    Abstract: A device for indicating over-temperature of one or more battery cells includes a thermal sensor proximate to a battery cell, a controller in electrical communication with the thermal sensor, and a switch and resistor connected in series across the battery cell, which are controlled by the controller. The device detects whether a given battery cell or group of cells reaches a temperature over a threshold temperature. When the threshold is exceeded, the device causes the battery cell to exhibit a duty cycle of voltage change across the terminals of the battery cell. A battery management system (BMS) monitors the voltage of the battery cell and detects the duty cycle as an indication that a temperature fault in the form of a temperature over a threshold temperature has occurred.

    Abstract: A battery system employs a plurality of PTC devices and an additional temperature sensor to provide safety and optimization features in a multi-cell battery system. The system provides both temperature fault detection and information that may be used for battery system performance optimization. A single negative temperature coefficient (NTC) thermistor and multiple PTC thermal protection devices are integrated into a battery block, and can be implemented as a single sensor package that is in thermal contact with each of the battery cells in the battery block.

    Abstract: A heat-sensitive material comprising a heat shrinkable material (e.g., a heat shrinkable resin) having dispersed therein electrically conductive particles, which shrinks on heating to allow an electric current to flow. A heat-sensitive element comprising the heat-sensitive material and a pair of electrode terminals is useful as an over-charge protective element of lithium ion secondary batteries.

    Abstract: A battery module includes: a plurality of aligned battery cells having differently-oriented surfaces; a cell supervision circuit (CSC) configured to receive signals corresponding to the voltage and/or temperature of at least one of the battery cells; and a flexible interconnector comprising a strip-shaped flexible printed circuit (FPC). The FPC includes a first insulating main surface, a second insulating main surface opposite the first insulating main surface, and a plurality of thermally and/or electrically conducting lines between the first insulating main surface and the second insulating main surface. Each of the conducting lines has a contact portion exposed by a contact aperture in the first insulating main surface and/or in the second insulating main surface and a connecting portion for connection to the CSC, and the flexible interconnector wraps around the battery cells such that the contact portions contact the differently-oriented surfaces of the battery cells.
