 Jan 2025 - Battery management   Total loss system needs careful thought about energy storage during a race meeting and the necessary charging scenarios. The only approach is to estimate worst case. This system has three modes a) Monoposto running from 20AH Lithium M/C battery and expected duration b) Charging Monoposto battery from RV battery and c) Charging RV battery from the van starter battery during going home time.  Here is a table predicting the life of the M/C 20ah Lithium battery and RV battery (donor). AH = Amper Hours WH = Watt Hours. The table assumes the M/C battery is charged from the RV battery at some point in a two day weekend. a) Running from a M/C battery the table labeled LOAD shows 2 days running charging is expected after 10 runs from the RV battery. It is assumed 20 runs is a two day weeked and only loads the RV battery less than 50%. b) In the event of deciding to charge from the RV battery it must be done via a special charger that is designed fo...
