Abstract: A battery system includes a nickel-metal hydride battery and an ECU that controls charging and discharging of the nickel-metal hydride battery. The ECU calculates a discharge electricity amount showing an integrated value of a current discharged from the nickel-metal hydride battery, and further calculates ΔSOC of the nickel-metal hydride battery in a prescribed time period. The ECU calculates a charge reserve capacity of the nickel-metal hydride battery based on a temperature of the nickel-metal hydride battery, the discharge electricity amount, and the ΔSOC.

Abstract: The present disclosure relates to a board for connecting battery cells, which is formed in part from an electrically non-conductive material. The board has on first and second sides at least one electrically and thermally conductive contacting section, and each contacting section is electrically and thermally conductively connected to each other contacting section. A core made of a preferably electrically conductive and thermally conductive material is arranged in the electrically non-conductive material of the board. The contacting section is arranged on the sides of the electrically non-conductive material facing away from the core, and at least one electrically and thermally conductive lead-through element extends through the core and through the electrically non-conductive material arranged on both sides of the core. The lead-through element is electrically insulated from the core. Heat flow can be picked up through the core and dissipated from the board.

Abstract: A battery monitoring apparatus monitors a state of a nickel hydrogen battery. The apparatus includes a board having a high voltage part having a voltage detection section detecting a voltage of the nickel hydrogen battery, and a low voltage part operating at a voltage lower than a voltage of the high voltage part, a housing that accommodates the board, and an attachment member that is attached to an opposed portion of the housing, which is opposed to a board surface of the board to attach the housing to a predetermined position. A passage is formed between the opposed portion and the attachment member. The passage extends from an opening part provided at a circumference part of the housing and along the opposed portion. The passage is provided at a position that overlaps with the high voltage part, when viewed in a normal direction of the board surface.

Abstract: In a battery case sealing method, a lid is fitted to an opening of a battery case, and then a side wall on an inner side of the battery case and a side surface of the lid are brought into contact with each other. The side wall forms the opening. In a state where the side wall on the inner side of the battery case is in contact with the side surface of the lid, a boundary portion between the side wall and the side surface of the lid is welded by irradiating a laser beam in a direction from an outer side of the battery case toward the inner side of the battery case in a thickness direction of the lid.
