Talk:Mercedes-Benz Vision EQXX

Explanation of cable heating loss
Section Battery and powertrain says "thinner cabling reduces leakages caused by Joule heating". It's really rather the opposite: thinner cabling increases heating all things being equal, because its resistance would be higher. The right explanation is that the 900 V electrical distribution system allows lower current for a given power level, and it is the lower current which then allows the use of thinner cabling without unacceptable Joule heating losses. ☆ Bri (talk) 17:50, 23 January 2023 (UTC)


 * @Bri Hi, does the mention of lower amperage in the preceeding clause not clarify this? Please let me know if this should still be changed. X750. Spin a yarn? Articles I've screwed over? 18:45, 23 January 2023 (UTC)
 * If you mean the phrase that now reads (after my copyedit) "The EQXX also uses a 900-volt architecture, which allows for a lower electric current", no, sorry, I don't think this is sufficient and the statement that thinner cabling reduces losses is flat out wrong. High voltage reduces current, which is correctly stated, but then it should be restated by going on to say that reduced current allows reduced I2R losses in relatively thinner distribution cable. ☆ Bri (talk) 19:27, 23 January 2023 (UTC)
 * I've redone the section. Tell me what you think. X750. Spin a yarn? Articles I've screwed over? 19:55, 23 January 2023 (UTC)
 * It looks pretty good now. I might go tweak it later after thinking about it some more. ☆ Bri (talk) 20:02, 23 January 2023 (UTC)
