Current Limit and Short Circuit Protection in Power Restricted Load

To overcome the issue of these high current events, there are load switches that offer two distict protection methods; namely short circuit protection (SCP) and current limitng (CL). Short circuit protection is triggered when the device is enabled and the voltage difference between the input and output increases.

What Affects the Power Output of a 12V 100Ah LiFePO4 Battery

1. Battery Voltage (State of Charge - SoC) LiFePO4 batteries maintain a relatively flat voltage curve throughout discharge, typically ranging between 12.8V to 13.6V when charged and around 12V when nearly empty.. The power output decreases slightly as the battery discharges because of this drop in voltage, but the flat discharge profile ensures consistent

When the battery voltage is near to the required minimum input voltage of the regulator, it can affect the regulated output. It is advised to use a fully charged battery for evaluation and to recharge the battery as soon as the low battery output indicator is turned ON. External Power Supply Header:

Understanding Battery Basics: Chemistry, Voltage, Capacity

Understanding battery basics, including chemistry, voltage, and capacity, is essential for anyone using electronic devices or electric vehicles. Battery capacity indicates how much energy a battery can store, while voltage determines the power output. Together, these factors influence the performance and longevity of batteries in various

For your 9.6V battery you get current less than 1A (1C rate) if the resistance is more than 9.6 ohms. If resistance is less than 3 ohms you are probably discharging your battery at too high a rate. Ground the output with a current sense resistor and use a solenoid or relay as the inductor and it is similar to the original circuit above.

6 FAQs about [What to do if the battery output power is limited]

Should you use a load switch if you run off battery power?

When the power budget is restricted as in the case of battery applications, current limiting is preferred as the voltage on the input rail is held stable. Portable electrical systems running off battery power benefit greatly from using load switches as these applications are sensitive to quiescent current and thermal efficiency.

What happens if you run a battery over a maximum discharge rate?

A high discharge event caused during short a short circuit could cause the voltage to dip to unsustaiable levels. Running a battery over the specified maximum discharge rate could damage the battery and should be avoided in most applications. Figure 4.

Why do Lib batteries need to be charged?

The discharge performance of LIBs has different requirements than charging, as the battery needs to satisfy required discharge power, for example, to support speeding or climbing in EVs and playing games or using power hungry apps on mobile electronics. Often times there is need for short bursts of large power or pulse power to support the load.

What happens if a power supply draws too much?

The exact behavior beyond that basic statement depends on too many things. But for sure, if the load draws more than the supply can put out, the voltage will go down. That much is safe to say. Varies. Shuts down, foldback, hick-up or constant current limit. Do you have a datasheet for it or have you asked the manufacturer?

What is power limit estimation?

The CLE concept PLE or power limit estimation is widely used to characterize battery state of power, whose main aim is to calculate the limits of a battery operation through the maximum power/current extractable at a particular time point in charge/discharge [15, 29].

How accurate is a power limit estimation method?

We validated our method against power limit estimation experiments on a commercial mobile battery and achieved accuracies >98%. It should be noted that the high accuracy is achieved even at low temperature conditions (0 °C) and at extremities of cell discharge, where the non-linear behaviour is pronounced.
