|2012 Chevy Volt|
When I purchased my 2012 Chevy Volt, I was aware that it came with its own charging cable that could plug into any regular 120 V outlet, but it would take almost 9 hours to fully charge the vehicle. Faster Level II chargers could reduce the full charge time to below 4 hours.
Since I wanted to track energy usage for charging the vehicle, I pulled some heavy wire (Romex 10/3) from a 20Amp 240V breaker out to the front of the building and installed a separate Watt meter that I found on eBay, and installed a 120V outlet below it to start with. (I read the meter weekly and post results to a chart on my web page.)

The installation was relatively simple:

The trouble began 11 months later just before the charging station went out of warranty. It stopped working and showed a red indicator light. So I returned it to Bosch and they sent a replacement. When it failed again a few weeks later I decided to open it up and have a look inside. What I found was that the engineer who had designed this charging station had installed fuses on the circuit board that were soldered into the board making them completely un-replaceable to your average consumer. However, as an electrical engineer it was relatively simple for me to remove and replace those blown 15 amp fuses with ones rated for 20A. The original fuses were rather conservatively rated since the Chevy Volt draws just below 15A per leg of the 240V line. In retrospect I think that my 240V table saw creates power surges that more than likely caused these fuses to blow. Here is a close-up of the circuit board inside the charging station:

I decided to install the charger inside and reuse the charger cable and plug from the original charging station. Here it is installed inside behind the Watt meter:

In addition to reusing the original coiled charging cord and plug, I also took the plug holder out of the old charging station and mounted it to the wall under my carport. This allows me to charge and store the connector in 2 locations which is convenient.

Here is my Volt being charged under the carport, and you can see the other charge plug storage location below and to the right of the Watt meter out front where I often charge the vehicle in good weather. I also put a 120V outlet on the left of the meter box for the Volt Charger.
