Last Sunday I was charging the car and pulling about 27 amps. The charger should be able to pull 30, but quickly goes into a limit mode due to temperature. This happens no matter what the temperature is, and is just a flaw in the charger. It might happen due to the voltage of the car: the car runs at 154 volts, but charges somewhere higher, like 170V – I\u2019m not sure as the exact voltage as the charger has no measurement for this and you turn a dial to adjust it. So, it is stepping down the 220v input to 154v. And, I know the charger is only about 80% efficient, so the extra energy has to go *somewhere*, and that somewhere is heat dissipation.\u00a0<\/p>\n
The charger has failed several times:<\/p>\n
First time:\u00a0May 2011 – Charger Not Charging<\/a>\u00a0\u2014 Manzanita Micro repaired it (out of warranty) for $170. I wasn\u2019t quite clear on why it failed.<\/p>\n Second time: September 2012 – Charger Failed again<\/a>. – $213 to repair it, and they said the reason was from corrosion on the cables.<\/p>\n This time, I\u2019m seeing the same symptoms as the first time; the charger is causing a ground fault, and flipping the circuit breaker that my EVSE is hooked up to (50amp breaker).<\/p>\n I opened the box..I think the bad part is underneath where I can\u2019t see. It smells like magic smoke.\u00a0<\/p>\n I don\u2019t have much choices for a replacement charger; it is by far cheapest to just get this one repaired, so I\u2019ll send it back and have them fix it again. The EMW<\/a> charger looks nice; it outputs 12Kw, and is a decent price ($2300) \u2014 but I can\u2019t fit the 12x12x12\u201d dimensions in my current location. And I don\u2019t want to pay $2300 for a new charger, when I can get the current one repaired for a lot less.<\/p>\n![\"IMG](\"http:\/\/www.corbinstreehouse.com\/blog\/wp-content\/uploads\/2015\/07\/IMG_45131.jpg\" "\\"IMG_4513.JPG\\"")
