[[How to find short circuits]]


Inject 1 V (increase if no reaction), watch for hot spots with thermal cam. Usually it's a bad tantalum cap on the PPBUS_G3H rail.
In the early 2010s, the US DoE funded a program (the "EV Project") to help solve the chicken-or-egg problem of public charging infrastructure vs EVs to use them. They seeded the country, in several markets, with Level 2 charging stations that used the heavy duty PE-30 model.

Ethanol used instead of thermal cam with 0.8 V on PPBUS_G3H, resistance between PPBUS_G3H and CPU coil is 3.6 Ω) Example 2: <nowiki>https://www.youtube.com/watch?v=TZsvvUWUInE</nowiki> (Taking 20 V, 20 mA.

!Model number
Read the resistance from PPBUS_G3H to Vcore coils (coils around CPU/GPU) IF those measure UNDER 1 Ω (0.3–0.8) then you most likely have a direct 12 V short to CPU/GPU. On this board this situation is always a no fix.

This page documents the Ecotality PE-30 EV charging station. This was a robust pedestal for public use, encapsulating the WE-30 hardware that Ecotality made for home use.

In the early 2010s, the US DoE funded a program (the "EV Project") to help solve the chicken-or-egg problem of public charging infrastructure vs EVs to use them. They seeded the country, in several markets, with Level 2 charging stations that used the heavy duty PE-30 model.
