Recently I got the meepo hurricane and it was awesome!! For like 2 days…
After those 2 days it stopped charging and after inspection I knew that the charging module was broken.
I already contacted meepo about it but as they are in holidays I expect them to deliver me the spare parts in more than a month or so.
My question: do you know were I can get buy a spare charging module that I can use to replace the broken one? I’m based in germany.
Thanks guys!
its fine, it was Marcel’s idea to cut it open and have a look, but we still don’t know what it does. im planning to bypass it at some point to see what happens
Perhaps.
It’s “dumb” unless there is an MCU on the back so its functionality will be limited to one or two primary uses. It could be over/undervoltage protection, electronic fuse, or AS-type functionality (inrush related stuff).
Really good photos of the front and back (so the chip numbers can be read) would help a lot.
It isn’t BMS related (cell level at least) since it only appears to measure pack voltage. Though I guess it can be argued that a pack protector is still a type of BMS, even if it doesn’t do cell-level measuring, balancing, and protection.
Interesting, thanks.
Only enough components for perhaps dividing down the voltage then and perhaps taking action at a certain voltage. No current sensing resistor, it appears, to do over-current stuff but it’s hard to see with that photo.
Your charger is a-ok then. Also we have the same multimeter I think lol. 12s chargers should be 50.4-51v (Hopefully the BMS cuts off charging at 50.4v)
