Tesla owners in deep freeze discover the cold, hard truth about EVs
Extreme cold snaps exposing Tesla drivers to dead batteries and unusable chargers have reignited debate over how well electric vehicles cope in harsh winter conditions. Commenters compare EVs with gasoline and diesel cars—both of which also struggle in subzero temperatures—while highlighting specific weaknesses like reduced range and cold‑sensitive charging, as well as mitigations such as heat pumps, battery conditioning, and plug‑in hybrids. The broader question is whether current EV technology and infrastructure are mature enough for very cold climates, or if alternatives and design changes are still needed.
Cold-weather impact on EVs and ICEs
- Many note that all vehicles struggle in extreme cold: diesel gelling, frozen gas pumps, dead 12V batteries, need for block heaters, engines left idling.
- EVs lose range in cold; one graph for a Tesla S100 shows up to ~30% reduction. Owners of various EVs confirm noticeable range loss even with heat pumps.
- A specific failure mode highlighted: if the pack is too cold, some EVs (especially Tesla) can’t fast‑charge until the battery is warmed, which itself consumes battery energy.
Charging failures and proposed mitigations
- Several argue Tesla should heat packs using power from the charger, not from the pack.
- Suggestions include indoor charging bays in cold climates, or EVs with continuous battery conditioning via heat pumps. Concerns raised over cost and throughput of indoor stations.
- Some report that cold-related Supercharger outages around Chicago might be infrastructure or grid related, not inherent to EVs, but this is disputed and unclear.
Extreme-climate edge cases
- Multiple comments describe −30°C to −60°C conditions where any vehicle can fail; ICE vehicles may be left running for days.
- Debate over how relevant these scenarios are: some see them as rare edge cases; others stress that in remote northern regions, failure is life‑threatening and EVs must be judged by that standard.
User experience and reliability
- Some EV owners say winter usability is better than ICE: reliable starts, easy preheating, always leaving home with a “full tank,” and good traction control.
- Others report worry about battery drain when parked in the cold (e.g., grocery trips), and dislike loss of range and slow charging.
- Conflicting claims on reliability: some long‑term EV owners report minimal issues; others say current EVs are less reliable and more expensive than ICE for typical consumers.
Hybrids and plug‑in hybrids (PHEVs)
- Strong thread arguing plug‑in hybrids avoid many cold‑related and range‑anxiety issues while providing most EV benefits.
- Counterpoint: PHEVs duplicate systems (engine + EV), adding complexity and weight. Supporters respond that smaller batteries offset this, and PHEVs are still lighter than many full EVs.
- Some discuss series vs parallel hybrid architectures and efficiency trade‑offs.
Environmental and grid impacts
- One side stresses EVs’ lifecycle emissions are lower and that battery recycling volumes are lower than expected because EVs last longer than predicted.
- Others note higher manufacturing footprint and argue that walking, biking, car sharing, and public transport are the real climate solutions.
- Concern that EVs will raise electricity prices is met with counter‑claims that smart charging and using surplus renewables could lower prices; critics say this assumes expensive, not‑yet‑built infrastructure.
Media tone and “hit piece” accusations
- Some see the article as anti‑EV FUD; others insist pointing out cold-weather weaknesses is legitimate criticism.
- Discussion of The Register’s long‑standing snarky style (e.g., calling X a “hellsite” and other nicknames) and whether that conflicts with journalistic objectivity.
