With each passing year, new cars get more complicated and high-tech. The new higher power requirements associated with these advancements—along with ever-stricter emissions regulations—are why 48-volt electrical systems are spreading like wildfire, with experts expecting the tech to make its way into one-fifth of all cars sold globally by 2025. That’s a huge figure, but this technology isn’t exactly new. Here’s how it works.

When people talking about EV, they often are thinking about high voltage batteries around 400V that take a lot of space and weight in the vehicle. In reality, all-electric EVs have a lot of limitations and likely will only be a small % of the total vehicle market in the next 10 years despite we keep hearing a lot of news about it. What really is taking off is the 48V based mild HEV. It only uses a shoebox-sized 48V battery coupled with a bi-directional DC-DC converter that bridges this 48V battery and the traditional 12V battery. The change to the traditional gas-engine cars are very little, but it provides the means to assist the start and recovers the energy to the 48V battery during braking or even cruising. In addition to passenger vehicles, 48V battery system are also used in other kinds of moving equipment such as golf carts. Developing bi-directional, non-isolated 48V to 12V DC-DC in a few hundred watts to a few thousand watts will be a smart move to get ready for upcoming opportunities.
