How to use JAECOO 7 SHS V2L external power

J7 SHS can supply standalone appliances through its AC charge port when external discharge is fitted. Both supplied PHEV manuals state a 3.3 kW vehicle limit. The newer handbook says the discharge device is purchased separately.

UK manual review; not a hands-on vehicle test. A missing menu may reflect equipment or software; this guide does not promise a feature can be enabled.

Before you begin

Park safely before changing settings. Match the powertrain, equipment and screen layout to the handbook for your own car. A manual describes possible equipment; it is not confirmation that every UK trim has it.

Step-by-step instructions

Park safely outdoors, select P and apply the parking brake. Check sufficient traction-battery charge and fuel; inspect the dry port and undamaged, compatible discharge equipment.
With the car in READY, open New Energy and switch External Discharge ON. The February 2026 New Energy overview places it in Charging/discharging management.
Open the charge-port cover and AC-port protective cover. Insert the discharge connector into the AC port and secure it.
Press the discharge socket/power-strip switch. The described adaptor has a steady red indicator when its socket is available; the car displays discharge information.
Use compatible appliances within the lowest vehicle/adaptor/outlet rating. Keep the car outdoors: the manual says its engine can start to recharge the battery while powered on.
When finished, disconnect the appliances. Turn External Discharge OFF on the head unit before removing the connector.
Press and hold the upper release button on the documented connector and remove it from the AC port. Close the protective and outer covers and store the device.

How much can it power?

The supplied manual states a vehicle discharge ceiling of 3.3 kW. Your usable limit is the lowest applicable rating of the vehicle, adaptor, individual outlet, cable and appliance connection. The vehicle figure is not a promise that a single UK socket can deliver it. Add the loads of every connected appliance and account for starting surges. Use the ratings on your actual equipment; this guide does not promise that a particular kettle, heater or tool is suitable.

Earlier PHEV handbook

The October 2024 manual describes the same basic connection and shutdown sequence, entering READY before switching External Discharge off. It describes a device provided with the vehicle, whereas February 2026 says to purchase it separately. Neither statement guarantees what was included with your car. Check your supplied equipment and order specification. The older manual distinguishes a red power-strip lamp from a red vehicle charge-port fault lamp.

Can the engine start?

Yes. The manual says that, with the vehicle powered on, low traction-battery charge during discharge can start the engine to generate power. Never use V2L in a garage or where exhaust could enter a tent, caravan, building or occupied enclosed space.

Troubleshooting

No output: check equipment compatibility, charge level, the on-screen discharge setting, secure connection and the adaptor’s own switch. DC charging and external discharge cannot be used together.
Output stops under load: switch off appliances and check their combined running and start-up demands against every applicable rating. Do not repeatedly reset an overloaded adaptor.
Plug will not release: disconnect the appliances, turn discharge OFF and follow the adaptor’s normal release instructions. Do not pull on the cable or use the charging emergency release as an improvised first step.
Cooling continues afterwards: the manuals describe automatic fan/compressor operation for battery cooling. A smell, smoke or fault indication is a different matter and needs attention.

Safety and limitations

Use a correctly specified, manufacturer-approved discharge adaptor and compatible appliances. Inspect the port, plug, cable and power strip first; do not use damaged, corroded, wet or loose equipment.
Use dry hands in a safe, dry location away from heat, fire, hazardous chemicals and lightning. Keep children away from the equipment.
Keep appliances out of the boot, away from tyres and away from underneath the front of the car. Protect the cable from crushing, pulling and trip hazards.
Do not touch electrical contacts, modify connectors, improvise wiring or connect the output to household wiring. These instructions cover standalone appliances.
Disconnect appliances and switch discharge OFF before removing the adaptor. Never force a locked connector; seek help if the normal release will not operate.
Stop using the system if you notice unusual heat, smell, smoke or a fault. Do not dismantle equipment; contact the retailer.
This is a plug-in-hybrid procedure. It does not apply to the petrol J7 or establish V2L support for SHS-H.
