DC-DC Bidirectional Power Supply
Budget: $1,500 – $3,000 USD
* Bidirectional
* Buck/Boost
* In-1 40-60v
* in-2 10-60v
* current 0-100a
* RS485 Write: output current(current can be changed while the device is working), direction, output voltage, Work Mode: Power supply(provides constant voltage), Lithium charge mode (CC-CV) stop charging when absorption current gets to 5a
* RS485 Read: current, total Current from start, output voltage
*This will be used to transfer power between Lithium Batteries, so there should not be any problems if the battery connected on either of the outputs starts to become full and the input voltage will change.
*All required safety standards should be implemented correctly, The PCB design should be of nature that air can Flow from the front to the back without problems and provide adequate cooling.
*The power supply should record all data between stop and start, this also goes for accumulative AH In and out as well as direction.
*There should be a green LED for working, red LED for error, Green LED for one direction and another LED for another direction.
*The LED should all come on a separate PCB with the RS485 port. There should be an adequate connector selected to connect the 2 PCBs to each other.
*The unit should not overheat at all even when the ambient temperature is 30 degrees
*The Cooling fan should be PWM controlled and work according to temperature speeding up as the unit gets warmer.
*0% @ 25 degrees and 100%@ 35 degrees.
*The unit should be able to be paralleled with regards to communication so that data can be pulled from multiple devices over 1 line.
*Integrate an 8p Dip switch onto the separate PCB that can be used for addressing as well as other functions.
Use the first 6dips for addressing and the other 2 will be left open for programming.
*Have an ESP32 integrate (this may also be the main controller) so that there is the possibility of Wi-Fi and Bluetooth.
There should be an additional RS485 and CAN port on the front PCB that we can later use for of custom functions programming.
I am open to any other suggestions.
