The invention provides a charging protection device and method in a defibrillation system. The charging protection device comprises a charging circuit, a charging power supply control unit and a first processor. Dual judgment is conducted through the first processor, wherein firstly, by judging whether the obtained charging voltage is valid or not, line faults are eliminated, and the obtained voltage is the dead voltage; after the obtained charging voltage is judged to be valid, whether the obtained charging voltage meets the preset relation curve of the charging voltage and time or not is judged, charging is determined to be abnormal if the obtained charging voltage is judged not to meet the relation curve of the charging voltage and time, the first processor sends a stop signal to the charging power supply control unit, and the charging power supply control unit controls the charging circuit to stop conducing charging. By means of the dual judgment conducted through the first processor, the real-time and precise control over the charging process of defibrillation is achieved, and when charging circuit faults or abnormal charging happens, the abnormal charging can be found in real time.

The invention discloses a remote vehicle detection and alarming device, which relates to the detection and alarming device and aims to solve the problem that the conventional vehicle failure checking device cannot detect electronic failures of electrical appliances of a vehicle in real time.
