Problems solved by technology

[0005] However, in the prior art, for the parked pure electric vehicles, the data of the battery system cannot be monitored generally.
There are two main reasons: the first is that the vehicle-mounted terminal does not support the function of regularly waking up

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] An embodiment of the present invention provides a method for monitoring battery data when a pure electric vehicle is parked, including the following steps: a remote monitoring vehicle-mounted terminal (hereinafter referred to as the vehicle-mounted terminal) is connected to the normal power of the vehicle; signal line, to judge that the vehicle is in the parking state (the ignition signal and the charging signal are both low); the vehicle terminal enters the timing sleep state after sending the cached data to the platform; the timing sleep time can generally be set to 1 hour, when After the sleep time is up, the vehicle-mounted terminal itself enters the working state, and then outputs a 12V level control signal to wake up the BMS, so that the BMS and other related controllers enter the working state; after the battery managemen...

Abstract

The invention discloses a method for monitoring battery data under a parking state of a pure electric vehicle and a vehicle-mounted terminal. The method comprises the steps that the fact that the vehicle is under the parking state is determined; a first timer is started; after the first timer reaches the first preset duration, an awaking signal is output to a battery management system in the vehicle; the battery data reported by the battery management system are received; the battery data are sent to a control platform; a dormancy signal is output to the battery management system to enable the battery management system to enter a dormancy or closed state. The method for monitoring the battery data under the parking state of the pure electric vehicle and the vehicle-mounted terminal can monitor the battery data under the parking state of the pure electric vehicle, and not only can collect accurate battery voltage and temperature data, but also do not consume a large amount of energy capacity of a battery in the whole working process.

Description

technical field [0001] The invention relates to a method for monitoring battery data in a parked state of a pure electric vehicle, which can solve the problem that the battery data cannot be monitored in the parked state, and provide a safety warning function to avoid major accidents such as spontaneous combustion in the parked state of the vehicle. Background technique [0002] According to national regulations, pure electric vehicles need to be installed with vehicle remote monitoring vehicle terminals. The vehicle-mounted terminal communicates with the vehicle battery management system (BMS), the vehicle controller and other controllers through the CAN bus, obtains the data and fault information of each control system in real time, and then sends them to the remote monitoring platform (generally by the government or the vehicle The monitoring platform will process and judge the safety warning after receiving the vehicle data. If the battery voltage or temperature is found...
