MUMBAI, India, Aug. 31 -- Intellectual Property India has published a patent application (202514115553 A) filed by Zhejiang Leapenergy Technology; and Zhejiang Leapmotor Technology on November 22, 2025, for Relay Delay Turn-Off Circuit And Relay Control Method.

Inventors include Liu, Zheng Number; Zhang, Jun; Guo, Yingjie; Xu, Liangdu Number; Wang, Pengfei; and Chen, Yuanjie.

The application for the patent was published on August 28, 2026, under issue no. 35/2026.

Abstract: The application discloses a relay delay turn-off circuit and a relay control method. The relay delay turn-off circuit includes a power control chip outputting a first safety signal, a micro-control chip outputting a second safety signal and a control group signal, a delay module, and a relay driving module. The delay module receives the first safety signal, the second safety signal, and the control group signal, and outputs a first enable signal, a second enable signal, and a safety status signal. When the micro-control chip resets, the first enable signal delays a turn-off action of the relay driving module until after a preset time, which is greater than a reset time. The power control chip and the micro-control chip output the first safety signal and the second safety signal according to their respective safety states to enhance the safety of the circuit through dual safety state determination.
