Getting ready to invest in this. The idea is to make kind of a hybrid for the electricity usage.
The idea is is to put a big lithium battery pack in the car to be able to run the car for 3 hours plus regenerative braking.
I found a very good deal on some 3.7v 43Ah lithium cells. But i must act fast.
I was thinking baybe 3S configuration that i will convert to 15V amd send to a capacitor array, and then directly connect it to the alternator for charging (assuming they can take all the alternator current).
A 4s configuration might be ok connected directly. But voltage may be too high to be fully charged. On the plus side if they are connected directly then i do not have to worry about the pack running dead as the alternator will kick in and not let the pack drop too low. Tje alternator signal would have to be tricked a little bit to get 16V output on regenerative braking to get some benefit.
Then there is the multiple in series configurations. 5s 6s ... 10s. Tjese would be used with a stepdown voltage regulator to constantly keep the capacitors at 16v.
