Dear sir,
We have designed a BMS with 6s configuration with each cell can charge maximum up to 4.2 V resulting overall BAT voltage to 25.2 V. Actually, I have one doubt related to waking a BMS from shutdown mode. In EVM design, there is wake up switch when you press that 7 cell voltage applied to pack voltage and bms wakes up ( If I am right ) I have also attached EVM guide image below.
But in our design there is no provision of switch instead of that we are just shorting R3 terminal to wake up it as you can see from attached image,I had attached my schematic design for reference.
But for our application purpose we have enclosed our BMS inside a pack so now we don't have provision of R3 terminal. Only exposed terminal which we have are PACK,GND,SCL,SDA,GND, as you can see from attached image. Now I am waking up my bms from shutdown by connecting pack and gnd to power supply and supply voltage set to 25.2 V and BMS in these case does get wake up. But I want to know whether these process is right of waking up my bms which i am doing currently? it will not damage my bms ? If wrong please can you suggest me other way waking up. I have attached below image for reference you can check.
Waiting for your reply,
Regards,
Shubham
