Episode notes
Complexity Outside Tesla Creates Reliability Gaps
- Non-Tesla DC fast charging is far more complex because hardware, networks, and carmakers must interoperate.
- Tesla's vertical integration simplifies charging and gives it a major reliability advantage.
Boom, Pop, Then A Dead EV
- Several drivers heard a loud boom while fast-charging and then found their cars dead and needing tow trucks.
- Two cars had circuit breakers reset or replaced while one Bolt was taken by a dealer and later totaled by insurance.
Circuit Breakers Trip To Protect Batteries
- The boom usually signals a protective circuit breaker tripping from an anomalous power event.
- That breaker protects the expensive battery but can leave drivers stranded and cars disabled.
