3. Setup and Installation

Power Requirements:

This EV charger is designed for use with a standard NEMA 14-50 plug. It requires a Level 2 (220V-240V) outlet. Ensure your home is equipped with appropriate 240V outlets and a NEMA 14-50 socket. It is recommended to use a 40A circuit breaker for the 32A charger.

Initial Connection:

1. Ensure the car's handbrake is engaged.
2. Insert the charging head into the vehicle's charging port. You should hear a "clicking" sound, indicating it is securely inserted.
3. If charging a Tesla, first connect the included J1772 to Tesla adapter to the charging head, then insert the adapter into the Tesla charging port.

4. Operating Instructions

Charging Speed:

This 32A Level 2 EV charger provides a charging rate of approximately 30 miles per hour, depending on the vehicle model. The maximum power output is 7.68kW. For example, charging a Chevy Bolt EV (65 kWh battery) from 0% to 50% takes approximately 4.5 hours.

Adjusting Current and Timed Charging:

The charger offers 5 adjustable current settings: 8A, 10A, 13A, 16A, and 32A. For safety, the current can only be changed before charging begins. It also features a timed charging function, allowing you to delay charging by 2, 4, 6, or 8 hours. Setting it to 0H initiates immediate charging.

1. To adjust current or set timed charging: Long press the control button. Wait for the indicator light to complete the progress bar. The display will show options for current adjustment and timed charging.
2. Press the control button once to select either current setting or timer setting.
3. Long press again (wait for the indicator light to complete the progress bar) to enter the selected regulation or timer setting.
4. Press the control button to switch between current sizes or timed charging options (2/4/6/8 hours).
5. Press and hold again (wait for the indicator light to complete the progress bar) to confirm the settings. The screen will display "SUCCESS".

Delay Charging Function:

The delay charging feature allows you to schedule charging during off-peak hours, potentially reducing electricity costs. Once fully charged, the unit will automatically stop charging.

To cancel a charging delay time:

Unplug the charger for 2 seconds, then plug it back in to return to normal charging status.

5. Maintenance

• Keep the charging cable and connectors clean and free from dust, dirt, and moisture.
• Regularly inspect the cable for any signs of damage, fraying, or wear. Do not use if damaged.
• Store the charger in its provided storage bag in a dry, cool place when not in use.
• Ensure the charging gun tip and charging interface are clean before each use to prevent charging issues.

6. Troubleshooting

Common Issues and Solutions:

• Doesn't charge my car?
  1. Check if the car's handbrake is pulled in place.
  2. Restart the car, lock it, and then attempt to charge again.
  3. Verify the charging gun tip and charging interface are properly inserted. A crisp clicking sound indicates a secure connection.
  4. Check the charging interface of the car for any obstructions or damage. Reset if necessary.
  5. After attempting to charge, check if the car instrument panel shows any alarm faults or if the charging control box is functioning normally.
  6. If the charging station displays normally but the car is not charging, check if a delay charging time has been set.
• Why does the EV Charger feel a bit hot when charging?

  It is normal for the EV charger to feel warm to the touch during operation due to the current passing through it. The product has overheating protection. If the temperature becomes too high, the charger will automatically reduce the current to cool down. The current will automatically increase once the temperature has decreased. This is a normal protective function.

• The actual charging current is different from the description.

  First, verify that the correct current setting is selected on the charger. Second, confirm that the maximum charging power of your electric vehicle matches the set charging current. For example, if your vehicle only supports 13A charging, even if the charger is set to 16A, it will only charge at 13A.

Circuit Breaker Requirements:

Ensure your electrical setup meets the following requirements for safe operation:
