We also decide to make a change in the software controlling regenerative
braking. We have two goals: To maximize recaptured energy and,
to allow the driver to use regen at the beginning of a race without
having to worry about over-voltaging the cells.
Our old set up was to limit regen to 280 amps and not use regen
for the first lap. We decide to allow the full 600 amps but use
the inverters to strictly limit voltage. We will start with a
low voltage and keep a sharp eye on the BMS voltage reports. We
will adjust the voltage limit upwards to make maximum regen.
do not yet have an optimum solution for charging at Moroso. The
shared 110 volt 15 amp outlets are inadequate for serious charging.
We can reserve 30 amp 110 volt outlets but even those will only
provide slightly less than 10 amps current into the pack. Our
main source of power is a Honda 5000 generator. This should provide
about 12 amps. Best case, it would take over 5 hours to charge
an empty pack. We will need to plan our power usage carefully.
