The maximum current calculation for CLE is based on calculating the SOC cutoff (which the system will reach to, within the given CLE time duration, Δt) using an initial guess of the CLE (set to the present value of current), then updating this current value using equation (16), until the convergence criterion is met as shown in Table 2.
1) The battery has a maximum power it can provide. For example, if this power is P = 100 W, then since P = RI^2 the current will be I = (P/R)^0.5 = 31.6 amps and the voltage V = RI = 3.16 V. 2) The battery has a maximum current it can provide. For example, if this current is I = 5 A, then V = RI = 0.5 V.
During the 1c current limit charge phase, the battery reaches 4.2V with only about 65% of charge capacity delivered, due to the voltage drop across the ESR. The charger must then reduce the charging current to prevent exceeding the 4.2V limit, which results in the decreasing current as shown in Figure 5.
Calculate the internal resistance of the battery. This can either be calculated from the equation ε = V + Ir or it can be read from the graph, using the maximum power theorem as described above. We have already calculated the values of V and I so using the equation, and making r the subject:
The current can be found from Ohm's Law, V = IR. The V is the battery voltage, so if R can be determined then the current can be calculated. The first step, then, is to find the resistance of the wire: L is the length, 1.60 m. The resistivity can be found from the table on page 535 in the textbook. The area is the cross-sectional area of the wire.
The current limits are estimated using this validated cell model and the CLE profiles are generated at the different operating conditions. For these estimates, the pulse duration is fixed at Δt = 1s and the cut-off voltage at Vcut-off = 3 V.
About 65% of the total charge is delivered to the battery during the current limit phase of charging. Assuming a 1c charging current, it follows that this portion of the charge cycle will take a maximum time of about 40 minutes. The constant voltage portion of the charge cycle begins when the battery voltage sensed by the charger reaches 4.20V.

A switch is used to control the current in the circuit, and power is supplied by a 6 V battery. When the switch is closed, the inductor will briefly oppose the change in current from zero to some magnitude but will drop only a small amount of voltage.

This voltage opposes the battery, growing from zero to the maximum emf when fully charged. The current thus decreases from its initial value of (I_9 = frac{emf}{R}) to zero as the voltage on the capacitor reaches the same value as the emf. When there is no current, there is no (IR) drop, and so the voltage on the capacitor must then equal ...
