Matters needing attention in installation of new energy vehicle charging box

1. Who will install the charging box?

Key points: The charging box must be installed by a professional electrician with electrician operation certificate and in strict accordance with the installation instructions in the user manual. It is forbidden to install the product in any box. The owner can submit the demand to the sales service shop after buying the car, and the service shop will have professionals to install it for you as soon as possible. Incorrect installation has great security risks.

2. What are the installation conditions of the charging box?

correct

1, the installation location must be accessible at any time;

2. Need good ventilation;

3, the installation position should ensure convenient observation indicator and operation;

4. The installation environment should be clean;

5. Specification requirements for cable of charging box: Multi-stranded copper wire is adopted, and the wire diameter of 3.3kw charging box is required to be ≥4mm? ; 7kw charging box requires wire diameter ≥6mm? .

mistake

1. The charging box should not be installed in places with severe vibration and inflammable and explosive (such as combustible gas, steam or dust);

2. The charging box should not be installed in low-lying areas and places where water may accumulate.

Do you know the installation process of charging box?

1. The owner submits the demand to the sales service shop after buying the car.

For cross-regional installation, submit the requirements to the local service store;

Shenzhen area is undertaken by the franchised service shop of Shenzhen Shendian Power Sales Co., Ltd..

2. Whether the service shop communicates with the owner to meet the installation conditions.

The service shop communicates with the owner whether the installation conditions are met, especially:

Whether the installation site selected by the owner meets the installation requirements;

Whether the installation site selected by the owner has been confirmed and authorized by the relevant on-site management departments such as the property;

Whether the installation point of the owner's charging box is equipped with power supply and meets the demand.

note:

If the power distribution is not satisfactory, you can choose to install the charging equipment for free first, and then entrust the power distribution personnel to connect the power when the owner distributes the power. You can also ask the service shop to install the charging equipment equipped with the vehicle for free after the power distribution.

3. The service shop and the owner agree on the time for on-site installation.

If the service shop does not meet the installation qualification, it will be outsourced for installation. At the same time, the owner will be informed that the door-to-door installer of the service is an outsourced person due to the influence of local policies or the qualification of the store, and specific information will be provided to the owner.

4. The service shop/outsourcing technician will install the charging equipment and connect the power supply.

If there is no power distribution, only charging equipment is installed.

Fourth, the installation is not standardized and misunderstanding shows.

1, extending the charging gun line without authorization.

2, external charging misunderstanding

note:

1. As shown in the figure, the trunk presses the cable, which will cause cable damage or node temperature rise;

2. The charging environment is humid, which is prone to charging short circuit;

3. The charging box is placed in the car. If there is a charging failure, the whole car will be burned.

3. There are potential safety hazards in high-altitude flight routes.

note:

1. As shown in the above figure, there is a charging safety hazard in overhead flying line charging;

2. The plastic shell of the external charging cover has potential safety hazards such as heat dissipation and short circuit when the charging rod is inserted into the water.
