  1. Battery Research Lead Acid vs. Nickel Metal Hydride

  2. Current Battery in Vehicle • Discover Clean & Green series • Absorbed Glass Mat (AGM) Valve Regulated Lead Acid (VRLA) • Low self discharge rates (Approx. 1%-3% per month at 20 °C–25°C / 68°F–77°F) • Battery packs total 144V • Weighs 89.5 lbs each • Weighs 1074 lbs total

  3. Minutes of Battery Discharge Performance Averages after 25 cycles

  4. Constant Current Discharge Ratings in Amperes at 20°C (68°F) • End Point Value: Voltage of the battery at the end of discharge period • The current discharge rating decreases as the length of time of the current discharge & the end point voltage increases

  5. Constant Power Discharge Ratings in Watts at 20°C (68°F) • The power discharge rating decreases as the length of time of the power discharge & he end point value increases

  6. Depth of Discharge Ratings • As depth of battery discharge increases, total numbers of times battery will successfully charge decreases

  7. Toyota Prius Battery • Nickel-Metal Hydride battery pack • Ni-MH are known for having high specific power, a high energy density, a long cycle life, and for being a low maintenance choice • Environmentally friendly • Total weight of battery pack is 118 lbs • compared to 1074 lbs in our 144V system • Power output of 36 hp (27kW) • Provides 201.6 Volts (Gen III & IV) • Panasonic Metal Case Prismatic • Since 2004 model

  8. Toyota Prius Battery • Feb 2011 - Prius has available in US for 10 years • Consumer Reports did testing to determine lifetime of battery and cost to replace it • 2002 Toyota Prius with over 200,000 miles on it compared to the nearly identical 2001 Prius with 2,000 miles tested by Consumer Reports 10 years before • Results: • Little difference in performance when tested for fuel economy and acceleration • Overall fuel economy of the 2001 model was 40.6 miles per gallon, while the 2002 Prius with high mileage delivered 40.4 miles per gallon • Effectiveness of the battery has not degraded over the long run.The cost of replacing the battery varies between $2,200 and $2,600 from a Toyota dealer, but low-use units from salvage yards are available for around US$500

  9. Toyota Prius Battery • Battery Details

  10. Toyota Prius Battery • Very little was changed for 2010 model • Slightly redesigned • Designed to last vehicle Life or up to 180,000 miles • The shortest life cycle occurs when the battery pack is stored at high temperatures for long periods of time
