the charging pile is fully charged?

No. There are three payment methods for charging piles, namely coins, credit cards and code scanning payment. Coins and credit cards are prepaid. If the customer charges the battery in advance, the remaining fee cannot be refunded. If it is code scanning payment, there will be no overpayment.

Except that some old charging piles are prepaid by credit cards and coin-operated, the new charging piles are charged according to the quantity, and how much is charged. Generally, commercial electricity is around 1.8 yuan. Electricity prices are different in different regions, so the specific charging standards of charging piles will be different. The battery capacity of new energy vehicles is about 3 1 kW, and it needs about 3 1kWh, and it costs about 55.8 yuan to charge once. This is a commercial charging method for fast charging and charging piles. If it is slow charging for home use, the charging pile adopts ladder electricity price, which is generally around 0.5 yuan. The battery capacity is also 3 1 kWh. It takes about 15 yuan to charge once, but the speed will be slower. After the charging pile is fully charged, the remaining money will not be returned, especially for coins and credit card payment. The user ends the charging ahead of time, and the remaining money cannot be returned. If it is code scanning payment, there will be no such disadvantages. Charge first and then pay, and there will be no overpayment.
