In Progress

Solar Charge Controller

We have a Solar Charge Controller design which we need modified. The existing design is solid but we need some changes and then I need the PCB layout redone. Basic information on the existing charge controller is:

1. Microprocessor based

2. PWM Charge controller

3. Load switch - MOSFET

4. Current Measurement (in battery circuit) – ADC into microprocessor

5. Voltage measurement – ADC into microprocessor

6. Temperature measurement – ADC into microprocessor

7. USB communication

8. iButton communication

9. E2 memory

10. RTC Date Calendar

The new charge controller is to have similar functions with the following additions:

1. Additional current measurement in the load circuit - ADC

2. Bluetooth connectivity

3. Keypad connectivity.

4. Minor changes/modifications - TBA

Your responsibility will be to:

1. Analyse the existing design and ensure you understand it completely.

2. Do the new electronic design and simulation in Proteus 8.0. The design is to include the calculation of the A2D factors and calibration methodology.

3. Once the design has been approved you will be required to do the PCB layout. Note that the PCB layout will be for two PCB’s. The first PCB will be the microprocessor and its associated components (low power) and the second PCB will be the MOSFETs, heatsink etc (power components). The two boards will be joined through a ribbon cable. Gerber files are to be provided. The PCB’s will be double sided. Surface Mount Technology will be used.

4. Component list with suitable alternatives where necessary.

You will NOT be required to:

1. Do any microprocessor programming. We will provide the micro specification and pin layout.

2. Make prototypes.

A more detailed specification and the existing design will be provided once a NDA has been signed.

For now please provide a cost per hour, experience, plus estimate of hours. We will fine tune once a full spec has been provided.

Also note that this is an extremely urgent project. Please indicate resource availability and estimated time.
