Vehicle emissions regulations for 2025 and 2030 are unlikely to be met by conventional vehicle technology as applied to most vehicles beyond small cars. Going to strong hybrid and pure electric power-trains involves considerable expense and delay and often totally new platforms. However, an intermediate technology has reached a very exciting stage where it can incrementally improve traditional power-trains by replacing the alternator with a reversible 48 V electric machine and adding a larger battery that is at 48V not the 12V of a car or 24V of a bus or truck though, for now, these is retained. Much more of the braking energy can be regenerated.
The electric machine can provide torque boost, facilitating considerable downsizing and down-speeding of the internal combustion engine. Call it the 48V mild hybrid. Not only will it definitely allow all cars, trucks and buses to meet the impending regulations, it can be incrementally improved with new parts such as electric superchargers, pumps, aircon etc. The improvements - new forms of which are being announced all the time - permit the 48V mild hybrid to have increased acceleration, quiet start stop, near-silent electric take-off and other improved driver experiences stealing the clothes of strong hybrids, all at less than half the cost and effort.
