6 FAQs about [Backup battery load current specification]

What's new in a BBU battery backup unit?

The most significant change in the specification is that the design is now migrating from a 12 V to a 48 V architecture. This is Part 2 of a five-part series highlighting Analog Devices’ reference design for the battery backup unit (BBU).

How can a battery-operated system be extended?

Extending the life of a battery-operated system enhances the experience people have with the product and can potentially cut replacement costs. The battery life of products can be extended by considering current consumption, battery stress, and battery deterioration.

Why does my Vout need a backup power source?

Main power needs to source the VOUT while it is above the backup power. However, main power can fall below backup power due to weather conditions. If the main power is low, then the system needs to switchover to a backup power source without interrupting normal operation.

What is the capacity of a battery or accumulator?

The capacity of a battery or accumulator is the amount of energy stored according to specific temperature, charge and discharge current value and time of charge or discharge.

How does powering up affect battery life?

Powering up of a system also affects the life of the battery. During start-up, inrush current can occur due to the load capacitance. This spike of inrush current applies stress to the battery, decreasing its capacity. To minimize the inrush current, load switches implement a soft-start to control the rate at which the switch turns on.

How to get voltage of a battery in a series?

To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
