Lithium ion Charger, Discharger and Analyzer

Features

• Charge a single Li-ion cell upto 1A
• Discharge from 0.1 to 1.3A – adjustable discharge rate
• Analyze voltage, current and temperature readings at high sample rates and accuracy
• On-board OLED display for diagnostics
• 3 LEDs for the on-board charger status
• Reverse polarity battery protection and LED indication
• 2 user programmable LEDs

It is compatible with the STM32 Nucleo series boards as well as Arduino Uno R3.

This board can be used to learn more about –

• How to prevent undervoltage during discharging
• How to prevent overvoltage during charging
• What is SOC and how to design its computation algorithm
• What is SOE and how to design its computation algorithm
• Effects of temperature on a Li-ion cell
• Capacity fade of a Li-ion cell
• What happens to a Li-ion cell during storage
• What causes fires in Li-ion cells and how to prevent them
• How to deal with overcurrent conditions for a Li-ion cell
