Lithium Ion Battery Variable Voltage Technology with Single Relay Control and Temperature Monitoring System

Lithium ion batteries are one of the most commercially used batteries. They are widely used in different gadgets like mobile phones, laptops, electronic gauges and devices, Electric Vehicles and other consumer electronics, Electric Vehicles, Robotics and other devices concerns related to their safety and efficient operation still persists. In this work, we designed a lithium ion battery technology protected with battery management system (BMS) with inbuilt a radio frequency single relay channel controller that controls the power supply to external circuit, A voltage regulator with variable potentiometer that regulates the voltage output from 12 Volt to 35 Volt and digital voltmeter indicated the rated voltage supply. A battery SOC (State Of Charge) indicator for charging and discharging status of battery. We also developed temperature monitoring system that monitor the Li-Ion cell temperature during charging and discharging of battery. We expect the proposed strategy and technology improve battery capacity and prolong lifespan. This Lithium-ion battery have the characteristics of high-power density, long life, low self-discharge, low maintenance costs and low environmental impact. However, lithium has high reactivity, so there are technical limitations related to the safety of building batteries.
