Latest Patents

Xiang Ao holds a patent for a relay diagnostic circuit. This invention discloses a relay diagnostic circuit designed for multiple relays connected in series between an electric vehicle power supply and a load or charging end. The circuit includes several voltage divider branches connected to a common reference ground, an isolation unit, and a judgment unit. Each voltage divider branch is configured to measure the voltage at one end of each relay and output the divided voltage. The isolation unit isolates and converts the divider voltages, sending them to the judgment unit. The judgment unit then compares the divided voltages at both ends of each relay with the corresponding driving state of the relay to determine the diagnosis result for each relay.
