Vehicle-Integrated Battery and Power System Management based on Conductance Technology to Enable Intelligent Generating Systems (inGEN®)

This paper will present advanced battery monitoring technology developed for integration into the vehicle system to enable true battery power diagnostics and management. The paper discusses the necessary battery parameters to be measured and the diagnostics to be reported to the vehicle operator or system, including a methodology to accurately calculate true state-of-charge (SOC) and state-of-health for both cranking and reserve capacity for SLI lead-acid batteries. The resulting power management technology would provide continuous battery diagnostics for real-time power assurance. It would also provide measurements to enable optimized charging, effectively creating a truly intelligent and integrated generator system. Finally, the paper presents development and research data produced from a system already deployed in 14V vehicle battery applications (inGEN®), and introduces some initial requirements for deploying into a heavy-duty truck or bus application.
