DC EV charging power supply
Advancing electrification with fast charging
With electric vehicles (EVs) now viable alternatives in some markets to traditional internal combustion engine vehicles, the demand for enhanced power supplies for charging stations is growing. Currently, all eyes are on China where EVs have gained traction in the rapidly-expanding middle class. And the United States is expected to follow suit soon as well.
But for these markets to truly welcome EVs on a large scale they need widespread availability of DC charging infrastructure, so drivers can charge quickly. DC charging stations are an attractive choice because they allow for much faster charging than a standard AC EV charging pile, which many EV drivers have at home. Today, a DC charging pile with 120kW can charge around 80% of an EV’s battery in just 30 minutes. As these fast charging technologies improve, the charging time will drop even further.
Challenges on the horizon
Of course, designing a successful DC EV charging power supply presents engineers with a host of new challenges. For a DC power supply design to be a long term success you must:
- Enhance its output power to shorten the charging time
- Boost its power density, within the set dimensions of the charging station
- Increase its efficiency by boosting the load and decreasing power dissipation
Simultaneously, you must also find ways to reduce your design’s cost per watt. Overcoming all of these matters is possible – with the right partner.
