Needle-bar formula automobile battery grading cabinet

Abstract

The invention discloses a needle-bar formula automobile battery grading cabinet. The needle-bar formula automobile battery grading cabinet comprises a main body, a clamping device used for clamping batteries, and a control device arranged on the main body; the control device comprises a driving member, a control part used for controlling the driving member, and a control system; the control part comprises a hand-operated elbow clamp and a connecting piece; one end of the connecting piece is fixedly connected with the driving member, and the other end is connected with the hand-operated elbow clamp through hinge joint; one end of the hand-operated elbow clamp is connected with a cabinet body through hinge joint, and the other end of the hand-operated elbow clamp is capable of rotating around a shaft at the joint connection part of the first end of the hand-operated elbow clamp and the cabinet body; the control system comprises a charging and discharging system based on PWM control, an inverter used for increasing and reducing voltage, and an AC / DC converter used for converting alternating current into direct current; one end of the inverter is connected with the AC / DC converter, andthe other end of the inverter is connected with a load; the charging and discharging system is connected with the inverter; an elastic element is adopted by the battery clamping device for connectionof a hinge device with a fixed framework; and deformation of the elastic element can be induced.

Description

technical field [0001] The invention relates to the field of storage cabinets, in particular to a bed of needles type automotive battery storage cabinet. Background technique [0002] Lithium-ion power batteries have the advantages of high energy density, no memory effect, many cycles, and long service life, providing technical support for the popularization of electric vehicles, a zero-emission, pollution-free vehicle. However, the preparation technology of lithium-ion power batteries is relatively complicated, and the requirements for production conditions are relatively strict. Especially during the formation of lithium-ion power batteries, there are a small amount of air bubbles inside the battery. If left untreated, these air bubbles will always exist in the battery. After a long time of use, the part of the battery with air bubbles will continue to expand, resulting in an increase in the separation range of the plates and a decrease in battery capacity. When the bat...

AI Technical Summary

Problems solved by technology

When the battery is overcharged or overdischarged, the phenomenon of flatulence in the battery will be further aggravated, which will seriously affect the cycle life and discharge performance of the battery, and may cause liquid leakage and cause the battery to be scrapped
