The invention discloses a fault detection device applied to a storage battery of a charging and discharging board. A temperature sensor is mounted in the storage battery box and is in communication connection with a PLC, a charger is in communication connection with two ends of a storage battery system, the charger and the storage battery system form a closed loop, a current monitoring module is connected in the closed loop, a first voltage monitoring module measures a voltage between first storage battery packs, a second voltage monitoring module measures a voltage between second storage battery packs, the second voltage monitoring module is connected with a communication conversion module after the first voltage monitoring module is in communication connection with the second voltage monitoring module, and the communication conversion module and the charger are both in communication connection with the PLC. The fault detection device is advantaged in that the voltage monitoring modules, a current monitoring module, a converter module and other modules are additionally arranged in the charging and discharging board, important performance parameters such as internal resistance, thevoltage and the current of the storage battery are detected in real time, faults of the storage battery can be rapidly diagnosed, and thereby reliability of emergency power supply is improved.
Description
technical field [0001] The invention relates to the technical field of ship power equipment, in particular to a fault detection device applied to a charging and discharging battery. Background technique [0002] With the rapid development of the shipbuilding industry, battery DC power supply technology is used in many important emergency power supply equipment. However, due to the potential problems of some batteries in the battery pack, there have been many accidents. The detection is not real-time, and the failure of the storage battery cannot be guaranteed to be diagnosed, and the reliability of the emergency power supply is low. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies of the prior art, the present invention provides a fault detection device applied to the charging and discharging battery. The device can solve the problem that the fault of the battery in the emergency power supply equipment cannot be found in ti...
