A method for manufacturing a battery, which has a battery housing and at least one cell module, the cell module being introduced into the battery housing to form an intermediate space between a wall of the battery housing and the cell module, and a heat conducting medium then being introduced by an introduction device into the intermediate space. One operating mode is selected from a first operating mode of the introduction device and a second operating mode of the introduction device and is used for introducing the heat conducting medium, with the introduction of the heat conducting medium in the first operating mode occurring with an introduction volume flow set to a preset volume flow and in the second operating mode occurring with an introduction pressure set to a preset pressure.

An all-solid-state battery control system includes an all-solid-state battery, a housing, a fluid, a pressurizer, and a processor. The all-solid-state battery includes a solid electrolyte. The housing has a space containing the all-solid-state battery. The fluid is configured to fill the space of the housing. The pressurizer is configured to apply pressure to the all-solid-state battery via the fluid. The processor is configured to control a magnitude of the pressure to be applied to the all-solid-state battery by the pressurizer, on the basis of a temperature of the all-solid-state battery and a state of charge of the all-solid-state battery.

A film-packaged cell has a flat rectangular shape where power-generating element is housed in packaging body together with an electrolytic solution, the film-packaged cell being sealed along four edges of the packaging body in a state where terminals are led out through one edge thereof. In an electrolyte injection step, the electrolytic solution is injected into bag-shaped body where three edges excluding the upper edge of the packaging body are sealed in an orientation where the terminals are protruding laterally, the electrolytic solution being injected from the side of the opening upper edge. In a partial sealing step performed before the electrolyte injection step, only one section of opening upper edge of the bag-shaped body near edge through which terminals are led out is partially sealed, thereby preventing the electrolytic solution from leaking out during electrolyte injection.

A system for watering an electrolyte or lead acid battery in which the cumulative amount of water added during each filling event is determined by detecting the amount of water passing from a supply hose to the battery. A fluid dispensing member, such as a direct fill link or nozzle, can be attached to and detached from a single point watering subsystem. A flow detector, such as a flow meter, in fluid communication with the fluid dispensing member can wirelessly output the cumulative water added to specific batteries to an interactive computer application, which can include a wireless component such as a smartphone or tablet communicating with a remotely located interactive database.
