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.
Among them, the lithium-ion (Li-Ion) battery is widely-adopted because of its high energy density on both a gravimetric and volumetric basis.
This method was commonly used in lithium-ion batteries until about 5 years ago. The most common method to do gauging is to use impedance track-based fuel gauges. These ICs actually measure the impedance on the cells and track it over time, temperature, and usage patterns.
The power supply system should operate at high efficiency at the nominal load current. Some systems have to operate in a standby mode where the load current is reduced to a few milliamperes or even down to the microampere range when no backup batteries for RAM and real time clock are used.

Batteries can be charged manually with a power supply featuring user-adjustable voltage and current limiting. I stress manual because charging needs the know-how and can never be left unattended; charge termination is not automated. Because of difficulties in detecting full charge with nickel-based batteries, I recommend charging only lead and lithium-based batteries …

Hi folks, I''ve been spending the weekend researching this topic and bumped into this topic which seems to have raised similar issues to those I raise below. BTW, my electronics skills are close to zero. My objective is to have load sharing capabilities to allow me to build (I have already built one) a series of Sonos type WiFi speaker using the Pi Zero and the Hifiberry …
Design Considerations for the 48V 100AH Lithium Battery Backup Power Supply. 1. Safety Design. Safety is of utmost importance in the design of the backup power supply. The lithium battery pack must be designed with proper enclosures to protect against physical damage. Additionally, the BMS should have robust safety features to prevent thermal ...
Set the power supply to the highest voltage that the system is rated at and measure the current, then set the power supply to the lowest voltage that the system is rated at and record that current. Adding a measurement half way between the two will give you an idea of where the lowest power consumption point is (power is voltage times current). The idea is that …

Lithium-ion battery manufacturing demands the most stringent humidity control and the first challenge is to create and maintain these ultra-low RH environments in battery manufacturing plants. Ultra-low in this case means less than 1 percent RH, which is difficult to maintain because, when you get to <1 percent RH, some odd things start to happen.
