Can a machine leaning approach detect a Li-ion battery's internal short circuit?

Internal short circuit is a very critical issue that is often ascribed to be a cause of many accidents involving Li-ion batteries. A novel method that can detect the Internal short circuit in real time based on an advanced machine leaning approach, is proposed.

How to measure short circuit current in SLCT?

The short circuit current contributed by a single battery in the SLCT is denote by unit Is (clockwise is positive), then the short circuit currents measured by the ammeter A1 and A2 in the different ISCr situations are listed in Table I. In each ISCr situation, the A1 and A2 have corresponding values.

What is a battery internal short circuit (ISCR)?

The battery internal short circuit (ISCr) is one of the major obstacles that impede the improvement of the battery safety. Although most of the ISCr incidents only lead to the loss of battery energy and the decline of the battery performance, some of the ISCr incidents do result in the battery thermal runaway accidents (4).

Can a machine leaning approach detect a short circuit in real time?

A novel method that can detect the Internal short circuit in real time based on an advanced machine leaning approach, is proposed. Based on an equivalent electric circuit model, a set of features encompassing the physics of Li-ion cell with short circuit fault are identified and extracted from each charge-discharge cycle.

How to detect a faulty battery?

The time taken to complete the constant voltage (CV) phase (Tcv) of charging is also a useful feature for ISC detection. Since a portion of the charging current always flows through the short circuit path, the faulty battery takes more time to complete the CV phase, Tcvf > Tcvh. The CC or CP charging time also increases under ISC fault.

Can symmetrical loop circuit topology detect ISCR in battery packs?

Because all of the battery packs are constructed upon the parallel and series circuit topology, the combination of the proposed ISCr detection method for parallel circuits and the former ISCr detection method for series circuits can detect the ISCr in any types of battery packs.
