  • Publication number: 20250023125
    Abstract: Intelligent lead-acid battery system capable of monitoring a parameter (e.g., voltage, temperature) of one or more battery cells of a lead-acid battery. In one implementation, the battery system includes a housing having a cells compartment, a battery monitoring system (BMS) compartment, and a wall disposed between the cells compartment and the BMS compartment. A first post and a second post are associated with a battery cell. The first post and the second post protrude through the wall between the cells compartment to the BMS compartment. A voltage sensor electrically couples to the first post and the second post to monitor the voltage of the battery cell. A temperature sensor can couple to the first or second or both posts. The intelligent AGM battery system can predict the battery module's state of health, state of charge, module status, power capability, life expectancy, etc.

  • Publication number: 20240258626
    Abstract: Female-style terminals for an electrical power storage device is described herein. The terminals include one or more features that provide a more secure connection between a vehicle connector and the terminal compared to traditional clamp-style connectors. The terminals can include an annular ring or groove. The terminals can additionally or alternatively include a threaded portion and one or more protrusions. The electrical power storage device includes a cover, a portion of the cover adjacent to the terminal includes a keyed section to secure the connector. The disclosed terminals reduce or eliminate movement of the connector relative to the terminal, thereby reducing wear and increasing the performance of the connection.

  • Publication number: 20240021953
    Abstract: A vent adaptor for placement inside a vent aperture that is itself placed within a battery housing. The vent adaptor has a cylindrical portion and a seal to create a gas-tight seal around the vent aperture. Along the upper portion of the vent adaptor are teeth which function to lock the vent adaptor in various configurations depending on the number and orientation of the various teeth and their interaction with various indentations in the vent aperture. The cylindrical portion may also have ribs with various geometries spaced at particular intervals to prevent the egress of the vent adaptor from the vent aperture. The vent adaptor may have internal diameter of at least 5 millimeters to accommodate an appropriately sized vent tube. A batten 7 with a housing that contains a vent aperture and a vent adaptor located inside the vent aperture.
