Forgive me if this is the wrong place, this topic is going to be a bit unusual from the norm here.
I am bouncing around the idea of getting a prius hybrid car and adding a secondary battery pack and onboard charger to supplement the stock battery and increase the fuel economy. The kits go for 9-12 grand and want to do it cheaper.
Well, the car uses from what I can tell around 240 volts. From one website it seems the voltage varies from 213-260. I know to use batteries to give this voltage would take quite a few in the deep cycle kind and hundreds if little cells are used.
The idea I have is loosely based and reversed from the idea to use a prius as a UPS system. Basically in that idea online, someone used some diodes to hooked the cars battery in parallel to the battery of a commercial 240 volt UPS system. It has trays of 12 volt SLAs in the UPS system and the prius battery is hooked in parallel to it with diodes keeping the UPS battery power from going back into the cars battery. When needed, the car kicks on and recharges the cars battery and power goes to the UPS system.
My idea is to use a 240 volt inverter, put a bridge on it to the car battery input so its DC. THen use the needed configurations of batteries to power the inverter.
Next would be charging the batteries. I know some inverters double as a battery charger too.
What do you guys think? The supplement packs are rated from 9-15 kilowatts and are lithum ion batteries. I was thinking of using lead acid batteries.
