Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

True on summer or over 25 celsius battery.. so its not happenin on 6 months here near arctic circle. . No indoor place for car. Still it might do some fan blowing for battery on winter if over 60a fast charge. Below 60a it wont use AC compressor even on summer.
