What is SMBus?
Some higher-end battery packs are given the ability to communicate with the outside world over a link known as SMBus. These packs store information about their usage history and how much energy they presently contain, which can then be shared with the host equipment. When charging, these packs can inform the system what charge parameters to use.
What is the difference between nominal voltage and charge voltage?
As a battery is discharged, its voltage will slowly decrease until the pack is nearly empty. Further discharge will cause the voltage to fall rapidly to zero. When the pack is recharged, the opposite profile will occur (more or less). Batteries are usually specified as having a nominal voltage near the middle of this profile. From the point of view of charging, however, it is more important to know the maximum allowed voltage for the pack. This is referred to as the charge voltage. For example, lithium ion cells typically have a nominal voltage of 3.6V, but the charger must push them to 4.2V (the charge voltage) before they are considered full.
What is a thermistor and how is it used in charging?
A thermistor is a small, inexpensive electronic component that can be used to measure temperature. They are often incorporated into battery packs as a safety device or as a means of monitoring the charge profile of the pack.
