6 FAQs about [How to measure reverse current battery]
What is reverse current in a power supply?
Reverse current is where the load attempts to force current back into the power supply source. Such instances can occur when the power supply source is suddenly reduced or completely lost, and the load supply bypass capacitors or batteries attempt to force current back into the power source when first connected.
How can a reverse battery be protected?
A solution with relay is not taken into account. The easiest way for reverse battery protection would be a series diode in the positive supply line to the ECU accordingly the load. By applying the battery in the wrong polarity the pn junction of the diode blocks the battery voltage and the electronics are protected.
What is battery reversal protection?
A variety of circuits can provide this assurance. The simplest form of battery-reversal protection is a diode in series with the positive supply line (Figure 1a). The diode allows current from a correctly installed battery to flow to the load and blocks current flow to a backward-installed battery.
Why is reverse current protection important?
Reverse current protection is important in distributed, redundant, or hot-swap power supply applications where the loads could potentially force current back into the main bus voltage. Reverse current is where the load attempts to force current back into the power supply source.
Does simple reverse voltage protection protect against reverse current flow?
Simple reverse voltage protection can be added using several schemes involving diodes & MOSFETS, but they do not protect against reverse current flow. Reverse current protection is important in distributed, redundant, or hot-swap power supply applications where the loads could potentially force current back into the main bus voltage.
Do you need reverse current protection for a battery-operated device?
In battery-operated devices that have removable batteries, you usually need to prevent the batteries being connected the wrong way to prevent damage to the electronics, accidental short-circuiting, or other inappropriate operation. If that is not possible by physical means, you need to include some electronic reverse current protection.
