Abstract
A high voltage protection system for saddle type vehicle detects the short circuiting of any wire. The high voltage protection system provides three different modules: a high voltage protection circuit, a fault collection circuit, and a fault detection circuit, working together to detect the short circuiting or voltage spike and disconnect the vehicle loads from the power supply to prevent an accident.
Claims9
A high voltage protection system for a saddle type vehicle comprising:
- a switch input signal conditioning module comprising an electromagnetic interference suppressor capacitor to eliminate electromagnetic interference signals from an input power received from a power source and to provide a filtered voltage signal,
- wherein, said electromagnetic interference suppressor capacitor is electrically configured to a leakage current detection circuit and a wetting current circuit;
- a filter circuit enabling said filtered voltage signal to be transferred to a microcontroller;
- a high voltage protection circuit configured to receive said filtered voltage signal;
- wherein, said high voltage protection circuit electrically connects said electromagnetic interference suppressor capacitor and said leakage current detection circuit and said wetting current circuit;
- and
- a fault collection circuit electrically configured to said high voltage protection circuit and a fault detection circuit,
- wherein, said fault collection circuit is configured to receive one or more input signals, from one or more input switches connected to one or more loads in said vehicle, to step down said one or more input signals;
- wherein, said fault detection circuit is configured to receive said stepped down said one or more input signals as an output from said fault collection circuit;
- and
- wherein, said output from said fault collection circuit is compared to a threshold voltage and fed to the microcontroller;
- and said microcontroller disable said vehicle when said output from said fault collection circuit is greater than said threshold voltage.
