Problems solved by technology
[0002] The existing battery inspection instrument in the DC system can only collect the real-time voltage of each battery, because the removed battery may or may not have voltage, and if the battery is removed, the wiring for battery voltage detection has not been removed. At this time, the terminal voltage of the battery can be collected normally. Therefore, the existing battery inspection instrument can only find that the voltage of a single battery is low or high, but it cannot judge whether the battery has been removed.

The invention discloses a storage battery pack battery number and operation state monitoring device, and the device comprises a voltage obtaining unit which is used for obtaining the positive end voltage UN1 and negative end voltage UN2 of each battery in the battery pack, and the end voltage U1-2 of the battery pack; an operation and abnormality judgment unit which is used for obtaining the operation number and the operation state of the batteries in the battery pack; and an output unit which is used for transmitting a result obtained by the operation and abnormality judgment unit to a systemmonitoring host. According to the storage battery pack battery number and operation state monitoring device, the voltage difference value of each voltage detection end can be obtained, the operationnumber and the operation state of the batteries in the battery pack can be judged according to the obtained data, and the result is timely transmitted to the system monitoring host, so that the end voltage can be conveniently and timely adjusted. The invention further discloses a storage battery pack battery number and operation state monitoring method applied to the storage battery pack battery number and operation state monitoring device.
Description
technical field [0001] The invention relates to the technical field of power systems, and more specifically, to a monitoring device for the number and operating state of battery cells. In addition, the present invention also relates to a method for monitoring the number and operating state of the battery pack applied to the above-mentioned device for monitoring the number and operating state of the battery pack. Background technique [0002] The existing battery inspection instrument in the DC system can only collect the real-time voltage of each battery, because the removed battery may or may not have voltage, and if the battery is removed, the wiring for battery voltage detection has not been removed. At this time, the terminal voltage of the battery can be collected normally. Therefore, the existing battery inspection instrument can only find that the voltage of a single battery is low or high, but it cannot judge whether the battery has been removed. [0003] To sum up,...
