Mercedes-EQ and Plug-in Hybrid Repair: EQS, EQE and 48-Volt Systems

Repair considerations for Mercedes-Benz EVs, plug-in hybrids and mild-hybrid 48-volt models, from high-voltage shutdown to battery inspection.

Three Levels of Electrification

Mercedes-Benz sells fully electric vehicles such as the EQS and EQE, plug-in hybrids on models like the GLC, and many gasoline models with 48-volt mild-hybrid systems. Each level affects collision repair differently.

Fully Electric Models

EQ models carry large battery packs under the floor. Repairs start with disabling the high-voltage system following Mercedes-Benz procedures. Side and underbody impacts require careful battery inspection.

Plug-in Hybrids

Plug-in models combine an engine with a sizable battery. Technicians identify and protect high-voltage components near the damage, and the charge port is inspected after nearby impacts.

48-Volt Mild Hybrids

Many current Mercedes models use a 48-volt electrical system with an integrated starter-generator. It is lower voltage than an EV, but it still requires correct disconnection and post-repair checks.

Paint and Heat

Paint curing temperatures are managed to protect batteries, following manufacturer guidance.

Frequently Asked Questions

Is a 48-volt system dangerous?

It requires care but is far lower voltage than an EV battery.

Can you repair an EQS?

Non-structural repairs, yes. We'll advise if any operation requires a Mercedes-certified facility.

Does an EV need more calibration?

Calibration depends on the sensors affected, not the powertrain.
