  • Patent number: 7964300
    Abstract: There is provided a risk-free and easy-to-use battery pack using battery cells 1 as a secondary battery, in which internal gases evaporated by applying overvoltage or the like thereto are processed inside a case to be prevented from leaking to the outside of the case and thereby even if the case has been led to rise in pressure due to a thermorunaway of the battery, the case is free from breaking. To realize this performance, the battery pack 10 is provided with a battery cell housing 17 for housing lithium cells 1 and a gas processor 15 for liquefying the internal gases g generated from the lithium cells 1.

  • Patent number: 7939192
    Abstract: A battery module for use in an electric vehicle is disclosed. The battery module includes a plurality of cells arranged in a predetermined pattern within the module. The battery module also includes an optical pyrometer arranged inside the module. The optical pyrometer is installed within the module after being tuned to detect a predetermined frequency or band of frequencies. The pyrometer will be used to detect an increase in short wave radiation density from one of the battery cells within the module wherein that battery cell has a temperature above a predetermined threshold. The optical pyrometer will be used to communicate an electric signal to a control system of the electric vehicle wherein that control system will implement a predetermined mitigation process to contain the thermal event of that one cell within the battery module.

  • Patent number: 7169504
    Abstract: A sulfonic acid type organic surfactant is incorporated into the gelled anode mixture of an alkaline electrochemical cell, optionally with an organic phosphate ester surfactant. Zinc fines may also be incorporated into the anode. The electrolyte included in the anode mixture may have a reduced hydroxide concentration. When a cell is provided whose anode mixture includes the two surfactants and zinc fines alone or in combination with a lowered hydroxide concentration in the electrolyte, discharge leakage is reduced and gel gassing is suppressed relative to that of gels lacking both surfactants. Additionally, cell discharge performance is improved relative to that of cells lacking both the zinc fines and lowered hydroxide concentration.

  • Patent number: 7094493
    Abstract: A method for absorbing and releasing hydrogen comprises applying repeatedly hydrogen pressurization and depressurization to a hydrogen storage metal alloy of a body-centered cubic structure-type phase exerting a two-stage or inclined plateau characteristic in a hydrogen storage amount vs hydrogen pressure relation in an appropriate fashion to absorb and release hydrogen. At least at one stage during the release of hydrogen, the temperature (T2) of the above-mentioned hydrogen storage metal alloy is made higher than the temperature (T1) of the hydrogen storage metal alloy during the hydrogen absorption process (T2>T1). This enables the release and utilization of occluded hydrogen at a low-pressure plateau region or an inclined plateau lower region.
