This is the most basic, convenient, and lowest-cost charging method, forming the cornerstone of electric vehicle adoption. In detached homes, owners can install private charging piles to utilize off-peak electricity at night. The main challenges lie in power capacity expansion in older residential areas and apartment buildings, and coordinating parking space ownership and property management. Solutions include promoting shared private charging piles, building public charging stations, and implementing intelligent and orderly charging in communities to alleviate installation conflicts.
