OREANDA-NEWS. Panasonic Corporation has developed a 12V Energy Recovery System for idle-stop vehicles that uses nickel metal hydride (Ni-MH) batteries for automobiles. This system allows the energy generated during braking to be stored in the batteries and use the stored energy to power the vehicle's electrical components, thus ensuring power availability even when the engine is not being used. In addition, as the system is designed to supply power to the drive assist motor as well, it helps improve the vehicle's fuel economy.

The system includes new Ni-MH battery cells developed by the company. Based on Panasonic's technology accumulated in the development of batteries for hybrid electric vehicles (HEV), the new battery cells offer higher charging efficiency and durability under high temperatures, compared to existing Ni-MH battery cells. That increases flexibility in the installation of the system, as it can be placed in the engine compartment which reaches high temperatures.

With a rising environmental consciousness, consumers are increasingly opting for eco cars such as HEVs as well as vehicles employing idle-stop systems in the pursuit of improved fuel economy. However, because conventional idle-stop systems depend on a single lead-acid battery to take care of all electrical needs of the vehicle, from restarting the engine to running the air-conditioner and other electrical components with the engine off, the battery is put under too much load. Panasonic's new 12V Energy Recovery System not only solves this problem but also improves fuel economy and extends the service life of the main lead-acid battery, thus contributing to increased functionality of idle-stop systems.
