Climate warming and rising gas costs drive demand for electric cars and plug-in hybrids. Each year, more EVs are released, providing drivers with additional alternatives.
2022 is a critical year for EV market growth and share. EVs and EV charging stations have unique qualities and issues that must be considered. We’ll discuss how power supplies impact EV charging station performance below.
EV Chargers
EV charging stations must supply continuous, stable electricity to recharge more EVs. 1 in 5 new automobiles produced globally will be electrified by 2025, and 2 in 5 by 2030. The hybrid and electric car sector has risen internationally, notably in India, according to FAME India. The worldwide EV charging stations sector is under pressure to provide more chargers that can provide continuous, consistent power for charging more EVs.
Charging stations may be AC or DC. AC EV charging stations offer AC electricity to the EV, which converts it to DC for its battery; DC charging stations give direct DC power to EV batteries.
AC level 1, AC level 2, and DCFC are the primary EV charging stations (DC fast chargers). AC Level 1 Chargers are inexpensive, simple, and compact. Most people use AC Level 2 chargers, and DCFC chargers are the most sophisticated and power-hungry. EV charging stations might be AC portable, wall mount, charging pile, or DC rapid.
AC/DC power supply is the system’s heart. There are numerous typical elements to consider when choosing AC/DC power sources for an EV charging station’s electric circuit. First, examine the charger’s compatibility with worldwide grid voltages. Voltage fluctuations may affect a power supply’s lifetime and performance when the grid voltage is unstable. First, check whether the power source has a broad input voltage range.
Electrical engineers should also choose an EV charging station power supply based on various criteria. The optimal power module for this application should be efficient, reliable, and resistant, preferably moisture-proof and anti-corrosive. So, EV charging station power sources are long-lasting and dependable.
Electrical engineers shouldn’t overlook temperature variations and extreme weather conditions, as EV charging stations are generally situated outside. In July, outside temperatures may approach 40°C, and the charger can reach 80°C. AC DC switching power supply must function across a broad temperature range.
EMC performance is also essential. Lightning may create a tens-kilovolt power spike. Despite several precautions, AC/DC surges may reach 1kV or 2kV. The inability to tolerate the surge will harm the AC/DC power supply.
Conclusion
Electrical engineers should choose a power solutions supplier for electric circuit design projects. Mornsun has 23 years of expertise in the power supply market and offers a variety of power modules.
