Control system and control method for temperature of power battery baking oven

Abstract

The invention relates to a control system and a control method for the temperature of a power battery baking oven. The control system comprises a temperature acquisition and inspection module, a temperature control module, a PLC (Programmable Logic Controller), an upper computer, a solid-state relay and a baking oven, wherein each panel in the baking oven is provided with a heating plate, the eachheating plate is connected with a temperature sensor, the temperature acquisition and inspection module acquires the temperature of each heating plate in the baking oven through the temperature sensors, the temperature control module is connected with a coil of the solid-state relay and interactively connected with the temperature acquisition and inspection module, and the PLC is in interactive connection with the temperature control module and the upper computer. According to the control system and control method for the temperature of the power battery baking oven, modular independent control can be performed on the baking temperature, the design is more reasonable, and the calibration is carried out more simply and more easily on the one hand; and on the other hand, the temperature acquisition and inspection module is additionally arranged, thereby achieving real-time temperature monitoring in the whole process, and improving the safety and the reliability.

Description

technical field [0001] The invention relates to the technical field of power energy battery production, in particular to a control system and method for controlling the temperature of a power battery oven. Background technique [0002] Baking to remove moisture is a very critical step in the production process of existing power batteries. Traditional battery baking control has technical bottlenecks in temperature uniformity, temperature control deviation, and temperature control accuracy. It is designed as a large-area overall heating Plate; the heating plate is connected to more temperature sensors to measure different temperature points in a large area as a whole. During the temperature control process of the heating plate, the temperature controller is difficult to separate to control different positions of the heating plate separately, resulting in different positions inside the oven. The temperature uniformity effect cannot reach a rational state, and the baking will on...

[0002] Baking to remove moisture is a very critical step in the production process of existing power batteries. Traditional battery baking control has technical bottlenecks in temperature uniformity, temperature control deviation, and temperature control accuracy. It is designed as a large-area overall heating plate; the heating plate is connected to more temperature sensors to measure different temperature points in a large area as a whole. During the temperature control process of the heating plate, the temperature controller is difficult to separate to control different positions of the heating plate separately, resulting in different positions inside the oven. The effect of temperature uniformity cannot reach a rational state, and the baking will only collect and display the baking temperature and baking time. There is no design in the program to calculate the temperature data deviation of different positions on the heating plate, and real-time adjustment can be made to control the temperature uniformity and consistent baking sex is imprecise
