Embodiment Construction
[0046] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0047] like figure 2 Shown is a working flow chart of an electronic control unit charging fault processing method for an electric vehicle of the present invention, including:
[0048] Step S201, in response to a charging fault, stop charging, and determine whether the charging fault is a recoverable fault;
[0049] Step S202, if the charging fault is a recoverable fault, send sleep information to other electronic control units of the electric vehicle except the electronic control unit, and enter a pseudo sleep state. After receiving the sleep information, the other electronic control units Entering sleep, in the pseudo sleep state, the electronic control unit does not enter sleep, detects whether the charging fault has recovered, and if it is detected that the charging fault has recovered, wakes up other electronic control units and r...

The invention discloses a charging fault processing method for an electronic control unit of an electric vehicle and the electronic control unit, and the method comprises the steps: responding to a charging fault, stopping charging, and determining whether the charging fault is a recoverable fault; if the charging fault is a recoverable fault, dormancy information is sent to other electronic control units except the electronic control unit of the electric vehicle, the electronic control units enter a pseudo dormancy state, the other electronic control units enter dormancy after receiving the dormancy information, in the pseudo dormancy state, the electronic control unit does not enter dormancy, and in the pseudo dormancy state, the electronic control unit does not enter dormancy; and detecting whether the charging fault is recovered, if the charging fault is detected to be recovered, awakening other electronic control units, and recovering charging. When a recoverable charging fault occurs in vehicle charging, the electronic controller serving as a fault recovery detection controller does not sleep, other ECUs of the vehicle enter sleep, it can be guaranteed that the quiescent current of the whole vehicle is small, feeding of a small storage battery is not caused, and charging can be continued after a charging fault source is recovered.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method for handling charging faults of an electronic control unit of an electric vehicle and an electronic device. Background technique [0002] There are more and more new energy vehicles on the market. New energy vehicles, or electric vehicles, have a more urgent need for high battery life and fast charging. Therefore, DC charging scenarios are becoming more and more extensive, especially the fast charging technology of high-energy battery packs is more urgent. However, the DC charging technology is not yet perfect, and the failure of DC charging is not uncommon, but many faults can be recovered after a period of time, such as: the grid voltage is too high, the grid voltage is too low, the charging equipment is overheated (especially in the outdoor high temperature environment), Wait. [0003] Generally, the DC charging system is mainly controlled by a battery ma...
