I was curious if anyone has came up with a charger for their HV battery pack yet? Seems that it would be a pretty simple device and I wonder why there are so few for the dealers. I haven't got to look at schematics, but from what I've read in the posts the HV batteries are disconnected when the car is powered down. If so couldn't you make a full wave rectifier for a 240 volt AC plug that puts out a low current for charging? I know it's a 255 volt battery pack, but 240 volt seems close to the 90% charge where it's supposed to charge up to. I wouldn't even need anything fancy, a timer could turn it on and off so there isn't anything too sophisticated.

I know I could benefit from a charger. I drive about 23 miles to and from work and the last three miles when I get home depletes the battery's charge. If I could start off fresh each morning it would definitely help my mileage. I've already installed an engine heater to help out this winter.
