What is battery capacity?
So, let’s start learning about the very important concept of “Battery Capacity”. Battery Capacity is defined as the product of the electric current flowing in or out of the battery in amperes and the time duration expressed in hours. Battery Capacity influences the time for which a device can operate without using power from any other sources.
How much power does a battery consume?
The average power consumption of such a device depends of course on the usage model but it is not uncommon to be in the 1–2 W range a tenfold increase with respect to only few years ago. On the contrary the energy density of the batteries only increased by a factor of two.
What happens when a battery charge is near the maximum capacity?
When the battery charge is close to the maximum battery capacity then the charger current starts to decrease (Fig. 9.3). The end of charge is set to a current that depends on the battery and on the required battery capacity. Typical values for Li-ion batteries are in the range from 0.01 C to 0.1 C.
How to calculate battery capacity?
Battery Capacity (in Ah) = (I × t) / 3,600 Which is the required formula. There are various factors that affect the battery capacity such as the chemistry of the substances used in the making of the battery to external factors such as temperature. Let’s discuss these factors in detail as follows:
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 much power does a mobile phone use?
On top of it the communication technology and connectivity expanded from 2G to 2.5G, 3G, LTE, WiFi, BT, NFC not to forget GPS and FM radio. The average power consumption of such a device depends of course on the usage model but it is not uncommon to be in the 1–2 W range a tenfold increase with respect to only few years ago.
