  • Patent number: 9893548
    Abstract: A battery charger is disclosed for use with various batteries, such as automotive- and marine-type batteries. In accordance with an aspect of the invention, the charging current is alternated between non-zero DC charging current levels. By alternating the charging current between non-zero DC charging levels, the battery can be charged to a higher capacity (i.e., ampere hours) faster, thus reducing the charging time and at the same time allow the rating of the battery charger to be increased. In accordance with another important aspect of the invention, the technique for alternating the charging current can be implemented in both linear- and switched-mode battery chargers.

  • Patent number: 9871275
    Abstract: A battery-state estimation device obtains, at a first timing, a first resistance value corresponding to a first open circuit voltage of a lithium-ion secondary battery and a second resistance value corresponding to a second open circuit voltage, which is higher than the first open circuit voltage, of the lithium-ion secondary battery. Further, the battery-state estimation device obtains, at a second timing which is different from the first timing, a third resistance value corresponding to the first open circuit voltage and a fourth resistance value corresponding to the second open circuit voltage. The battery-state estimation device determines presence or absence of lithium deposition in the lithium-ion secondary battery, based on a magnitude relation between a first variation amount of the third resistance value with respect to the first resistance value and a second variation amount of the fourth resistance value with respect to the second resistance value.
