i-ELOOP DECELERATION REGENERATION [SKYACTIV-D 2.2]


id0180q1001900


Purpose of Adoption

•  For improved fuel economy, electrical power is generated instantly using kinetic energy during deceleration and retrieved as electrical energy, which decreases the amount of fuel used for supplying power (approx. 10%).

Service Point

•  Systems with different power voltage exist. In particular, when performing removal/installation of parts with power voltage between 13 V and 25 V (capacitor, DC-DC converter, generator), always disconnect the negative battery cable and remove the safety plug of capacitor.
•  After replacing the capacitor and connecting the battery, the i-ELOOP system enters the pre-charge mode because the capacitor requires charging, and a warning is displayed indicating, "i-ELOOP charging. Do not drive. This will take less than 3 minutes." Do not drive the vehicle until the warning light is turned off (capacitor is charged).
•  Because the capacitor cannot be examined using a tester or the i-ELOOP system, examine it visually, (damage to capacitor unit, capacitor connector damage/loss, corrosion).
•  Store the capacitor in an upright position. However, the capacitor may be tilted for short periods during assembly.
•  If the capacitor is dropped and danage or deformation is visible, replace it with a new one (no damage or deformation visible)
•  The service part is delivered with a short wire installed to prevent static charge. Remove the wire before installing the part to the vehicle.
•  When jump-starting the vehicle due to battery depletion from leaving the vehicle undriven for a long period, the i-ELOOP system will be in Pre-cahrge mode. While pre-charging mode, do not disconnect the jumper cables until the message indicating "i-ELOOP charging. Do not drive. This will take less than 3 minutes" is turned off.
•  For battery depletion other than when the vehicle is left undriven for long periods, pre-charging does not occur. After starting the engine, the jumper cables can be removed.
•  For vehicles with a capacitor and having the following sticker adhered to the top of the bumper (actually the sticker is hidden by hood so it is not visible when hood is closed) perform electrical discharging of the capacitor before disposal using the discharge resistance box. After discharging, dispose of the capacitor the same as other parts.

Common Inquiry

•  If the i-ELOOP system goes into bypass mode due to current consumption being 50 A or more or the ambient temperature is extremely low, the indication (power regeneration gauge) of the charge amount for the capacitor voltage does not change compared to when the system is in regeneration mode.
•  With the capacitor fully charged, the change in the indication (power regeneration gauge) decreases because the power regeneration amount decreases.
•  If extremely low or high temperatures continue, the indication (power regeneration gauge) may not change because power regeneration during deceleration does not occur.
•  If the capacitor voltage is low due to the vehicle being left undriven for a long period, the system goes into pre-charge mode and a warning stating, " i-ELOOP charging. Do not drive. This will take less than 3 min." is indicated.
•  This mode charges the capacitor due to a lack of sufficient power supply to the vehicle, and therefore do not drive the vehicle until the indication is turned off after the power supply is restored ( capacitor is charged).
•  There is no on/off function for the regeneration system because there is no need for turning off the power regeneration system.
•  If the vehicle is driven during the pre-charge mode, a warning beep is activated.
