  • Publication number: 20250055163
    Abstract: A system includes a first battery, a second battery, and a battery connector coupling the first battery to the second battery. The battery connector includes a first portion and a second portion. The second portion is narrower than the first portion. The second portion is configured to decouple the first battery from the second battery when a current above a threshold current passes through the second portion.

  • Patent number: 11811262
    Abstract: According to certain aspects of the disclosure, an uninterruptible power supply is provided comprising an input, a backup power supply, an output configured to provide output power from the input and/or the backup power supply, a sensor, a relay, and a controller coupled to the sensor and the relay and being configured to determine, based on stored relay specifications, a manufacturer total estimated relay lifetime, receive operational information indicative of operational parameters of operation of the relay from the sensor, the operational information including a current conducted by the relay, determine, based on the operational information, an effective number of relay cycles consumed by the operation of the relay, determine a modified number of remaining relay cycles based on a difference between the manufacturer total estimated lifetime and the effective number of relay cycles consumed, and output remaining relay lifetime information indicative of the modified number of remaining relay cycles.

  • Publication number: 20230198210
    Abstract: A cable connector includes a slide coupled to a spring to bias the slide from a retracted position to an extended position and at least one latch coupled to the slide. The slide, when in the extended position, is configured to rotate the at least one latch to secure the at least one latch, and when in the retracted position, is configured to rotate the at least one latch in an opposite direction to release the at least one latch. The slide is configured to engage a contact switch when securing the at least one latch.
