증상

MkV 골프가 2개월 전 폭스바겐 딜러에서 대규모 정비를 받았을 때 배터리가 양호 판정을 받았습니다. 오늘 아침 시동이 걸리지 않았고, 충전기로 약 1시간 충전한 후 Kwik-fit에서 진단 결과 배터리 EN(A)가 281(정격값: 570)로 측정되었습니다. 교체를 권장받았습니다. 2개월 만에 이렇게까지 성능이 저하될 수 있을까요? 2008년식 차량의 순정 배터리입니다.

처리 내용

노후 배터리가 하루는 정상 작동하다가 다음 날 갑자기 시동 불능 상태가 되는 것은 흔한 현상입니다. 배터리는 전기 부하가 없어도 자연적으로 방전됩니다. Bosch 자동차 핸드북에 따르면, 납-안티몬 합금을 사용하는 신규 배터리는 신제품 상태에서 매월 약 4~8%의 방전이 발생합니다. 배터리가 노후화되면서 음극판으로의 안티몬 이동 및 기타 불순물로 인해 이 수치가 일일 1% 이상 증가할 수 있으며, 결국 배터리가 완전히 기능을 잃는 시점에 도달합니다.

Go woke go broke. What's the point of Jaguars USP when any old Chinese EV maker can give you a super smooth 500bhp car with effortless torque and eery refinement for under £50 grand? When Tesla gives you much the same with the added benefit of a luxury charging network? Would it just be beauty?That's about the only thing they could possibly conjure as a point of difference but I doubt they can comply with a myriad of technical parameters for a global car AND make something gorgeous looking. The only way of making something quite different would be to not package the battery as a skateboard
