A method of charging a rechargeable battery pack installed in an electric vehicle is provided in which the charging system includes a switching circuit that is operable in at least a first mode and a second mode. In the first mode the switching circuit couples the power supply and an external power source to both a heater and the charging circuit, the heater providing a voltage divider circuit within the charging circuit. In the second mode the switching circuit couples the power supply and the external power source only to the charging circuit, bypassing the heater.

Method of operating a recharging system utilizing a voltage dividing heater

An apparatus comprising a rechargeable battery pack installed in an electric vehicle, a power supply coupled to the rechargeable battery pack, the power supply operable to provide a charge voltage to perform charging operations on the rechargeable battery pack, a heater to heat a fluid to be circulated through the rechargeable battery pack, the fluid thermally coupled to a plurality of battery cells within the rechargeable battery pack, a switching circuit, the switching circuit coupled to the heater and to the power supply, the switching circuit operable in a first mode to couple the source of electrical power to the heater without coupling the source of electrical power to the rechargeable battery pack, the switching circuit operable in a second mode to couple a source of electrical power external to the electric vehicle to the power supply to form a recharging circuit in order to perform charging operations on the rechargeable battery pack.

Voltage dividing vehicle heater system and method

An apparatus including a rechargeable battery pack installed in an electric vehicle, the rechargeable battery pack coupled to a power supply, the power supply operable to provide a charge voltage to perform charging operations on the battery pack, a heating element to heat a fluid to be circulated through the rechargeable battery pack, a comparator circuit to compare a battery voltage of the rechargeable battery pack to a line source voltage, the comparator circuit operable to compare the battery voltage to the line source voltage and to provide an output signal when the battery voltage is less than a line voltage offset value, and a control circuit coupled to receive the output signal of the comparator, and to couple the line source voltage to the power supply, an to bypass the heating element if the comparator is not providing the output signal.

Systems, methods, and apparatus for battery charging

A method of mitigating propagation of a thermal event in an energy storage system having a plurality of cells is disclosed. The method includes the steps of identifying the heat sources within the energy storage system and plurality of cells. The method then controls a temperature of the energy storage system and plurality of cells and also detects predetermined conditions within the energy storage system. The method then performs a predetermined action based on when one of the predetermined conditions is detected. A plurality of sensors and switches along with associated hardware or software will be used to control the temperature of the energy storage system upon detection of predetermined conditions involving overheating, over current, over voltage of the like.

Mitigation of propagation of thermal runaway in a multi-cell battery pack

A hermetically sealed carrier for integrated circuits has an IC placed on a carrier substrate, and an electrical lead apparatus, comprised of a highly heat resistant substrate with a metallized interconnect pattern deposited thereon, connected to the IC and brought out across and over the edges of the carrier substrate to facilitate electrical connection to a circuit board. A lid is provided which is placed over the IC. A low-melting temperature adhesive means is then placed on the lid-to-carrier interface and is exposed to heat hermetically sealing the IC. A hermetically sealed carrier including a single silicon die which includes both an active region where an integrated circuit may be fabricated and an inactive region is also provided. Electrical leads are electrically interconnected to the IC of the active region and extend to the periphery of the inactive region of the silicon die. A lid and adhesive means is provided for hermetically sealing the IC of the active region.
