The big toaster

"I still don't think you understand how it works"- vendor email



After my onboard charger's spectacular death, I began researching alternatives. The vendor of my original charger is a private individual who builds them in his own shop, no assembly line, no "customer service" department. I emailed back and forth with him for a while and gave up on him.


First of all, he's convinced that everyone who buys his product is an idiot and that if his charger fails, it's automatically the fault of the user. I can understand how he came to be this way. After all, he constantly gets email and phone calls from people who don't know what a voltmeter is. I -understand- how he got to be this way, but I don't -condone- that attitude. Basically what I got from him is that he's too busy building new units to repair mine anytime soon. At $1550.00 for a new one, I started looking for a cheaper, simpler alternative.


The Zivan NG3 charger is "EV's for Dummies". It's built in Italy. You send the vendor your battery specs and they program it for you. You install it in your car and that's it. No adjustments, no hassle. I picked the 110 volt 15 amp version. It'll charge the car more slowly but I can plug in to any 110 VAC outlet and not worry about tripping someone's circuit breaker. This means flexibility. After all, when you look around, just how many 220 volt laundry dryer outlets do you see around? Not many.

My new charger arrived in a week. It cost me $950. Yes, the price of EV components sucks but they're supposed to last a long time. IF you design the car correctly that is. I made damn sure that the cowl vent was sealed up tight before I put the new charger in. No more rain water intrusion. The new charger doesn't have some of the features of the old one like multi-voltage inputs, adjustable amperage output, blah blah blah. I never used those features anyway. Still, this charger is very "smart". It's computerized and automatically turns off based on the battery's condition, not just a timer, it can tell if the battery pack is disconnected, it will shut off on an over voltage or under voltage condition from the wall AC voltage or the battery DC voltage. It has a single LED and gives a variety of beep codes to help you understand what's going on.

In the EV photo album, it seems to be one of the more popular choices. You can check all the other cars that use the Zivan charger here: http://www.austinev.org/evalbum/index.html

I've been running it since the beginning of April without a hitch. Just plug it and forget it, like a big toaster.
