  • Publication number: 20230170539
    Abstract: A controller makes it possible to more securely execute, when a thermal runaway occurs in a battery pack, communications for a fail-safe action with an external device. A controller is configured to execute, when a thermal runaway occurs in a battery pack, communications for a fail-safe action with an external device. A first battery module is arranged on a side farther than the controller in a first direction. A second battery module is arranged on a side farther than the controller in a second direction that is a direction opposite to the first direction. A first wire extends from the controller in the first direction and passes immediately above the first battery module. A second wire extends from the controller in the second direction and passes immediately above the second battery module, and has a function identical to a function of the first wire in the communications.

  • Patent number: 7835156
    Abstract: In a power drive unit having power modules (three-phase inverter circuits) connected to a control circuit board, bus bars extending from the power modules and a current sensor each installed near the bus bars and including a sensing element that detects currents outputted from the bus bars, there are provided a sensor board on which the sensing element is mounted, and lead pins each connecting the sensor board to the control circuit board and having a bowed shape whose one end is connected to the sensor board and other end once extends away from the circuit board and then turns back toward the circuit board. With this, the circuit board and current sensors can be connected through the lead pins without increasing the distance therebetween and stress produced in the lead pins can be alleviated, thereby enabling the unit to be minimized in size and utilized in a harsh service environment.

  • Patent number: 4588551
    Abstract: An article comprising a first portion which is formed porously by sintering of an alloy or cermet material and a second portion which is formed of a metal and intimately bonds to the first portion. For example, the article is a rocker arm for an automotive internal combustion engine, in which first portion is the wear-resistant tip portion and the second portion the body portion. The second portion is formed by molten metal forging, with the sintered first portion set in the mould as an insert, such that the molten metal under pressure is forced to infiltrate into the pores of the sintered first portion at least in a region contiguous to the interface between the first and second portions. This article features very high strength of the bond at the interface between the first and second portions.
