| ISS (Idling Start Stop System) is a system that automatically stops the engine when the vehicle is brought to a standstill, such as at traffic light, and then reactivates the engine when the vehicle moves off again. Driving cars that use ISS, the battery needs to provide starting current to the vehicle and switching between charging and power current supplying much more often compared to a conventional engine running. Therefore, Hitachi has developed a battery that is durable with excellent charge acceptance and powerful current delivery to match the technological requirements and capabilities of these new generation vehicles. |
