I came across an online report about "Reuse Of Old Batteries For Hybrid Cars(HV)". I would like to share and share some of the interesting points here. The big car company in Japan, Suzuki developed street lamps which emit by storing solar power energy on Lithium-ion batteries used for hybrid cars. They installed it onto city's facilities and started conducting a verification test collaborating with Iwata City in Shizuoka. Their aim is to reuse scrapped batteries and to prevent CO2 emission. That also will lead to improve car's value. 10 batteries are equipped in the 25 by 25 centimeter box. They are generated by solar panels and stored electricity. They turns on LED light. The battery system has no issue regardless of how the deterioration on each battery is different and is easy to replace each used battery with another one. One-hour charging on the system can store an one-overnight electricity. With full charging, the system can work for 5 days even if rainy and cloudy weather last. The city expects that the system enables us to save about $35 per year worth of electricity bill and prevent CO2 emission which a few cedar trees absorb. Suzuki is planning to install other city's facilities and apply to cameras which monitor river when disaster occurs. I think it is a good idea to consider the reuse of wasted depleted batteries and it is supposed to be very useful in the future.
