Theme: 48v automated Power Supply Sources. Plan 48 volt: what it is and why it’s important

MHEV is one way 48V can be applied to your hybrid design, with a number of supporting components available from Dalroad.

Proving a Point with TCO

If there is no total-cost-of-ownership benefit, fleet owners are less likely to electrify their vehicles. With impending regulation on fossil fuels, MHEV is one such way that manufacturers are proving the success of 48V for fleets; as a system capable of running EV components, without higher costs (thanks to aforementioned control in currents).

Keep in mind the benefits are different depending on the duty-cycle. For on-the-road Class 8 trucks, benefits are primarily in controlling the air compressor, steering pump, and other auxiliaries, turning them off when not in use.

Alternatively, if you are designing for a Class 6 delivery truck, with many transients, and starts and stops, the 48V system would be used for cooling systems, keeping engine temperatures low.
