Frequently asked questions

How long does it take to full charge an EV?


This depends on the EV battery size, remaining battery capacity, and the type of EV charger used as well as environmental conditions such as temperature.

Typically, an AC charger with an output power of 7–22 kW can fully charge an EV in between 3 and 6 hours.

With a 50–200-kW DC fast charger, the charge time can be reduced to 10–30 minutes.




What’s the difference between AC and DC charging?


An AC charger provides AC power, which is then converted to DC power by an onboard charger inside the EV (before it reaches the battery). AC chargers are normally used in slow-charging applications such as home charging.

A DC charger converts AC power from the grid into DC power, which is more efficient and supplies the batteries directly. Thus, the charging time is markedly shorter. DC chargers have higher power requirements and therefore a higher installation complexity. As such, the installation cost can be higher than that for an AC charger. DC systems are generally used in commercial/public charging applications where shorter dwell tines are needed.




Does the AC charging connector fit my EV inlet?


To meet global charging standards, Delta AC chargers come with different types of charging connectors, including SAE J1772, IEC 62196-2 Type 2, and GB/T. These are global charging standards and will fit the majority of EV available today.

SAE J1772 is common in the United States and Japan while IEC 62196-2 Type 2 is common in Europe and South East Asia. GB/T is the national standard used in China.




Does the DC charging connector fit my EV inlet?


Delta’s DC chargers come with different types of charging connectors to meet global charging standards, including CCS1, CCS2, CHAdeMO, and GB/T 20234.3.

CCS1 is common in the United States and CCS2 is widely adopted in the Europe and South East Asia. CHAdeMO is used by Japanese EV manufacturers and GB/T is the national standard used in China.




Which EV charger should I choose?


This depends on your situation. Fast DC chargers are ideal for cases where you need to recharge your EV quickly, such as at an intercity highway charging station or rest stop. An AC charger is suitable for places where you stay longer, such as workplace, shopping malls, cinema and at home.

How do I install a Delta EV charger?


EV chargers must be installed by an certified electrician or authorized installer. Delta’s installation partners can provide technical consultations and quotations depending on the installation site.
