Lamp circuit capable of indicating charging capacity

Abstract

The invention relates to the technical field of automobile lamps, more specifically to a lamp circuit capable of indicating charging capacity. The lamp circuit capable of indicating the charging capacity specifically comprises a single chip microcomputer power supply circuit module, a signal receiving and transmitting conversion circuit module, a position lamp constant current circuit module and asingle chip microcomputer detection control circuit module, wherein the single chip microcomputer power supply circuit module provides linear voltage stabilizing power supply; the signal receiving and transmitting conversion circuit module performs conversion and communication on data between an automobile body controller and the single chip microcomputer detection control circuit module; and thesingle chip microcomputer detection control circuit module is connected with the module, receives an automobile body controller signal transmitted by the signal receiving and transmitting conversioncircuit module and drives LED lamps in both the position lamp constant current circuit module and an identification lamp constant current circuit module to be turned on according to designated brightness and effects. According to the lamp circuit capable of indicating the charging capacity, a position lamp and a LOGO lamp adjust the brightness and dynamical turn-on effect of LED in real time according to a battery capacity signal to show the interval of battery capacity; a user can observe the charging capacity from the outside of the automobile without entering into an automobile to start theautomobile; and therefore, the lamp circuit capable of indicating the charging capacity is convenient, fast and visual.

Description

technical field [0001] The invention relates to the technical field of automobile lamps, and more specifically relates to a lamp circuit for indicating charging power. Background technique [0002] With the development of the economy, my country's car ownership and car market have leapt to the first place in the world. With the public's increasing concern on environmental pollution, the gradual depletion of traditional energy sources and the exhaust pollution caused by fuel vehicles, electric vehicles have become the main development direction of automobiles. my country has put forward an important long-term strategy for the development of new energy vehicles, and encourages enterprises to develop and produce new energy vehicles. [0003] During the use of new energy vehicles, it is inevitable to need to be charged, so the body should have lights that can correctly indicate the battery power during charging. At present, the multi-purpose meter of electric vehicles on the m...
