5results about How to "Guaranteed redundancy" patented technology

A voltage measuring device may include a bus bar electrically connected to a first terminal and a second terminal of a battery cell, the bus bar extending in a first direction. The shunt resistor may be located on the bus bar and extend in a second direction crossing the first direction. The measurement unit is configured to measure a first voltage value applied to a first sub-region of the shunt resistor, and to measure a second voltage value applied to a second sub-region of the shunt resistor.

This utility model relates to the field of non-ferrous metal casting technology, and in particular to an aluminum alloy casting crystallizer. It solves the problems of existing technologies that lack an externally interconnected and independently adjustable dual-channel water inlet structure, resulting in reliance on two independent water sources for dual-supply systems, low system integration, complex piping, and inconvenient maintenance. An aluminum alloy casting crystallizer includes an aluminum alloy casting crystallizer body and two water inlet pipes located on the top of one side of the aluminum alloy casting crystallizer body. A water supply pipe is located on one side of the aluminum alloy casting crystallizer body, with a top pipe and a bottom pipe at one end. The bottom pipe is connected to the bottom of the top pipe via a connecting pipe. This utility model achieves dual-channel water supply from a single water source through the interconnected top and bottom pipes, improving integration. The on / off state can be controlled by adjusting a screw, allowing for independent opening and closing of the channels, facilitating maintenance and ensuring continuous production.

This invention discloses a crane winch descent energy recovery system and method, belonging to the field of hydraulic system control technology. It solves the problems of traditional gravitational potential energy recovery via accumulators, which result in throttling and heating, large accumulator size, pressure differential, and safety hazards. This recovery system includes a hydraulic pump, electric motor, battery, generator, engine, hydraulic motor, multi-way valve, flow control module, winch motor, and brake. The flow control module consists of a pressure compensation valve and a balance valve connected in series. During descent, the load drives the winch motor to reverse and output high-pressure oil, which drives the hydraulic motor to generate electricity and store it in the battery. During ascent, the battery powers the hydraulic pump, and the electrical energy can also be used for lighting and control systems. This invention replaces the accumulator with a battery, reducing size and extending pressure holding time; the flow control module ensures that the speed does not change with the load weight, but only with the current of the multi-way valve, improving the controllability of lifting speed.

The application discloses a vehicle integrated lithium battery high-voltage power distribution system and a control method. The lithium battery high-voltage power distribution system comprises a high-voltage distribution box, a plurality of battery boxes and a connecting cable for connecting the high-voltage distribution box and the battery boxes and two groups of the battery boxes, which are stacked from top to bottom. The high-voltage distribution box is integrated with a control panel, a filter, a DCDC, a contactor, a fuse, a hard copper bar and a current sensor. The battery box is integrated with a BMS control box. The battery boxes are also connected with liquid cooling pipelines. The system effectively reduces the space occupied by the high-voltage power distribution system on the chassis by using the integrated design of the lithium battery high-voltage power supply and distribution system. By integrating multiple functional modules in one whole, the device layout and installation space are saved, the complexity of the system and the high-voltage cable wiring are reduced, the generalization and interchangeability of the lithium battery and the high-voltage power distribution system are improved, and the redundancy of the vehicle power supply and distribution system is ensured.
