The installation of new energy electric vehicle charging piles should be connected to electricity, which belongs to electricity facilities. First of all, it depends on the technical parameters of the matching charging pile of the model you purchased. We mainly look at two points——voltage and power. 1. Voltage: Household charging piles are all AC 220V, so there is no need to worry about the voltage. 2. Power: The common power of 220V AC charging pile is 3.3KW (16A) to 7KW (32A), and the portable charging gun is generally≤1.7KW (8A). Plug-in hybrid electric vehicles are generally equipped with 3.3KW. 7KW is the standard configuration for pure electric vehicles. Pure electric vehicle charging piles that require high power will use 380V voltage and need to apply for a dedicated line. General family only has 220V10KW household capacity. Therefore, charging pile 4S above 7KW cannot be installed for you, and its voltage and power cannot match. It should be noted that voltage X current = power, 220VX32A=7040W is equal to 7KW (1000W=1KW). Charging piles charge new energy vehicles. Long charging time will affect the use of other electrical facilities in your home. As I said just now, the household capacity of an average household is 10KW. Other high-power electrical appliances at home: It can be seen that if you use an instant water heater at home, no matter whether your charging pile is 3.3KW or 7KW, you can say goodbye to charging in the shower. Of course, this problem is easy to solve. Many new energy vehicles have appointment charging. You can set the charging time after 23 o'clock or 24 o'clock, so your family can charge it safely after taking a bath. Avoid using high-power electrical appliances at the same time to avoid overloading. What happens when overloaded? Because there is an air switch in the house, when the current exceeds the air trip current for a period of time, the internal heating will cause the trip. Picture this: Undressing at night, taking half a shower, and tripping! How helpless is the darkness~. How to look at the tripping current of the air breaker~: This kind of C40 means that the air breaker will continue to trip when the current is greater than 40A. When wiring, the working current of the 3.3KW charging pile is 16A, so you should choose a first-stage circuit breaker larger than 16A, such as 25A or 32A. Wire diameter≥2.5mm2 national standard copper wire, 4mm2 is recommended (the wire diameter here refers to the cross-sectional area of the wire). The 7KW charging pile can not only empty the C32, but also trip frequently. Should choose C40 or C60. Wire diameter≥6mm2 national standard copper wire. Moreover, the charging line should be a special line to avoid being separated from other high-power electrical appliances, and use crimping wiring, and it is best not to use a plug. The working current of the portable charging cable is only 8A, and it can be plugged into a 10A wall socket. If you use a mobile plug, the diameter should be≥1.5mm2 national standard copper wire. 3. Charging environmental factors: There must be a grounding wire: the charging pile must be reliably grounded, because the car's shell is mainly covered with metal, although the charging pile. The insulation index of the vehicle meets the relevant national standards, but the grounding wire must not be missing. Especially in rainy days to prevent electric shock. The circuit breaker must have leakage protection: leakage protector, also known as residual current circuit breaker, can cut off the power supply within 0.1 seconds when leakage occurs. Of course, the charging piles of regular manufacturers also have leakage protection, which adds a layer of protection and peace of mind. Rain and damage prevention: The parking space is generally a public area. If it is in the open air, the charging facilities need certain rainproof facilities. Of course, most outdoor charging piles themselves are rainproof, so what you need to consider is how to prevent damage and also prevent others from stealing electricity. Specifications for cable laying: If the electricity is pulled from home, the cable laying must comply with the regulations, and those running through the wall must be reliably fixed with flame-retardant conduits or trunking. It is recommended to bury in the corridor through the pipe. Avoid flying wires. Irregular cable layout may cause risks such as wire falling, entanglement, fire, and electric shock. .
