What is the difference between Li and i?
2 Answers
L stands for Large in English, meaning big or extended. i represents gasoline direct injection, and Li stands for extended version with gasoline direct injection. Taking BMW Li and BMW i as examples, the differences are explained in detail: BMW Li is a model with an extended wheelbase, while BMW i is the standard wheelbase model. Wheelbase is the most fundamental factor affecting passenger space. A longer wheelbase increases the longitudinal space for passengers, significantly enhancing the legroom that affects the comfort of vehicle seating. The BMW Li model better meets the psychological standards of Chinese consumers and offers more thoughtful humanized design for rear passengers, making it suitable as a business vehicle that balances both family and commercial use. Generally, Li is more expensive than i.
Recently, when discussing cars, many of my friends couldn't distinguish between the concepts of lithium and electric current. Lithium, for instance, is like the raw material in batteries—a chemical element used to store electricity, commonly found in modern electric vehicle lithium batteries. Electric current, on the other hand, refers to the quantity of electricity in motion, akin to the flow rate of water in a pipe; when you turn on an electrical device in the car, current flows. The difference lies in the fact that lithium is a tangible substance, while current is an action and a process. In everyday car usage, understanding this is practical—for example, lithium battery quality affects driving range, and unstable current may cause lights to flicker or even blow a fuse. During maintenance, it's essential to ensure lithium batteries aren't overcharged or over-discharged, and that the current doesn't exceed safe limits. In short, the two are related but fundamentally different—lithium provides the energy source, while current transmits the energy flow.
