how to install ev charger at home

How to install ev charger at home, full process guide

1. Preliminary condition verification and preparation

‌1.1. Property rights and property approval‌

Confirm the property rights or long-term use rights of the parking space (a contract of more than 1 year is required for leasing), and submit a construction plan to the property according to the "EV Distributed Charging Facility Engineering Technical Standards", including the meter installation point and line direction drawings, which must be approved by the property seal. Old residential areas need to provide additional fire emergency plans to ensure compliance with cable flame retardancy, leakage protection and other specifications.

‌1.2. Power capacity assessment‌

Apply for a new energy dedicated meter through the power grid company APP, and the system will automatically detect the line load capacity. If the residence is a single-phase meter, it needs to be upgraded to a three-phase meter to support charging piles above 7kW. Hongjiali charger supports dynamic power adjustment and can adapt to different power supply environments.

1.3. Equipment selection recommendations‌

Preferentially choose standard charging guns, and mainstream brand equipment must have 8 safety functions such as overvoltage protection and leakage monitoring. Hongjiali chargers are equipped with LCD touch screens and APP remote control, and support time-of-use electricity price settings.

2. Installation and implementation process

‌2.1. Meter application‌

Log in to the power grid platform and submit your ID card, parking space certificate, and property consent letter. The on-site inspection will be completed within 3 working days. The dedicated meter and the household circuit are measured independently to avoid excessive tiered electricity prices‌.

2.2. Line laying specifications‌

Use YJV type copper core cable (7kW requires 6 square millimeters, 11kW requires 10 square millimeters), wear galvanized steel pipe protection and grounding, and the height of the overhead line is not less than 2.5 meters.

2.3. Equipment commissioning and acceptance‌

After the charger is fixed, the response speed of the charging start and stop and emergency stop buttons needs to be tested to ensure that the waterproof level reaches IP54 or above. After the installation is completed, report to the property and submit the completion data on the power grid company APP at the same time‌.

3. Special scenario solutions

‌3.1. No fixed parking space scenario‌

Use the "nearby parking space sharing" mode, install a detachable charger (such as Hongjiali mobile model), and realize permission management through Bluetooth ground locks.

3.2. Insufficient power supply capacity

With integrated photovoltaic storage and charging equipment, Hongjiali's 5kW photovoltaic + 10kWh energy storage system can meet the daily average endurance requirement of 50 kilometers and reduce 80% of grid dependence.

3.3. Space-limited transformation

The column-type installation solution is selected, the equipment is 1.2 meters above the ground and occupies only 0.25㎡. Hongjiali's wall-mounted charger supports 90-degree rotation and is suitable for narrow parking spaces.

4. Cost and maintenance

4.1. Total cost composition: equipment fee (4000-8000 yuan) + cable auxiliary materials (50-80 yuan/meter) + construction fee (1000-2000 yuan), some cities can apply for a 30% subsidy;

4.2. Operation and maintenance points: Check the wear of the gun head contact every month and upgrade the firmware system every six months. Hongjiali equipment provides a 2-year warranty, and the fault response time is ≤4 hours.

Through standardized declaration procedures and technological innovation, the installation cycle of home chargers has been shortened to 7 working days. Choosing equipment with CQC certification such as Hongjiali can achieve safe charging and energy management optimization at the same time.
