Embodiment 1
[0063] According to one aspect of the present invention, a method for identifying the type of charging pile is provided, such as figure 1 As shown in the flowchart of the method, the method includes:
[0064] Step S101, within the first preset time period after the electric vehicle is connected to the charging pile, determine whether a handshake message sent by the charging pile is received;
[0065] Step S102, if the judgment result is yes, it is determined that the charging pile is the first type of charging pile, and charging is performed according to the charging standard procedure corresponding to the first type of charging pile;
[0066] Step S103, if the judgment result is negative, it is judged that the reception of the handshake message has timed out, and in the charging parameter configuration process, it is judged that the charging pile is the first type according to whether there is minimum charging current information in the maximum output capability message sent ...
Embodiment 2
[0095] According to another aspect of the present invention, a device for identifying the type of charging pile is also provided, such as Figure 7 As shown, the device includes:
[0096] The first judging module 701 is used to judge whether the handshake message sent by the charging pile is received within the first preset time period after the electric vehicle is connected to the charging pile;
[0097] The judging module 702 is configured to judge that the charging pile is a charging pile of the first type when the judgment result of the first judging module 701 is yes, and charge according to the charging standard procedure corresponding to the charging pile of the first type;
[0098] The second judging module 703 is used to determine whether the received handshake message has timed out when the judging result of the first judging module 701 is no, and in the charging parameter configuration process, according to whether there is The minimum charging current information ...

Abstract
The invention provides a charging pile type identification method and device. The method comprises the steps that whether a handshake message transmitted by a charging pile is received is judged in a first preset time period after an electric automobile is connected with the charging pile; the charging pile is judged to be the first type of charging pile if the judgment result is yes, and charging is performed according to the charging standard procedure corresponding to the first type of charging pile; the received handshake message is judged to be time-out if the judgment result is no, the charging pile is judged to be the first type or second type of charging pile according to existence of minimum charging current information in the maximum output capacity message transmitted by the charging pile in the charging parameter configuration process, and charging is performed according to the charging standard procedure corresponding to the type of charging pile. Therefore, the type of the charging pile can be identified through judgment of transmitting of the handshake message of the charging pile and existence of the minimum charging current information in the transmitted maximum output capacity message so that the success rate of charging can be guaranteed and the user experience can be enhanced.
Description
technical field [0001] The invention relates to the technical field of electric vehicle control, in particular to a method and device for identifying the type of a charging pile. Background technique [0002] At present, electric vehicle charging is an important part of electric vehicle control. After the implementation of the new charging national standard in 2016, there will be two states of DC fast charging piles on the market-the charging piles of the old national standard and the charging piles of the new national standard. Although the new national standard will take into account the charging compatibility of the old charging piles on the market when formulating the charging standard, the status of the old charging piles is mixed. If it is really implemented according to the new national standard, there will be many problems when the vehicle is charging and it will not be able to charge. [0003] Specifically, GB27930-2015 new national standard fast charging standard c...
