Greenway has obtained utility model patent authorization: "Isolation power supply drive circuit and power battery"

Article Source：Qichacha | Author：Securities Star News | Issuing Time：2024.04.02
Securities Star News: According to data from Qichacha, Greenway (688345) has recently obtained a utility model patent authorization, titled "Isolation Power Drive Circuit and Power Battery", with patent application number CN202321781248.7 and authorization date of March 15, 2024.



Patent abstract

This application provides an isolated power supply driving circuit and a power battery. The isolation power drive circuit mentioned above includes an isolator and an input enable circuit; The input enabling circuit includes a first electronic switch tube, a second electronic switch tube, a first resistor, and a second resistor. The input end of the isolator is connected to the first end of the first electronic switch tube, the input end of the isolator is also connected to the first end of the first resistor, the second end of the first resistor is connected to the control end of the first electronic switch tube, the second end of the first resistor is also connected to the first end of the second resistor, and the second end of the second resistor is connected to the first end of the second electronic switch tube. When the discharge signal is output, the first and second electronic switching tubes conduct, allowing the input enable voltage output from the second end of the first electronic switching tube to be used for driving, thereby isolating and distinguishing the input enable voltage from the driving voltage, effectively improving the isolation degree between the input enable voltage and the driving voltage.



Attached figures of the abstract

Since the beginning of this year, Greenway has obtained 37 new patent authorizations, a decrease of 35.09% compared to the same period last year. Based on the company's mid year financial data for 2023, the company invested 63.4102 million yuan in research and development in the first half of 2023, a year-on-year increase of 15.75%.
