Abstract: A connecting structure is applied for connecting an electric wire and a terminal. For coating a connecting portion of a conductor of the electric wire and the terminal, which form a wire harness, with a coating resin, a portion of an insulator, which is to be inserted into a terminal insertion hole of a connector housing, is subjected to a diameter reduction process such that an outer diameter of the coating resin coated on the insulator is smaller than the terminal insertion hole.

Abstract: A charge acceptance limit determination apparatus includes a voltage measuring unit that measures a voltage of a secondary battery, a current measuring unit that measures an electric current flowing through the secondary battery, and a determining unit that determines whether or not the secondary battery has reached a charge acceptance limit in accordance with a position on a current-voltage plane of a voltage value and a current value that are measured by the voltage measuring unit and the current measuring unit.

Abstract: A secondary battery state detecting apparatus for detecting a state of a secondary battery installed in a vehicle is provided, which includes a current detecting unit that detects an electric current flowing to the secondary battery, a voltage detecting unit that detects a voltage of the secondary battery, and a determining unit that determines, in a case where an external device is directly connected to terminals of the secondary battery and the secondary battery is charged or discharged without passing through the current detecting unit, whether or not an irregular charging-discharging has occurred, in accordance with a change in a current value and a voltage value detected by the current detecting unit and the voltage detecting unit.

Abstract: A full charge sensing apparatus for sensing a fully charged state of a secondary battery based on an equivalent circuit model of the secondary battery includes a measuring unit that measures a voltage and a current during charging of the secondary battery, a learning unit that performs a learning process on a plurality of parameters in the equivalent circuit model using a result of measurement of the measuring unit, and a determining unit that determines that the secondary battery is in a fully charged state in a case where, among the parameters on which the learning process has been performed by the learning unit, a parameter corresponding to a reaction resistance of the secondary battery is greater than a predetermined threshold.

Abstract: The board has a transformer, choke coil and, for example, is used for a DC-DC converter such as for an automobile. At the board, a circuit conductor therein is exposed to outside at an electronic component mounting part, a printed board mounting part and a conductor part, and other portions are covered with resin to form an injection molded board, which installs an electronic component, etc. The printed board mounting part is a section that is provided for installing a printed board. A conductor part of the printed board and the conductor part of the printed board mounting part are joined via an electronic component by soldering, etc.

Abstract: A substrate has a coil that is a choke coil part and, for example, is used for controlling a motor. At the substrate, an electronic component mounting part is formed such that a circuit conductor therein is to be exposed to outside. A portion other than an externally connected portion such as the electronic mounting part is covered with substrate-forming resin to form an injection molded circuit board. The coil arranged at the substrate (the injection molded circuit board) is provided for smoothing current inputted from outside. A core part is formed at the coil by core-forming resin such that the coil part covers at least a center core part of the coil.
