This is why you need to understand your home and what each appliance/system uses under normal conditions. Then you will know how much your peak hour demands are on a day by day basis. 10kW is still a lot of energy to use in a day unless you have storage headers.KEV777 wrote: ↑Thu May 21, 2020 2:47 pmYes agree using up battery life with more cycles will be a concern, but I guess you would only use EV battery to feed house energy requirements at night, not feed stored power back to energy grid. This would mean only a small percentage battery use each night, not a full cycle discharge & recharge. I would also imagine timing and usage parameters/limits could be preset. I can't imagine this type of use would substantially reduce life of battery? I would be happy to use say up to 10 kW from my battery each night if it meant no draw from grid and therefore no electricity charge from energy supplier. I would then recharge car during day once sun shining and utilise home PV or fast charger when out..win win!Abu Dhabi Dude wrote: ↑Thu May 21, 2020 1:46 pmI’m very reluctant to be an early adopter of v2g. It sounds like a wonderful idea, but I am very concerned about the increase in the number of charge cycles the car will go through. I would be worried about the level of degradation this would cause and the reduction in the lifespan of the battery pack. It may prove to be an unfounded fear but I would not like to be an early tester of it for that reason.
I have records of my home daily electricity consumption going back almost 9 years. I know what each run of the dishwasher takes, the washing machine, an hour of the top oven at 200C etc etc etc. One thing that people forget is the use of leccy by their gas central heating. It can be more than you think.
But even with 10kWh per day that is not a huge drain on the battery especially as it is spread over several hours. That's why I don't think it will have a great impact on battery life.
