摘要： A method for estimating a state of charge of a valve regulated lead-acid battery includes; an overcharge amount identification step of identifying an overcharge amount when the lead-acid battery is overcharged after an arbitrary reference time; an open circuit voltage acquisition step of acquiring an open circuit voltage of the lead-acid battery after the reference time; and a state-of-charge estimation step of estimating a state of charge of the lead-acid battery based on the acquired open circuit voltage and a correlation between an open circuit voltage and state of charge in which a rate of change of the state of charge with respect to the open circuit voltage is smaller as the overcharge amount from the reference time until an acquisition time of the open circuit voltage is larger.

摘要： A module-based framework evaluates designs of advanced start stop systems, particularly 12 V advanced start stop systems. The framework separates vehicle and battery analysis and uses a power profile to evaluate different designs of the vehicles and batteries. Particularly, the framework can evaluate different battery solutions and compare performances as a function of drive cycles, motor size, and electrical loads. In addition to modeling, actual batteries are tested for the same power inputs for validating performance differences. This framework identifies performance limiting components for determination of the vehicle system component optimization.

摘要： A vehicle includes an electric power converter, a power source, a detection circuit, at least one processor, and at least one memory. The electric power converter filters voltage ripple generated by the electric power converter. The detection circuit determines an unfiltered measurement of the power source and a filtered measurement of the power source and generates a differential signal by comparing the unfiltered measurement and the filtered measurement. Said memory stores instructions executable by said processor. The instructions causes said processor to determine a state of health of the power source based at least in part on the differential signal.

摘要： A battery type identifying device is capable of identifying the type of a vehicle-mounted lead storage battery. The battery type identifying device includes: a charge processing unit which, on the condition that the state of a lead storage battery has reached a prescribed state as a result of a reduction in the amount of electricity stored therein from a fully charged state, carries out a determination charging process of charging the lead storage battery for a prescribed time; an accepted amount acquiring unit which acquires an amount accepted by the lead storage battery in the period during which the determination charging process is being carried out; and a determining unit which determines whether the lead storage battery is a liquid-type lead storage battery on the basis of the accepted amount acquired by the accepted amount acquiring unit.
