battery-charger

A custom battery charger using a dc programmable power supply (FCCT 400-40-I from supplier.ind.br)

Development Roadmap:

• implement modbus communication with the power supply
• implement custom waveform generation
• implement voltage and current measurements
• implement capacity and energy computations
• transfer states to a json config file
• transfer charge_program to the json config file
• add the json config file as an argument from command line
• implement a configuration for verbosity as an argument from command line
• implement the TCP IP and PORT as an argument from command line and in the json confg file
• implement a csv log to a file (which the name sould be passed as an argument from command line)
• implement a report to txt file
• callibrate voltage and current setpoint
• callibrate voltage and current measurements
• test with a battery
• integrate an Arduino Uno with temperature + smoke sensors
• implement a relay + fuse + connectors + buzzer PCB as a shield for the Arduino Uno
• supplier.py as a library

Dependencies:

pyModbusTCP == 0.1.7

Setup for development:

• install dependencies

To test without a power supply:

• configure SERVER_HOST string as localhost
• runsudo ./dumb_modus_server.py
• run ./battery_carger.py

To test with a power supply:

• Turn your power supply on and configure its ethernet address
• configure SERVER_HOST string to the power supply ethernet address
• connect resistors to the power supply output
• plug your oscilloscope
• run ./battery_carger.py
