I’m seeking advice and insights regarding the DC fast charging performance of my 2024 Blazer EV LT trim. Despite being rated for faster charging speeds, I’ve been experiencing consistent issues with charging rates on DC fast chargers. Here’s a detailed breakdown of the situation:
Issue Summary:
- Tested at both a 125 kW ChargePoint station and a 350 kW Electrify America station.
- Regardless of the battery percentage or state of charge (SoC), the charging speed maxes out below 30 kW, even with preconditioning enabled.
- Attached images from a recent Electrify America session (both app and vehicle dashboard) show speeds below 30 kW, despite the station supporting up to 350 kW.
I had the car inspected, and the service report stated that the charging system had no faults. Their note mentioned:
While they concluded that charging was functioning “as expected,” the performance falls short of Chevrolet’s stated specifications.
Manufacturer's Claims vs. Observed Performance:
- Chevrolet claims that the Blazer EV LT trim supports charging speeds up to 150 kW.
- The official website highlights that the Blazer EV can provide up to 80 miles of range in 10 minutes of DC fast charging.
- Tested multiple charging stations and terminals.
- Ensured preconditioning was enabled during charging.
- Has anyone else with a 2024 Blazer EV experienced similar DC charging speed issues?
- Are there any known factors (e.g., software updates, station compatibility) that could explain these reduced speeds?
- What steps should I take next to ensure this issue is properly addressed by Chevrolet?
Attachments for Reference:
- Images from recent Electrify America session (app and vehicle dashboard).
- Expected charging curve for the Blazer EV.
