High-Voltage Battery Diagnostics in Riverside, CA
Traction battery health checked by technicians trained on HV systems and factory de-energizing steps.
High-voltage battery diagnostics measure the health of an eSprinter's traction pack and pin down why a last-mile fleet van has lost range or power. This is high-voltage work, so our Yorba Linda technicians follow factory de-energizing and safety steps before touching the pack. We read the battery management system with factory tools, test cells and modules, and locate faults without guessing.
What this service includes
- Factory-procedure de-energizing before any high-voltage work starts
- Battery management system readout of cell voltages and temperatures
- State-of-health and capacity testing to explain lost range
- Isolation and insulation resistance testing for HV faults
- Module and cell-group fault location inside the pack
- High-voltage connector, fuse, and contactor inspection
Who this is for
- Your eSprinter has lost noticeable range on its daily routes
- A high-voltage or battery warning is showing
- Charging has slowed or the van is limiting power
- You want the traction battery checked before adding a used van to the fleet
Frequently asked questions
Is it safe to diagnose an eSprinter's high-voltage battery?
Yes, when it is done properly. Our technicians are trained on high-voltage systems and follow Mercedes de-energizing and personal protection steps first, so the pack is safely isolated before any testing begins.
Why has my eSprinter lost range?
Range loss can come from cell degradation, a weak module, a thermal management issue, or a charging fault. We read the battery management data and test the pack itself to find the real cause instead of assuming the whole battery is worn out.
Can you check pack health before I buy a used eSprinter?
Yes. We pull the state-of-health data and test the pack so you know the true condition of the traction battery before you add a used electric van to your Inland Empire fleet.
