Portable calibration tool and calibration vehicle

Abstract

The invention discloses a portable calibration tool and a calibration vehicle. The calibration tool comprises: a universal meter; a calibration plate; a control board; an upper cover assembly; and a base assembly, wherein the universal meter is installed and fixed on the base assembly, the calibration plate is fixed on the base assembly, the control panel is connected with the calibration plate and the universal meter and is used for acquiring calibration data, the upper cover assembly covers the base assembly, the base assembly is provided with a network connection port and a socket, and the network component is connected with the control panel. According to the calibration tool, the calibration plates are additionally arranged, the multi-plate and multi-channel calibration mode is achieved in a software control mode, and the calibration efficiency and effect are improved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a portable calibration tool and a calibration vehicle. Background technique [0002] In the testing process of lithium batteries, calibration is the periodic calibration and maintenance of production equipment and testing systems. As the demand for lithium batteries in the market gradually increases, the supporting battery formation and capacity equipment will increase accordingly. Due to the iteration and improvement of battery formation and capacity, the rational use of space, and the reduction of equipment size, many manufacturers will use the space of the site. Composite equipment stacking. Since supporting calibration equipment is essential, usually in order to save costs, only one calibration vehicle is equipped for every dozens of units.

AI Technical Summary

Problems solved by technology

[0003] In the case of multiple floors, a small number of equipment manufacturers still maintain the tradition and equip calibration carts. Due to the small stairs, the calibration carts are generally placed on the bottom floor. When calibrating on the second floor, it is necessary to pull the wires from the calibration cart on the bottom floor to the equipment calibration on the second floor. The wiring harness is too long. The loss seriously affects the accuracy

In the case of multiple layers, most equipment manufacturers are equipped with portable calibration tooling. The portable calibration tooling integrates the calibration board control board into the calibration tooling. At present, employees need to lift the calibration tooling to the vicinity of the equipment during calibration, and the calibration line is connected to the equipment. The network cable is connected to the computer host, and the rubber plug harness is connected to the multimeter, which requires more steps for the staff to operate, and takes a long time to prepare for calibration, which is not easy enough

[0004] Most of the calibration tools are large in size, and the shells are made of thin steel plates. The weight is heavy, and the experience of employees is poor.

Most calibration tools generally use single-board calibration, which is slow in calibration speed and low in accuracy, which affects battery capacity and quality
