So I can calculate the short circuit current with the internal resistance as: 3.5V 0.00045Ohm = 7777.78A 3.5 V 0.00045 O h m = 7777.78 A. So the internal power generated is: 7777.78A2 ∗ 0.00045Ohm = 27222.23W 7777.78 A 2 ∗ 0.00045 O h m = 27222.23 W. Energy it takes to heat up a cell by 35 kelvin. Cell weight: $3.3kg$.
A simple ECM is used to better analyze ISC characteristics. The green cell of Fig. 1 (a) shows a Rint model of a normal cell, in which U and U OC separately are the terminal voltage and open circuit voltage, R i refers to the internal resistance and I is the current. Once early ISC occurs in the battery, a tiny channel is formed between the
In this type, as illustrated in Fig. 23.12, when the battery is fully charged, the PV panel is short-circuited using an electronic switch (S 1). Unlike series controllers, this method works more efficiently even when the battery is completely discharged as the short-circuit switch need not be activated until the battery is fully discharged [1].

The most typical type of fault is a short circuit. On the power grid, short circuits can occur, for example, when two wires touch, or when a tree touches a wire. This causes the generators to produce a big surge of electrical current. This is called fault current, and it can lead to fires and damage equipment if not corrected.
