Honda civic hybrid mattery packs. Additional batteries?

[counterbond]

Can you add more batteries to the civic hybrids to make the gas mileage even better?

I'm not qualified to answer the question of if you can add more battery capacity to the Civic, but it wouldn't do much to improve the mpg of your car unless you could charge the batteries from an external source.

Charging batteries from power derived from your engine, and then using it to accelerate your car is less efficient than just using the engine to accelerate your car. The thing that makes a hybrid efficient is that it recaptures a small part of the energy that is normally wasted when you step on the brake; energy that is normally entirely wasted to heat.

I'm sure the Civic was engineered with a battery capacity that optimizes fuel economy, longevity, cost, weight and all of the factors that must be considered.

Now, adding battery capacity that can be plugged in and charged is a whole other topic, and I don't know how difficult it would be to adapt to the Civic.

I would say somewhat yes to your statement. I am sure their are HONDA forums where a more detail specific response could be made to your inquiry. My understanding most Honda IMA vehicles have a traction battery and therefore could be supplemented. The method process to do so is based on your choice of additional energy storage setup. You could get a local salvage yard traction battery similiar to your current vehicle or see if other options are do able..........

Honda Insight owners where doing some of this .... I would suggest search forums related and do some more homework.....

If you research the history of the HCH you will see Honda tried just that and it lead to ima battery failure. They went to an even smaller pack for the 2nd gen insight and crz. Now that honda has gone lithium they have increased the size for the crz and the latest hch even adding an EV mode to the hch.
