LV124 / LV148 Electrical Current Consumption of Automotive ECUs

How much current does your ECU need? Let’s compare notes!

In our second post on electrical behavior of automotive ECUs, we dive into real-world current ranges and categorize ECUs into:

Category 1 (<25A): Sensors, control units, comfort modules
Category 2 (<80A): Pumps, fans, heaters, electric steering
Category 3 (>80A): Starters, mild hybrid drives, DC/DC converters

Our fully automated #RTStand #LV124 / #LV148 test systems support testing for these types, across 12V, 24V and even 48V platforms.

I’m curious:
Are your current profiles similar?
Do you already face challenges with >80A systems?
Is current consumption a key topic in your test strategy?
Let’s share experience — I’d love to know whether our observations align with yours or if you see other trends in the field.
