Embodiment Construction

[0012] An electric vehicle intelligent navigation system, including a navigation unit, a calculation unit, and a display unit. The navigation system transmits information to the calculation unit for calculation and then displays it on the display unit. It also includes a battery detection unit. The battery detection unit detects the battery remaining The battery detection unit sends the detection result to the calculation unit, and the display unit displays the calculation result. Wherein, the navigation unit is networked with the global positioning system, and while obtaining the latest map, it can also receive real-time road condition information, and obtain the best route after calculation by the calculation unit.

[0013] The calculation unit can predict the short-term load of the battery according to the detection result of the battery detection unit, and display it on the display unit. At the same time, the calculation unit can also calculate the remaining mileage at an ...

Abstract

The invention provides an intelligent navigation system of an electric automobile. The intelligent navigation system comprises a navigation unit, a calculation unit and a display unit, wherein the navigation system transmits information to the calculation unit for calculating and then to the display unit for displaying, the intelligent navigation system further comprises a battery detection unit which is used for detecting the residual capacity of the battery and transmitting the detection result to the calculation unit, and the display unit is used for displaying the calculation result. According to the intelligent navigation system of electric automobile, disclosed by the invention, a driver can master the remaining capacity of the electric automobile, and can accurately master the situation of a charging station by networking with an information network and a power grid, so that the driver can reasonably select the charging stations.

Description

technical field [0001] The invention relates to a navigation system, in particular to an electric vehicle intelligent navigation system. Background technique [0002] With the introduction of China's new energy vehicle subsidy policy, electric vehicles have officially moved from the pilot stage to the listing stage in China. As we all know, electric vehicles are powered by charging. At present, the internationally accepted SAEJ1772-2010 standard stipulates three charging methods: AC Level1 for slow charging and AC Level2 and DC charging for fast charging. Among them, slow charging is mainly completed by charging piles, and the charging time is more than 6 hours, which is suitable for electric vehicles that are parked for a long time. The fast charging is mainly completed in the charging station, and the charging time is 15 minutes to 2 hours. It is suitable for emergency charging of electric vehicles and daily charging of buses and taxis, and the charging power at this ...
