I need some feedback on my assumptions here. If your are charging at 240 V 40 A for an hour, then your are using about 10 kW for the hour or 10 kWhr. This is what you get charged for by the electric utility regardless of how much is stored in the battery. The MS will slow the battery charge rate when the battery is getting full, but looking at the charging page, it still draws the 10 kW. So if your driving averages say, 100 miles per day, doesn't it make more sense to start charging when the rated miles are low, e.g. 20-40 miles and stop at 120-140 miles. This would be a cheaper charge than to charge it to 240 every night. Right or wrong or somewhere in between?
