Advanced kinetic energy recovery braking system, coupled with an existing internal combustion engines to create a new integrated electrified powertrain.
Optimizing the Combustion Engine
Volvo Cars are driven by a desire to make things better. Volvo's move towards electrification includes pre electric cars, plug-in hybrids and now mild hybrid propulsion systems which deliver a smoother driving experience and a new level of efficiency
A new generation of power
Mild hybrids offer an effective powertrain solution that actively reduces engine load, thereby improving fuel economy and improving the driving experience. A mild hybrid combines an electric motor, a 48 volt battery and a 12 volt/48 volt converter with an internal combustion engine. The electric motor acts as a starter to rev-up the engine smoothly. It also works as a generator, collecting energy recuperated by braking, which is stored in the 48 volt battery. This provides electric power to enable better acceleration.
Frequently Asked Questions
What is a mild hybrid?
A mild hybrid is also considered to be an electric car. Mild hybrids use both a combustion engine and an electric motor to reduce emissions and improve fuel economy. They does this by using energy stored in a 48-volt battery that is generated by braking. This energy is then used to boost the combustion engine during start-up and take-off.
Does the electric motor propel a mild hybrid?
No. The electric motor is there to assist the engine and to reduce the amount of work it needs to do.
What is the main benefit of a mild hybrid?
A mild hybrid will offer reduced fuel consumption and thereby lower emissions. Mild hybrids are generally more affordable than full hybrids or plug-in hybrids.
What is the difference between a mild hybrid, a full hybrid and a plug-in hybrid?
A mild hybrid uses the electric motor to assist the combustion engine. A full hybrid has a larger electric motor and battery than a mild hybrid. A full hybrid can power the car using the electric motor for short distances and recharges its battery using the engine or through regenerative braking. A plug-in hybrid can be recharged by literally plugging it into a home charging station or using a public charging station. A plug-in hybrid offers a greater pure electric range thanks to a larger battery pack and electric motor. A plug-in hybrid will meet the daily commuting needs of many people.
