Abstract

The invention discloses a vehicular communication terminal, comprising a battery, a power management unit, a microcontroller unit, a switching unit to switch batter supply or external power supply, and a normally live wire detection unit to detect voltage of a normally live wire, wherein the power management unit converts power output by the battery, the microcontroller unit compares the voltage of the normally live wire to a preset voltage and controls a changeover unit to perform switching when the voltage of the normally live wire is less than the preset voltage, and the battery is allowedto power the vehicular communication terminal. The vehicular communication terminal according to the technical scheme can gain long-term standby.

Description

technical field [0001] The invention relates to the technical field of vehicle communication, in particular to a vehicle communication terminal. Background technique [0002] While the state's support for new energy vehicles has increased, supervision has also increased, requiring new energy vehicles to have a communication terminal to collect and save key state parameters of the vehicle and system components and send them to the platform. [0003] The vehicle-mounted communication terminals currently on the market are generally composed of a GPS module, a communication module, a microcontroller and related interfaces. The application direction of each manufacturer is different, and their respective architecture combinations are not the same. Some may not have a GPS module, and some may not be connected to the vehicle bus system. [0004] However, none of the technical solutions here has a back battery, and it is impossible to realize the long-term standby of the vehicle co...
