Abstract: A battery module is provided including a battery unit that includes a battery top cover; a temperature measurement unit, including a temperature collection element to collect temperature of the battery top cover; a harness plate, arranged on the battery top cover and including a harness plate body and a limiting structure arranged on the harness plate body, wherein the limiting structure is matched with the temperature measurement unit; a circuit board, arranged on the harness plate and including a circuit board body and an extending strip arranged on the circuit board body, wherein the temperature collection element is connected with the extending strip; and an electrical connecting sheet arranged on the harness plate to connect different battery units, wherein the temperature measurement unit is arranged between the electrical connecting sheet and the battery top cover, and the electrical connecting sheet exerts pressure onto the temperature measurement unit.

Abstract: Disclosed is a method for aging an alcohol product by using intelligent ultrasonic technology. A sealed stainless-steel aging cylinder is arranged on a bracket in advance, and the bracket is arranged above a stainless-steel tank provided with an ultrasonic generator at the bottom, so that indirect ultrasonic aging is performed on a new alcohol product in the stainless-steel aging cylinder. Firstly, a water-injecting sub-process is initiated; an alcohol product-feeding sub-process is initiated and a specific aging sub-process is initiated; a temperature control sub-process is synchronously performed during the aging process; and an alcohol product-discharging sub-process is initiated. After the alcohol product-discharging sub-process, determining whether the alcohol product is required to replace can be added. If yes, a gas-washing sub-process is initiated, and if not, the alcohol product-feeding sub-process is directly performed to continue aging.
