Hoover Vacuum Battery Fix

Post by methods » Jun 24 2018 2:10pm

I had a nice review thought up...
Then I remembered how F'ed the world is

This is how I fixed mine after our Accounted wasted HOURS on the phone with the totally inept "process" which insisted that the problem is with the battery and not the charger (or combo)

* Batteries discharge fine
* Battery BMS has kept the cells in perfect balance
* Batteries do not charge on the charger

I crow-barred the charge inhibit fet
I crow-barred the discharge inhibit fet (to avoid charging thru its body diode)
I gutted the charger and hard-wired it to a Dell 19.4V laptop charger

Yea yea.. dont care
Here are some pics

/...

There ya go
Now think about the EV industry...
Think about Autozone
Think about how many people are going to hack their cars like this

IT WILL BE THE ONLY CHOICE
THEREFORE ALL CHARGING INFRASTRUCTURE MUST BE ... compatible

DO NOT ASSUME - that EV's (or any Lithium Electronics) are "to spec"
Quite the oposite

Increasing battery voltage and controller current limit will result in a non linear experience
