    Abstract: A control module is arranged in alignment with a battery module in a longitudinal direction. The battery module includes battery cells that are aligned in the longitudinal direction and each have upper and lower end faces opposite to each other in a height direction perpendicular to the longitudinal direction. The control module includes a busbar configured to electrically connect the battery module to an electrical load, a switch configured to switch electrical connection of the busbar with the electrical load between a connected state and a disconnected state, and a controller that controls the switch. In the height direction, the busbar is located closer to the upper end faces of the battery cells than to the lower end faces; the controller is located closer to the lower end faces of the battery cells than to the upper end faces; and the switch is located between the busbar and the controller.

  • Patent number: 10790547
    Abstract: A control module is arranged in alignment with a battery module in a longitudinal direction. The control module includes a busbar, a switch and a current sensor configured to detect electric current flowing through the busbar. The current sensor includes a magneto-electric transducer and a magnetic field suppressor. The magneto-electric transducer is configured to convert a magnetic field, which depends on the electric current flowing through the busbar and passes through the magneto-electric transducer along a plane perpendicular to a height direction, into an electrical signal. The magnetic field suppressor is configured to suppress external magnetic fields from passing through the magneto-electric transducer along the plane perpendicular to the height direction. The switch includes a pair of magnets that are magnetized and opposed to each other in a lateral direction perpendicular to both the longitudinal and height directions. The current sensor is aligned with the magnets in the longitudinal direction.

  • Patent number: 10026923
    Abstract: An electronic component has an organic member between two transparent substrates, in which outer peripheral portions of the two transparent substrates are bonded by a sealing material containing low melting glass. The low melting glass contains vanadium oxide, tellurium oxide, iron oxide and phosphoric acid, and satisfies the following relations (1) and (2) in terms of oxides. The sealing material is formed of a sealing material paste which contains the low melting glass, a resin binder and a solvent, the low melting glass containing vanadium oxide, tellurium oxide, iron oxide and phosphoric acid, and satisfies the following relations (1) and (2) in terms of the oxides. Thereby, thermal damages to an organic element or an organic material contained in the electronic component can be reduced and an electronic component having a glass bonding layer of high reliability can be produced efficiently.

  • Patent number: 9614178
    Abstract: In an electronic component including two substrates at least one of which is transparent, an organic member arranged between these substrates, and a bonding portion located onto respective outer circumferential portions of the two substrates, this bonding portion includes a low-melting glass and filler particles. The low-melting glass includes vanadium oxide. The filler particles include a low thermally-expandable material, and an oxide containing a bivalent transition metal as a constituent element. The oxide is dispersed in the low thermally-expandable material, and the low thermally-expandable material has a thermal expansion coefficient of 5×10?7/° C. or less in a temperature range from 30 to 250° C. This invention makes it possible to heat the filler particles by irradiation with a laser to give the electronic component which is a component having a highly reliable bonding portion.
