JAECOO 7 SHS: EV vs HEV mode and battery settings

Supported models and trims

JAECOO 7 SHS/PHEV: Luxury / Black Luxury SHS-P, and earlier PHEV versions with the described equipment; this is not an SHS-H guide

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

1. Park with the J7 SHS in READY.
2. On the February 2026 interface, open Audio System → Settings → Driving and select HEV, EV or EV+ as appropriate.
3. Alternatively, use the EV/HEV control in Control Center or the fitted EV/HEV knob. The handbook illustrates these alternatives; use the control actually installed.
4. Check the matching mode indication in the instrument cluster. A rejected request is not a successful mode change.
5. For battery management, open Audio System → Settings → New Energy and choose Initial, Smart or Forced power saving according to your needs.
6. If you choose Forced, check the target and whether its setting is memorised. The manual says a non-memorised Forced setting returns to Smart at the next power-on.

EV, HEV and EV+ explained

Which battery setting suits which job?

Initial allows more battery use and suits regular charging. Smart balances economy and retained energy. Forced aims to preserve a chosen battery level for later use, such as external discharge, at a fuel-economy cost. No universal target percentage is prescribed here.

Earlier PHEV interface

The October 2024 handbook selects modes using the EV/HEV button or Audio System → Vehicle Center → Quick Control → HEV/EV/EV+. It also says selecting Sport from EV changes the power mode to HEV. Do not assume that every menu or linkage described by that edition appears unchanged on the newer screen.

Other powertrains

These instructions cover plug-in SHS/PHEV, not SHS-H. J5 petrol and J7 petrol do not use this plug-in EV/HEV procedure. E5 is battery electric, so it has no petrol HEV mode.

Troubleshooting

• Cannot select EV: the battery level or other conditions may prevent it. Read the instrument-cluster message instead of repeatedly forcing the selection.
• Engine starts despite charge remaining: the manuals describe periodic engine self-maintenance after long electric-only use. HEV also starts and stops the engine as needed.
• Electric range changes: temperature, heating/cooling, driving style, hills and traffic affect the estimate. It is not a promised distance.
• Battery hold uses more fuel: forced battery protection prioritises battery level and the manuals warn that fuel economy deteriorates.

Safety and limitations

• EV mode is not a guarantee that a plug-in hybrid’s engine can never start. The handbook describes automatic engine self-maintenance and low-battery changes.
• Never leave a READY hybrid in an enclosed or poorly ventilated space. Do not use accelerator-triggered stationary generation as a casual charging tip.
• Choose settings while parked and monitor the actual mode indication. Drive smoothly and maintain sufficient fuel as well as charge.
