IS 800V REALLY THAT MUCH BETTER? YOUR ELECTRIC CAR QUESTIONS ANSWERED! EV INBOX EP. 1

EV Channels Review

In the inaugural episode of 'EV Inbox,' Kyle Conner delves into complex EV topics, prioritizing technical depth over basic range discussions. The primary focus is the 800V architecture, exploring its advantages and disadvantages. Conner highlights that while 800V systems reduce charging losses and enable faster charging by allowing higher power delivery at lower amperage, the cost and complexity of interfacing with legacy 400V infrastructure are significant drawbacks. He notes that component availability has improved, diminishing the initial cost disadvantage. The review also touches upon the rising cost of public DC charging, attributing it to demand charges and the business model shift from enthusiast support to profit-driven operations. Conner advises against unnecessary use of Tesla's cabin overheat protection, deeming it a comfort feature with minimal impact on battery longevity. He also explains thermal derating, identifying inverters and charging cables/ports as common culprits, and praises Porsche's Taycan for its well-engineered cooling system that supports its aggressive charging curve.
