Denso has developed a lithium-ion battery pack that its says further increases the fuel efficiency of vehicles with stop/start or micro-hybrid systems, allowing stop/start systems to use more regenerative power than single lead-acid battery systems. The battery pack consists of a battery management unit and power supply control switch, as well as lithium-ion battery cells supplied by a third-party.
Denso’s new battery pack supplies stored regenerated power to electrical and electronic components such as navigation and audio systems, reducing the power generation required by the alternator and resulting in an overall load reduction on the engine. The new battery pack is air-cooled, and requiring no dedicated battery cooling system, is relatively light and compact. Denso has also developed different types of starter to meet the specific needs of its OE customers for their stop/start systems, including the Advanced Engagement (AE) Starter, Permanently Engaged (PE) Starter, and Tandem Solenoid (TS) Starter. Denso has also developed a Cold Storage (CS) Evaporator which increases the effectiveness of idle-stop, particularly at high temperatures.
Denso supplies the lithium-ion battery pack, the TS starter and Cold Storage Evaporator on the Suzuki Wagon R, which launched earlier this month.
