Hyundai Santa Fe Mild Hybrid Spied Testing

During the 2018 Geneva Motor Show held on March, Hyundai has announced its plan to launch a new-generation Santa Fe Mild Hybrid, Hybrid & Plug-in Hybrid, and we have caught again the test mule of the first greener version to come of the successful SUV, the Mild Hybrid

After Kia announced its first Mild Hybrid model, the next model to add Mild Hybrid 48v technology will be the All-New Hyundai Santa Fe. No more details has been revealed yet, but we can said according to the latest reports, that Hyundai will offer first a mild hybrid variant, which consists on a 1.7 CRDi diesel engine (not confirmed yet, even on the Sportage) and a hybrid system with a 35 KW electric motor and a 48V lead carbon battery.

Kia Sportage Mild Hybrid System

Kia’s mild-hybrid technology features a compact 0.46 kWh 48-volt lithium-ion battery and a new Mild-Hybrid Starter-Generator (MHSG). By electronically controlling the MHSG using the inverter, the system switches seamlessly between two modes: ‘motor’ and ‘generator’. Connected by a belt to the diesel engine’s crankshaft, under acceleration the MHSG provides up to 10kW of electric power assistance to the powertrain in ‘motor’ mode, reducing engine load and emissions. In ‘generator’ mode, the system harvests kinetic energy from the vehicle during in-gear deceleration and braking and uses the power to recharge the batteries.

In other words, the Santa Fe Mild Hybrid equipped with the 1.7 diesel mild hybrid system will deliver 200 hp, like using the current 2.2 diesel and a fuel economy benefit of about 20% better than the average of the model.

The system is controlled by an advanced Electronic Control Unit (ECU), which calculates the most efficient use of the available energy, and adjusts accordingly, taking into account the amount of charge remaining in the car’s batteries.

Battery power can also be used to provide a new ‘Moving Stop & Start’ function. If the battery has sufficient charge, the combustion engine turns off automatically during in-gear deceleration and braking. The MHSG can then seamlessly re-ignite the engine – in any situation – if the driver presses the throttle pedal.

Stay tuned for further details.
