The Pros and Cons of Lithium-Ion Batteries for UPS Systems
Re-Charge Speed: Charging either a li-ion or lead-acid battery to 80% takes roughly the same amount of time. But li-ion systems do have an advantage beyond that charge capacity. Reaching a 100% state of charge for lead acid batteries can take more than five to ten hours, while a li-ion battery can reach that state in 30 minutes to an hour.
Working Explanation This circuit is constructed to charge the Li-Ion battery cell with variable current output. As shown in the circuit, the four-terminal select switch is employed to change the charging current. Here as we have used IC MCP73831/2, this IC employs a ...
