Abstract: Delivery Truck/Bus Hybrid Vehicles, experiencing frequent starts, rapidly load their batteries with pulse surges during the first hundredths of a second of acceleration. Traditionally, battery life is maximized by minimizing initial discharge pulses and sustained discharge rates, with initial surges two to three times battery capacity (2C to 3C). Early Lead-acid or Lithium-ion batteries in hybrid buses with 3C discharges had their life expectancies reduced 50-75%. Recent “Lithium Ion/Nano Phosphate” batteries reportedly increase durability to 100C. If these 100C expectations are not met, battery life can be extended with a capacitor bank “floating in parallel” with the hybrid batteries. This helps dampen acceleration surges, as well as initial charging energy impulses, which extends battery life.
