Power Supplies
for EV Chargers
Global initiatives to reduce carbon emission and ESG management practices have transformed the automotive industry from internal combustion engines to electric vehicles, and the pace of growth continues to accelerate with the advent of autonomous driving.
While the global market for EVs is showing rapid growth, the infrastructure for EV charging, especially rapid DC charging infrastructure,
is still in its infancy. The majority of EV charging infrastructure still remains in the form of in-vehicle or slow charging. Thus, the slow movement towards building rapid DC charging infrastructures hinders the advancement of the automotive market and limits ultimate convenience.
As a consequence, most countries are establishing government policies to introduce ultra-fast charging system for EVs.
The core technology of the ultra-fast charger for EVs rests with optimizing the charging speed and efficiency by connecting multiple high-output (>30KW) power sources in parallel in order to optimize charging efficiency corresponding to the battery charging requirements and various charging conditions of EVs.
Y2 Solution is a leader in developing ultra-fast charging power supply technology for EV Charges, by utilizing 36 years of experience in power R&D and technology including digital control and communication technology.
