Q1. Who are we?

A: Our company " Shenzhen Huinengzhi Technology"

10+ Years Dedicated EV Charger Manufacturer (Established in 2014).

Over 1000 units deployed across Europe, South America, and Asia.

Independent Hardware and Software R&D with self-developed SECC controllers.

Q2. Do you test all your chargers before shipping?
A: All major components are tested before assembly and each charger is fully tested before shipped

Q3.what can you buy from us?
A: AC &DC EV charging pile

Q4. Can this 7kW charger be managed by a third-party white-label software platform?

A: Yes. With full OCPP 1.6J compliance, the charger allows operators to change the WebSocket URL via a local configuration web page or app, connecting instantly to any third-party CMS for billing, user authorization, and firmware OTA updates.

Q5: What are the installation requirements for a 7kW AC charging station?

A: A 7kW AC charger requires a single-phase 230V AC power supply with a current of 32A. It is highly recommended to install a dedicated circuit breaker (Type B RCD or Type A + DC 6mA protection) to ensure electrical safety.

Q6: Can a 7kW AC charger be installed at home?

A: Yes. A 7kW AC charger is the most popular choice for residential installations, as most household electrical grids can support a 32A single-phase load without requiring expensive grid upgrades.

Q7: Is a 7kW AC charger compatible with all electric vehicles?

A: Yes, it is compatible with almost all modern EVs and plug-in hybrids (PHEVs). However, the actual charging speed will be limited by the vehicle’s maximum onboard charger capacity (e.g., if a PHEV only accepts 3.5kW, it will charge at 3.5kW even when connected to a 7kW charger).

Q8: What charging interface standards do these chargers support?

A: Our charging stations can be configured with various global connector standards:

AC Charging: Type 2 (Europe), Type 1 (North America), GB/T (China).

DC Charging: CCS Combo 2 (Europe), CCS Combo 1 (North America), CHAdeMO (Japan), GB/T (China), and NACS (Tesla standard).

Q9: Are these chargers safe to use in the rain or extreme weather?

A: Yes. Our chargers are designed with high weatherproof ratings (typically IP54 or IP55 for outdoor use). They feature multiple safety protections, including over-current, over-voltage, short-circuit, leakage, and lightning protection.

Q10: Can I custom my LOGO?

Answer: Yes. You can not only custom LOGO, but also color, cable, enclosure box and carton. Just contact us if you have special needs. We accept full customization for Appearance/Software/Functions/ Accessories/Charging Standards/Packaging etc.

Q11: How long to fully charge a car?

To know how long to charge a car, you need to know the OBC(on board charger) power of the car, the car battery capacity, the charger power. The hours to fully charge a car =battery kw.h/obc or charger power the lower one. For e.g, the battery is 40kw.h,obc is 7kw, charger is 22kw, the 40/7=5.7hours. If the obc is 22kw, then 40/22=1.8hours.
