How the Super Hybrid System Works

Your J7 is a plug-in hybrid (PHEV). It can be driven by petrol, by electricity, or by both together. You get electric driving for everyday trips without worrying about running out of range, because the petrol engine is always there as back-up.

The main parts

• Power battery – a liquid-cooled lithium-ion high-voltage battery under the floor (18.316 kWh, 339.2 V rated). You charge it mainly by plugging in.
• Electric drive – the motor drives the wheels on its own or alongside the engine. It also acts as a generator when you brake or coast.
• 1.5 TGDI petrol engine – can drive the wheels directly, help the motor, or run a generator to top up the battery.
• Dedicated Hybrid Transmission (DHT) – the hybrid gearbox that combines engine and motor power. The car is front-wheel drive (2WD).

How it decides what to use

The car chooses the best energy flow by itself (see Energy flow). You can influence it with three controls:

• Power mode – EV, EV+ or HEV (EV/HEV button or Quick Control).
• Driving mode – Eco, Normal or Sport.
• Power saving mode – Initial, Smart or Forced, which decides how much battery charge the car keeps in reserve.

When the battery has plenty of charge, the car switches to electric (EV) mode automatically when you start it. Jaecoo recommends using EV mode whenever you can. When the battery runs low, the car switches to HEV mode by itself.

Ways the battery gets charged

• Plugging in to a home socket with the supplied portable charger, a wallbox/AC charging point, or a DC rapid charger.
• The motor recovering energy when you brake or coast.
• The engine generating electricity while you drive, or while parked (forced parking power generation in HEV mode).
