6 FAQs about [Shared power supply for lithium battery charging]
What is a battery charger with load sharing?
This article goes through creating a battery charger with load sharing (also known as power-path) that can properly charge the battery and have the main circuit run normally. The charging IC we’ll be using is the popular MCP73831/2 from Microchip for single-cell Li-Po and Li-Ion batteries with a maximum charge current of 500mA.
Why does a battery charging system need a few parts?
Still only requires a few parts. Allows the system to be in use while charging. The load is at risk of overloading the input charging supply, causing damage. The system must know when it is charging, complicating system design. Requires the system to account for the differences in voltage between the input supply and battery.
When does system load take priority over battery charger?
When the system load and the battery draw more energy than the supply can offer, the system load takes priority over the battery charger. Definition: The theoretical capacity of a battery is determined by the amount of active materials in the battery.
What is a system load battery?
System Load Battery supplies system load when power source is absent. Typical Portable Power Source. Typical System and Battery Load Sharing Application. This application note shows how to design a simple load sharing system using Microchip’s popular MCP73837 device for cost-sensitive applications.
What is load sharing power path control?
The load sharing power path control (Q2, D1, R6) interrupts the connection between the battery and the load when an external power supply is connected. In this case, the load is powered by the external power supply while the battery is being charged. This protects the battery and increases its lifespan.
How does a battery-powered system work?
The daily battery charging frequency increases, and it becomes important to operate a device while charging its battery. The traditional method to design a battery-powered system is to connect the system load directly on the battery. The system load continuously discharges the Li-Ion battery and costs a battery’s life cycle.
