When charging a battery, continuous power flow after the battery reaches full capacity can lead to overheating, overcharging, and eventual damage. This circuit automatically disconnects the charging source when the battery is fully charged, preventing further current flow.
This 12V auto cutoff battery protection circuit is designed to automatically disconnect the battery from the charging source when it reaches full charge, preventing overcharging and extending battery life. At the core of the circuit is the TL431, a programmable shunt voltage regulator that monitors the battery voltage.
By Girish Radhakrishanan The proposed over current cut-off power supply circuit using Arduino has 16 X 2 LCD display, which is used to show case the voltage, current, power consumption and preset threshold current limit in real time. Being an electronics enthusiast, we test our prototypes on a variable voltage power supply.
Full Charge and Shut-Off: The battery''s current demand reduces as it approaches its full charge level. As a result, there is almost no voltage differential across the resistor. The voltage at pin 2 now exceeds the voltage at pin 3 as a result of this modification.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
