[0028] Such as Figure 1-2 As shown, in the first example of the present invention, a fault detection system for a lithium battery is provided, and the system includes:
[0029] The test data collection module 100 is configured to take at least three first types of test lithium batteries, and respectively collect first test data G of the test lithium batteries in real time. (n,m) ; The first test data includes open circuit voltage V b(n,m) , Capacitor voltage V s(n,m) , Battery terminal voltage V (n,m) And working current I (n,m) The n is the serial number of the first type, and the n is a positive integer; the m is the serial number of the first test data, and the m is a positive integer;
[0030] The test data processing module 200 is configured to perform according to the first test data G (n,m) , Get the first output data column Y n (m) and the first input matrix Φ (n,m) ;
[0031] The first output data column Y n (m) Meet: Y n (m)=(V b(n,1) ,V b(n,2) ,...V b(n,m) ) T ;
