CTEK 7002. as a PSU

F32Fleet · 02-14-2022, 01:26 PM

Has anyone tried using this charger as a PSU for coding/programming?

Per the manual the supply mode provides 13.6 volts which is allegedly whay BMW requires.

Thoughts?

it's not the voltage you need, but Amperage. how many amps does it provide?

7

My guess is nowhere near enough.

you need at least 20, but 50-100 would be the best.

A battery charger is not a programming power supply. The difference is ripple voltage. A charger puts out very dirty voltage that fluctuates. A programming power supply does not do that. It is a very clean, solid voltage supply. Minimial ripple.

It's not all that bad, and besides, the battery will smooth any ripple.

Try one of these. I got a 60 amp model for not much more than a 100$. Used it yesterday for a nav map update. 45 minutes on battery with headlights on, no problem
You just need to clip the ends of a pair of jumper cables and screw them in to the terminals
