To achieve intelligent monitoring and management of lithium-ion battery charging strategies, techniques such as equivalent battery models, cloud-based big data, and machine learning can be leveraged.
In theory, a linear battery charger with a sepa-rate power path for the system is a fairly simple design concept and can be built with an LDO adjusted to 4.2 V; a current-limit resistor; three p-channel FETs to switch the system load between the input power and the battery source; and some bias parts.
The following graph suggests the ideal charging procedure of a standard 3.7 V Li-Ion Cell, rated with 4.2 V as the full charge level. Stage#1: At the initial stage#1 we see that the battery voltage rises from 0.25 V to 4.0 V level in around one hour at 1 amp constant current charging rate. This is indicated by the BLUE line.
Lithium-ion batteries are susceptible to deep discharge or overcharge, affecting their performance and lifespan . Therefore, in applying lithium-ion batteries, the battery charging system must be well designed to get high battery performance and long battery life .
6 W and R2 (RSystem or battery) will use 4 W. One can see that, for a linear charger with a 10-V input and 4-V output, only 40% of the energy will be delivered to the system or battery. The linear design does not require an inductor or diode and is generally less expensive than a switcher for low-power, low-dissipation designs. As power demand
The recommended solution is to power the system directly from the input source, when it is available, and at the same time to charge the battery from the input via the charger. This allows the charger to be dedicated exclusively to the battery without any external disturbances.
