Embodiment 1

[0056] Such as figure 1 Shown is a schematic flow chart of a new energy vehicle battery replacement design method based on a remote monitoring terminal provided by an embodiment of the present invention. figure 1 The method shown includes the following steps:

[0057] S1: Establish a Bluetooth connection with the power station by broadcasting the VIN of the vehicle through the remote monitoring terminal Bluetooth;

[0058] In this example, if figure 2 As shown, step S1 includes:

[0059] S1.1: When the vehicle is ON, the remote monitoring terminal Bluetooth broadcasts the VIN of the vehicle at a preset frequency;

[0060] Among them, the size of the preset frequency can be determined according to specific conditions, such as figure 2 The 100ms in this embodiment is not uniquely limited.

[0061] S1.2: Receive the Bluetooth connection request sent by the battery swapping station, perform authentication and authentication through the key, and realize the Bluetooth connect...

Embodiment 2

[0101] Such as Figure 9 Shown is a schematic structural diagram of a remote monitoring terminal for new energy vehicle battery replacement design provided by an embodiment of the present invention, including:

[0102] The Bluetooth connection module 201 is used to establish a Bluetooth connection with the power station by broadcasting the VIN of the vehicle through the remote monitoring terminal Bluetooth;

[0103] The battery replacement preparation module 202 is used to receive the process status of the battery replacement station sent by the battery replacement station to the vehicle after the vehicle Bluetooth authentication, and to indicate that the vehicle has parked in the slot, and to judge the battery replacement preparation;

[0104] The self-diagnostic module 203 is used to determine that the vehicle meets the preparation conditions for battery replacement, and receives the high-voltage and low-voltage instructions sent by the battery replacement station, and start...

Abstract

The invention discloses a vehicle battery replacement design method based on a remote monitoring terminal and the remote monitoring terminal, and belongs to the technical field of vehicle battery replacement. The method comprises the following steps that: a Bluetooth connection is established with a battery swap station in a manner of broadcasting a VIN of a vehicle by a remote monitoring terminal through Bluetooth; after the vehicle is subjected to Bluetooth authentication, a battery replacement station process state sent by a battery replacement station to the vehicle is received and used for indicating that the vehicle is parked in the slot, and battery replacement preparation judgment is carried out; after it is judged that the vehicle meets the battery replacement preparation condition, a high-voltage lowering instruction and a low-voltage lowering instruction sent by a battery replacement station are received, and automatic vehicle power-off operation is started; and after low voltage lowering is completed, a low voltage lowering completion instruction is sent to the battery swap station, the battery swap station starts automatic battery swap, meanwhile, the remote monitoring terminal obtains the vehicle state and the battery swap result, and corresponding processing is conducted according to the vehicle state and the battery swap result. According to the invention, the reliability in the battery replacement process can be improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle battery replacement, and more specifically relates to a design method for battery replacement of new energy vehicles based on a remote monitoring terminal and a remote monitoring terminal. Background technique [0002] In order to realize that during the process of replacing the battery pack of the new energy vehicle, the swap station can automatically complete the acquisition and replacement of the battery pack information of the new energy vehicle, it is necessary to realize the vehicle information interaction with the swap station through the vehicle communication terminal on the vehicle side. At present, the control method of automatically replacing the power battery pack of the vehicle is as follows: the vehicle communicates with the swap station, and the swap station obtains the vehicle status. When the battery swap conditions are met, the swap station automatically replaces the battery pack....
