What constitutes a discharge cycle?

How a battery discharge process is performed in safe conditions?

For the discharge process to be performed in safe conditions, besides gathering information about the battery’s capacity, SoC and SoH at the beginning of the process it is necessary to monitor the temperature and voltage of individual modules, preferably even groups of cells, as well as to control the discharge current.

What is a high discharge lithium ion battery?

High discharge lithium ion batteries are a great way to power any R/C, robotic, or portable project that needs a small battery with a lot of punch. Nominal Voltage - These have a nominal voltage of 7.4V and like the round cell batteries, do NOT have a built in protection circuit.

What is the flow of discharging current from a battery?

the flow of discharging current (i.e. current from the battery) into the load. Shown are examples. Irrespective to the protection implementation on high or low side, either source-to-source or drain-to-drain configurations are possible. Inrush currents arise during the turn on, mainly when the battery is first connected to the load.

What happens when a battery is discharged rapidly?

When being discharged rapidly it can appear that the entire battery energy was consumed when the voltage drops to 0 V, but due to slow chemical reactions within the battery after the load has been disconnected from the battery, minutes to hours later, the voltage on the battery can recover, even over the critical 2.5 V.

What percentage of a battery is fully discharged?

Batteries are seldom fully discharged, and manufacturers often use the 80 percent depth-of-discharge (DoD) formula to rate a battery. This means that only 80 percent of the available energy is delivered and 20 percent remains in reserve.
