Zencar 3-phase 22kW charging cable

PROS: control of power with RFID.

CONS: No bad PE protection detection (dangerous!), thin circuit board & bad design of PE line (risk of fire or burn), IP54 (moderate liquid ingress protection). No seal inside the plug.

  • ❗ Security
  • ⭐⭐⭐ Quality
  • ⭐⭐⭐ Functionality
  • ⭐ Value for money

1. Specs

Type2, 3-phase, Current: 10-32A (230Vx3), 3-phase IEC 60309 plug (red)

Manufacturer: Zencar China

Cable length: 6m

2. Security

Waterproof: IP54: ++ YES (Water splashing against the enclosure from any direction shall have no harmful effect)

Bad PE (protection) detection: – NO (car charges without PE line !!!)

Manual stop button: ++ YES (via RFID)

3. Accuracy

Real Charging Amperes: 31,58A ( 1,5% less than declared, so accurate)

Real Charging Power: 21,4kW

4. Controls

LED: Power, Charging, Charging Fault

Buttons: – (but RFID control for stop and power)

5. Quality

Connectors: silver coated

The EVSE is rigid. It has an informative screen with all of the important parameters. It is declared in manual, that it has bad PE detection, but we have proven, that it is not working.

hello Manager

good day, this is Andy from ZENCAR, I saw your web from fb.

thanks for you cost time to test our product and give us more good feebback. I want to talk with you some thing:

1. Not use PE protection: Because some custome’s socket not have PE protection, if we add this, there will be can’t charging, so we cancel this.

2. May I ask which AMP you test our product. Because i saw the relay was broken, that accept max 50AMP.

Looking forward to your reply and welcome to give us your suggestion.

Thank you very mcuh

Hello Mr Andy
1. PE protection is obligatory in the EU and selling EVSE without bad PE detection is illegal. Thus, Tesla solution works perfectly. Your product is simply illegal in Sweden, so also in Europe.
2. I must ask an engineer, but I assume, that power was standard (22kW). Broken circuit boards seem to be a collection of failed EVSE along years. I have asked to remove these photos as unfair criticism, so we leave only a piece of information about no bad PE detection. Generally, it seems, that the only one junction generates too much heat, because of the thin copper layer. Subsequent behaviour is that relay overheats (because of heat coming from the bad, overloaded junction) and blows. So it is not too high current, that causes a relay to fail, but heat and a general overload of a side-located junction.
We decided to scan your PCB design for general protection level, also with hi-res thermal imaging, so I will inform you (of course as a private message), what other design solutions may be improved.
