Re: EV-Charge America EV2104: Complete Review!

I am just saying I would have waited until it failed to charge a vehicle and then utilize the warranty
The very last thing I would do is take it all apart and re-engineer everything

I am considering modifying my Leviton with a slightly longer power cord. This makes me think I will not order the Leviton until I have the LEAF to test it first right out of the box. I want to make sure it works before I open the case. Or I may make up a short extension cord to hopefully keep the 10 year warranty.
1 bar lost at 21,451 miles, 16 months.
2 bar lost at 35,339 miles, 25 months.
LEAF traded at 45,400 miles for a RAV4-EV
RAV4 traded in for I-Pace Dec 2018

Well, now we know why there's no UL approval, and it would look as if they're not anywhere near to approval; first one has to have a functional product! I wonder why they even bothered to ship you a unit which was, by design, non-functional? I doubt they'll be in business long if they try that stunt too many times...

How long before people will realize this company is either a scam or incompetent, I have been involved and EVs and EVSE units for over seven years and if you buy one of these you may as well charge back you CC before it arrives. Don't buy an EVSE from any company that is not established in the market, there have always been EV scams for years and there will continue to be so. I'm not even going to comment on the wire connectors in there.

Neat- so for those of us with a bit of electronics experience a chargeamerica with a modular ev power controller looks like it might be a pretty cool combo. What are the cababilities of the modular ev controller? Was it fairly straightforward to swap into the chargeamerica casing? Will it drive the LCD dispaly on the chargeamerica unit? looks like it's probably just a standard hd44780-compatible 20x2 display, so it seems like it should...

(edit) - nevermind, I see - they've changed direction and now instead of using LCD interface they will use serial... Does it still have the capacity to connect to a standard LCD? Do they have a software program for interacting with it via serial connection, or is it all hyperterminal?

Thanks for testing all this stuff!

Hello,
I don't think you can use (triacs) SS relays in an EVSE. Doesn't adhere to the J1772 standard.

Darkstar,

If your pilot is J1772 compliant (-12V to +12V 1khz) and your microprocessor analog inputs read from 0 - 5V you should be able to use the circuit below. The +5V input and resistors provide a voltage bias to keep the voltage at the analog input positive even when the pilot is -12V. At the analog input the -12V pilot will read about 1V and +12V will read 4.4V. To get your pilot voltage take your analog input voltage subtract 2.6V and multiply by 7.

Pilot Analog Input reading
-12V 1V
0V 2.6V
3V 3V
6V 3.4V
9V 8.8V
12V 4.4V
