During normal driving, if the fuel gauge indicates that the red and yellow lights are on, it should be charged; if only the red light is on, stop running and charge as soon as possible, otherwise the battery will be over-discharged and its life will be seriously shortened. After fully charged, the running time is short, and the charging time should not be too long, otherwise it will cause overcharging and cause the battery to heat up. Overcharging, overdischarging and undercharging will shorten battery life.

　　There are also charging points on the highway

　　According to the plan, by 2020, the State Grid Corporation of China will build a total of 10,000 public fast charging stations and 120,000 charging piles across the country, covering all cities in the Yangtze River Delta and expressway fast charging in major cities in other regions. The network covers a total of 202 cities and 36,000 kilometers of expressways. By 2017, a public urban charging network with a radius of five kilometers will be basically completed in Beijing.

　　Expressway special card: The charging piles of the State Grid need to use the "highway special charging card" on the expressway, and the charging card in ordinary cities cannot be used. With a special charging card for highways, you can basically charge on the go. Handling method: Vehicle owners can apply for a "Special Expressway Charging Card" at a designated business hall.

　　If you don’t have time to go to the outlet’s business hall in person, you can also call 95598 customer service at least 45 minutes in advance and up to 3 days in advance to make an appointment for charging at the designated charging service area. The staff of the highway charging pile will arrive within 45 minutes and guide the car owner on site. Charge.
