Hi I'm having some issues designing a circuit for a project I'm working on.
It's a 48v Ebike battery but im including USB C charging so i can charge my phone on the go and i was thinking of including the option of charging the battery pack via USB C in case i dont have the normal charger for the pack. all that being said i bought a IP2368 USB C charging board (Link)
I also have a step down Converter (Link) to convert the 48v to 12v a voltage the charging circuit can handle.
Then i bought a boost converter (Link) so that when im trying to charge the battery pack via USB C i have a charge voltage
i also bought some Diodes (Link) because i want to keep the power when trying to charge the pack via USB C from back flowing through the Step Down Converter. In all honesty this is where im kinda stuck I know that the IP2368 needs to have the 12v signal from the step down to monitor the battery voltage so it knows its not over charging my BMS will cut off power incase of too low or high of a voltage. i completely burned through some small wire during a test and i dont know exactly where to put the diodes in the circuit. If anyone could offer some advice that would be great.
Thank your for your help.
