There'll be a mode for harnessing energy released during braking to recharge the 48v battery and a "moving stop and start" function that can switch off the engine as you're slowing down, before the auto has come to a complete halt.
The EcoDynamics+ powertrain reduces Carbon dioxide emissions by supplementing acceleration with electric power from an additional 48-volt battery and extending combustion engine "off time" using a new mild-hybrid starter-generator unit. It can even deliver a "Moving Stop-Start" if there's enough charge in the battery.
The 48V mild-hybrid powertrain is the first new technology to be launched as part of Kia's wider powertrain electrification strategy.
The mild hybrid system is compact and can be easily incorporated into existing vehicles.
Kia is introducing EcoDynamics+ 48V mild-hybrid diesel engines to their United Kingdom range later this year in a bid to reduce emissions. When decelerating, and inverter switches the current of the motor, effectively turning it into a generator to top up the 0.46kWh battery. The introduction of the new 48-volt powertrain marks Kia as the first manufacturer to offer consumers hybrid, plug-in hybrid, battery-electric and 48-volt technology across its model line-up. The latter is connected to the diesel engine's crankshaft by a belt, and under acceleration, it provides up to 10kW (14PS / 13hp) of extra power.
The diesel mild-hybrid powertrain is compatible with both manual and automatic transmissions, and could be adapted for front-, rear- and all-wheel drivetrain layouts. And while debuting on a diesel engine, it will be adapted for petrol units.
Kia already has hybrid, electric and plug-in hybrid models on sale in the UK.
