Hello...
I will try to answer all questions here.
- Space/size/weight is not a problem..
- Due to Kw/Km we determine that 78 Kw battery pack should be enough.
- The motor we will use needs 300-750V operating voltage. Max. current 615Adc, continuous of 350 Adc both @500Vdc. We don´t expect to be using all the power, but we want the battery to be able to provide it just in case. We thought a 100AH battery with 3C constant and 10C pulse battery should be fine.
- Expected cycles would depend on battery manufacturer and SOC. We would like to get around 5,000.
- We guess it will need active cooling.
Application
- We need it for a Bus, with this you can assume it will do constant starts and stops. From 0 to 60km/h will take around 22 sec., then cruising speed for 20sec. aprox. then stopping and waiting minimum for 12 sec. while loading and unloading passengers and start again. That would be constant for 1 hour at least. Then we expect the battery to be gone.
- we are intentionally looking for the smallest battery we can put together to reduce cost to the max. It doesn't matter if we have to charge it every hour or so, that is part of the plan. We don't want a 300Kw battery that will cost hundreds of thousands of dollars that will last all day and take all night
to charge. We don´t now yet if we will stop the unit for fast charging or if we will replace the pack to aloud the unit to keep running and provide 0.5C charge to extend battery life.
Thanks
