Major purpose of this thread is to understand the S-ENE CHARGE vs eNe-CHARGE vs IDILING STOP.

ISG (a generator with a motor function) generates electricity by utilizing deceleration energy and charges to lead-acid battery specially designed for vehicles equipped with Engine Auto Stop Start System and lithium-ion battery specially designed for vehicles equipped with S-ENE CHARGE. By assisting the engine with a motor during acceleration, where more fuel is needed, it realizes further fuel efficiency. Also, because the starter motor of the ISG (a generator with a motor function) restarts the engine through a belt after the engine auto stop, it is free from gear engagement noise, so it realizes silent and smooth restart of the engine.

Efficient generation through increasing the generation efficiency and utilizing the deceleration energy. With the combined motor function, it enables restart of the engine and assist of the engine with a motor during acceleration

Specially designed for vehicles equipped with S-ENE CHARGE, it complies with high current needed for the motor to assist the engine, which enables frequent assist of the engine


Suzuki's eNe-CHARGE system uses a high-efficiency, high-output alternator to generate electricity using the deceleration energy that is available every time the driver releases the accelerator pedal and every time the driver presses the brake pedal. The system stores the electricity in a lead-acid battery that is specially designed for vehicles equipped with Engine Auto Stop Start System and in a high-efficiency lithium-ion battery. It uses the stored electricity to power electrical equipment such as the car's audio system and meters. It thereby minimizes the amount of petrol used by the engine to generate electricity.
High-efficiency lithium-ion battery

The lithium-ion battery is light, compact, and highly efficient. The high efficiency with which this battery stores electricity enables the system to minimize the amount of electricity generated using engine power while the engine is propelling the car. The result is lower fuel consumption.

When the system starts generating and storing electricity during deceleration, the eNe-CHARGE indicator lights up in the meter cluster to inform the driver.
Suzuki's new Engine Auto Stop Start System limits unnecessary petrol consumption by shutting down the car's engine during deceleration. In the Suzuki Wagon R, it automatically stops the engine when the driver is pressing the brake pedal and the vehicle speed drops to 13km/h or lower. By maximizing the durations of engine shutdown, it helps to maximize fuel savings. The driver can restart the engine by just releasing the brake pedal or turning the steering wheel. Even at junctions, standing starts are smooth. An Engine Auto Stop lamp comes on in the meter cluster to show when the system is active, thereby warning the driver of impending engine shutdown. Also, the system has a hill-hold function that promotes peace of mind for the driver by helping to prevent the car from rolling backward during standing starts on hills.
In certain conditions, the Engine Auto Stop Start System does not operate even when the Engine Auto Stop lamp is on.
The driver can disable the system by pushing an Engine Auto Stop OFF switch. Also, the driver can use the switch to restart the engine when the system has shut it down.
The audio and other electrical systems can still be used when the Engine Auto Stop Start System has shut down the engine. If the air conditioner is running when the Engine Auto Stop Start System shuts down the engine, the climate-control system switches to fan-only operation. If the cabin temperature subsequently rises, the Engine Auto Stop Start System restarts the engine and activates the air conditioner to keep occupants comfortable.
The Engine Auto Stop Start System operates only when certain conditions are satisfied.
