A short piece of thick wire will look like a short circuit (a few milliohms). A very long, thin wire will look like a resistance which you can calculate by multiplying (ohms per meter of that gauge wire) x (meters of wire).

6 FAQs about [How to calculate the current of battery current limiting]

What are battery limit calculations?

How are current limits calculated?

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.

What is the current limit of a battery limiter?

The current is limited to approximately 1A (≈1.25V / R2) in this battery limiter. Note that the minimum voltage drop across the limiter is about 2.5V. In your design, the point where the current starts to drop is the constant-voltage value from your regulator.

A simple current limiter can be built using an LM317 IC regulator (LTspice simulation below). Install it between the input supply voltage and your constant-voltage circuit to limit the current. The current is limited to approximately 1A (≈1.25V / R2) in this setup. Rload (horizontal axis resistance value) simulates the increase in voltage as the battery charges.

What is a current limit estimate (CLE)?

To address this challenge, we define the current limit estimate (CLE), which is the maximum current that can be extracted and sustained from the LIB system for a given pulse duration, at a given point of discharge SOC, at a particular cell temperature, that will take the LIB system to a pre-defined voltage cut-off at the end of the pulse.

What is current limit estimation?

These current limits are time dependent and constantly changing. Therefore, current limit estimation or State of Power (SoP) estimation is a continually evolving map. Typically the time window will be from 1 second to 30 seconds for an electric vehicle.
