What is battery management in a mobile device?

In fact, most of the power loss happens in the power source that continuously runs in its current limit region. Essential part of battery management in a mobile device is the monitoring of the state of charge of the battery. All the algorithms that perform this task go usually under the name of “Fuel Gauge” algorithms.

How will future battery technologies affect mobile devices?

Future battery technologies will provide more capacity per volume and extended voltage range but also will pose more challenges for the electronics that needs to supervise and monitor the battery behavior as the power demand of the mobile device will further increase. 1.

Why do we need multiple battery cells?

They are particularly demanded in the emerging technologies of vehicle electrification and renewable energy integration for a green and sustainable society. To meet various voltage, power, and energy requirements in large-scale applications, multiple battery cells have to be connected in series and/or parallel.

What is a switched mode battery charger?

Switched mode battery chargers use switching regulators to control both current and voltage. They achieve high efficiency therefore limiting the power dissipation in the chargers. They also can optimize the power transfer from the source to the battery reducing the charging time.

Can wearable embedded energy sources be used to charge mobile phones?

This research proposes to develop wearable embedded powered energy sources for charging mobile phones as a backup for instant and seamless charging of the phone battery once it drains.

What algorithms are used for battery monitoring in a mobile device?

Essential part of battery management in a mobile device is the monitoring of the state of charge of the battery. All the algorithms that perform this task go usually under the name of “Fuel Gauge” algorithms. This section describes the three main algorithms used for a battery monitor system for cellphone applications.
