High speed (above 40 kmph) reduce the range ofĮBike so it drain the battery faster, also it increase the copper Motor stator coil, as we supply the power in the stator coil, due to copper loss/eddy current loss, stator coil temperature also increase suddenly, so we have to keep this also cool. Mosfet, due to high speed switching / regenerative braking / high current flow, the temperature increase suddenly, so we must need cooling. This cooling is done in the price of reduced range, yeah we're using the power for cooling equipments from same battery, better we have to use the temperature sensor data to ON/OFF the cooling equipments, if we kept the cooling equipments always ON means, resulting in low range of eBike. In Lead acid battery, even after discharge, it keep the voltage same, but in capacitor half discharge means, voltage also reduced by half.ĭue to the heavy current flow in Motor stator winding and MOSFET, there is a possibility of damage beyond certain temperature, so we have to cool it to maintain below optimal temperature. Normal Lead acid and Lipo batteries capacity calculated in Ah, VĬapacitors /Supercapacitors capacity calculated in Faradįard to Ah conversion (for theorital understanding only): Height (including studs) 6.53 inches (130 mm)

Maxwell BCAP3000P 3000F 2.7V Super Farad Cap Ultra CapacitorĭC Equivalent Series Resistance (ESR) 0.29 milliohmĪC Equivalent Series Resistance (ESR) 0.24 milliohm Ultrabattery Lead acide battery and supercapacitor hybrid is ultrabattery, that is it improve the lifecycle/efficiency of lead acid battery, also improve faster charging/discharing. Supercapacitors store 2700 F, and charge in few seconds, but only contraint is weight, 15w-50w/kg Yeah, but battery technology improving these days due to intense researchs,Ĭonventional Batteries (we're using, also in production) : As we all know, Motor rating is fixed, and only thing that affect the eBike or car range is, BATTERY.
