6 FAQs about [Battery input current limiting]
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.
What happens when you limit the current?
When you limit the current, the voltage will consequentially be less than it would have been without the limiting. A simple current limiter can be made with a LM317 IC regulator (LTspice simulation below). It can be installed between the input supply voltage and your constant-voltage circuit.
What is AC input current?
;) Hello, The Ac input current is measuring the current on the AC input and controls this with PowerControl (charging the charge current to avoid AC input overload) or PowerAssist (adding energy from the battery to the AC power). Its starts regulating at app 80% of the setpoint at the normal setting.
How can I build a simple current limiter?
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.
Can you control voltage and current simultaneously?
You cannot control both voltage and current simultaneously in a battery charger. If the voltage is held constant, then the current will be determined by the load (battery). Conversely, if you limit the current, the voltage will be less than it would have been without the limiting.
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.
