Integrating an RV Battery Charger In My Solar Power System – Progressive Dynamics PD9140

The Portable Solar Power System is 7 years-old now and has grown and changed over that time. My system is not designed to power my home on an ongoing basis but to be there at a moments notice should we lose the power grid. My Solar Array is not mounted outside; it is mounted on cart wheels and rolled into my basement most of the time. Until now, most of my battery charging was with my Black & Decker Smart Battery Charger hooked manually to the battery bank twice per week.
When I demoed my Travel Trailer as while back, I was able to salvage my Progressive Dynamics model PD9140 40 AMP 600 Watt battery charger. This unit as installed in the trailer provided a 13.6 Volt constant charge to the trailer’s batteries. I recently purchased an add-on device called The Charge Wizard which turns this unit into a smart battery charger.
The Charge Wizard provides 4 modes of operation allowing the charger to remain running and charging continually based on the batteries current state of charge. The modes are:
* Normal Mode – 13.6 Volts
* Boost Charge – 14.4 Volts
* Storage Mode – 13.2 Volts
* Equalization Mode – 14.4 for 15 minutes every 21 hours.

I will be watching this like a Hawk for a period of time to ensure that I do Nothing to compromise my battery bank.

Battery charging model on matlab /simulink (CCCV charging)

Get the code from here:

A CCCV (Constant Current, Constant Voltage) is ideal for small batteries. Initially, the battery is charged at Constant Current. When the battery is nearly full, its voltage reaches the Constant Voltage setting of the charger, and the current decays exponentially as the battery gets a finishing charge.

In this model I have build a CCCV charger on simulink that simulates this effect can be used to study and simulate this charging method maybe in a bigger system.

A battery charger should not be mounted in a place which could get wet or directly above the batteries. The battery charger should be mounted as close to batteries as possible.
