  • Patent number: 11971455
    Abstract: A mixed chemistry battery is provided. The mixed chemistry battery includes a reference module having a first chemistry and a battery module having a second chemistry that is different that the first chemistry, the battery module is connected to the reference module in series. The mixed chemistry battery also includes a battery monitoring system configured to monitor an open circuit voltage of the reference module, an open circuit voltage of the battery module, and a current flow through the reference module and the battery module. The battery monitoring system is further configured to calculate a state-of-charge (SOC) and state-of-health (SOH) of the battery module based at least in part on a SOC of the reference module.

  • Publication number: 20240130085
    Abstract: A cooling system includes a housing including a base portion with sides and a bottom surface that define a cavity and a cover portion to enclose the base portion and including cooling members attached thereto. A shield is arranged in the cavity. A vertical member is arranged below the shield to define a first fluid chamber between one side of the vertical member and one side of the base portion and a second fluid chamber between an opposite side of the vertical member and another side of the base portion. The electronic components are arranged in the second fluid chamber. Cooling fluid is arranged in the cavity and has a fluid level below at least a portion of the shield. The housing is mounted at an inclined angle relative to horizontal or the housing is mounted parallel to horizontal and the shield is mounted at the inclined angle.

  • Patent number: 10058959
    Abstract: A method for remanufacturing an ultra-large copper nut includes steps of: step (1) coarsening treatment; step (2) purifying treatment; step (3) detecting a material of the ultra-large copper nut; step (4) sleeving a thermal insulation device; step (5) preheating the ultra-large copper nut; step (6) melting-deposition shaping; step (7) post-processing; and step (8) detecting. The method of the present invention simultaneously utilizes water, electricity, gas, fire and machine and performs melting-deposition on materials by simultaneously supplying water, electricity, gas, fire and machine according to the designed requirements. The method of the present invention solves problems of large thickness abrasion and remediation of fracture components. The method of the present invention is capable of preventing the ultra-large copper nut from deformation and collapse and is a feasible remanufacturing for decreasing the huge economic loss caused by damages of expensive ultra-large of nonferrous metals.
