LITHIUM ION BATTERY TECHNOLOGY

Paper Published on Lithium Ion Battery Technology With Relay Control Switch And Micro Controller Based Voltage Monitoring System.

Lithium ion batteries are one of the most commercially used batteries. They are widely used in mobile phones, laptops and other consumer electronics, Electric Vehicles and Robotics concerns related to their safety and efficient operation still persists. In this work, we designed a lithium ion battery protected with battery management system (BMS) with inbuilt a radio frequency single relay channel controller that controls the power supply to external circuit and digital voltmeter indicated the rated voltage supply and we developed a micro controller based system that monitor the battery voltage. 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.

MICRO CONTROLLER AND SINGLE RELAY TIMER CONTROLLED LITHIUM ION BATTERY CHARGER

The development of Lithium Ion Battery Charger for charging lithium ion battery of series and parallel combination with constant current (CC) and constant voltage method (CV).

It is very important to know the battery charging parameters for correct charging like Voltage, Current and Cut off current.

Micro controller and Single relay timer switch controlled the battery from overcharging and monitoring the battery and responsible for regulating the voltage and current to Li-Ion Battery.

LITHIUM ION BATTERY WITH VARIABLE VOLTAGE TECHNOLOGY AND TEMPERTURE MONITORING SYSTEM

Design and developed a prototype of lithium ion battery all in one solution.A safe light weight battery for all portable devices. The rechargeable lithium ion battery with voltage regulator. The output voltage can be regulate from 12 Volt to 35 Volt and maximum output current is 6 Amps. The input voltage supply required for charging is 12.5 Volt to 13 Volt. A tiny and compact digital Battery SOC (State Of Charge) Indicator with LED Display for real time battery charging and discharging status. A modular system is also developed for monitoring of Li-Ion cell temperature during charging and discharging of battery.

Temperature monitoring systems developed to capture real time temperature data via a sensor such as a thermostat. The electronic temperature monitoring system to safeguard our products and satisfy regulatory demands. In lithium ion battery too low battery temperature will slow the charging rate while too high battery temperature will create a hazard. Maintaining the correct charging temperature range has the added benefit of increasing battery life expectancy. The ambient temperature in the immediate environment of the battery contributes heavily to the temperature of the battery during the charging cycle. Heat created by the chemical reaction of charging acts to increase the initial temperature of the battery. This lithium ion battery is protected from 12 Volt 40 amps Battery Management System (BMS) that monitors all the combination of cells in a lithium ion battery pack,Balance all the cells voltage equally and doesn't allow the cells from overcharged and protect the battery from fire and explosion.
