난이도 & 준비물
증상
배터리 테스트 시 표면 충전(surface charge)으로 인한 거짓 양성 판독값 발생. 배터리 전압이 약간 높게 나타나고 충전 상태(SoC) 읽기가 부정확함.
처리 내용
표면 충전은 납축전지가 황산납을 납과 이산화납으로 빠르게 변환하지 못해서 발생하는 현상으로, 대부분의 충전 활동이 플레이트 표면에서만 일어나기 때문입니다. 이로 인해 배터리 외부의 충전 상태가 높아져 있습니다. 표면 충전은 가역적이므로 제거 가능합니다. 제거 방법: 배터리 용량의 약 1%를 방전시킬 수 있도록 전기 부하(예: 헤드라이트 몇 분간 켜기)를 켜거나, 배터리를 몇 시간 동안 휴식시키면 됩니다. 표면 충전은 배터리 결함이 아니며 완전히 가역적인 현상입니다.

BMW 5시리즈
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
