Looking for 20 Kilowatt Hour battery system

Does anyone have experience or located a 20 Kilowatt-Hour battery system for the Prius?

 

Finding the batteries is only part of the issue. You need the charge controller and the electrical engineering to push electrical current to appropriate storage.

Does anyone have true engineering data on the charge cycles and lifetime storage capacity of these batteries when cycled 400 times in a year and in all climates?

The chemical battery seems to be the strongest possibility at unseating gasoline, but internal combustion is still a very cost-effective, albeit carbon based, technique.

Please post your info.

 

Sounds like you would lose the entire "trunk" space in the rear of the passenger compartment. Collisions (either front or back) could be a big problem if the mass is 1000 lbs.

I may need to pare back my expectations to 10 KWH. I note that if you are buying 21 KWH of storage, you are essentially deep cycling the cells which limits lifetime.

My guess is that 15 KWH of storage actually equates to 10 KWH of actual cycling... is this the capacity of the systems being installed?

 

Thank you for the response.
I appreciate the data because this is about physics, albeit complex when calculating the rates.

Unless the manufacturers specify the exact characteristics of the vehicle, it is hard to evaluate the likelihood that the purchase matches need.

It is one thing to use Hybrid to recapture energy on braking, it is a completely other dynamic to begin to extrapolate the use of the car to other functions than just driving.

V2G is an exciting application.

 

The V2G solution would appear to add tremendous functionality and flexibility for the owner of the car.

By adding 20 KWH of onboard power storage, there is a capability to not only drive the vehicle a longer range. It would be able to power a small camp at night.

KWH of storage would translate to about 750 watts of power per hour of continuous discharge for one day.

That should be enough power to operate a small on-board refrigerator or freezer unit and associated electronic gear/satellite phone.

I suppose one would not need a Prius to make this solution because you could make it for any vehicle.

However, the Prius is particularly attractive due to the ability to extend range and store electricity.
