Embodiment Construction

[0027] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0028] The invention provides a charging control system and control method for a plug-in hybrid electric bus. After inserting the charging gun, the 24V low-voltage power supply of the national standard charging gun is used to automatically activate the combination meter, the vehicle controller VMS and the remote monitoring terminal, the combination meter, The body control module and the vehicle controller automatically switch to the charging control mode, shielding the engine start signal, gear signal and accelerator signal to prevent the vehicle from being started by mistake during charging.

[0029] Such as Figure 1(a)-Figure 1(b) As shown, a ...

Abstract

The invention discloses a charge control system of a plug-in hybrid power bus. A remote monitoring terminal, a whole bus controller VMS and a combination instrument can be awakened by a charging-awakening power supply, and the combination instrument can awaken a bus body control module. The whole bus controller VMS controls powering on and off of a battery management system (BMS) through a BMS power supply relay. The BMS controls switching on and off of a charging contactor. The whole bus controller VMS is further connected with a charging cabin door sensor. After a charging gun is plugged, a 24V low-voltage power supply of an international charging gun is utilized to automatically activate the combination instrument, the whole bus controller VMS and the remote monitoring terminal without manual power supply switching for activation, and charging operation steps are simple. After the charging gun is inserted, the combination instrument, the bus body control module and a whole bus controller are automatically switched to be in a charging control mode, an engine starting signal, a gear signal and an accelerator signal are shielded, mistaken bus startup is prevented during charging, and safety and reliability are high.

Description

technical field [0001] The invention relates to the charging control field of a plug-in hybrid electric passenger car, in particular to a charging control system and a control method of a plug-in hybrid electric passenger car. Background technique [0002] Plug-in hybrid buses have become the main force in the development of new energy buses due to their pure electric drive mode, unlimited driving range and reasonable cost. At present, when charging, it is necessary to manually turn on the vehicle power supply or the charging switch to activate the work of each controller required for charging, and the charging steps are cumbersome. At the same time, there is no uniform standard for the charging control method of plug-in hybrid electric buses in the country, and the charging control strategies of different manufacturers are different. When the charging gun is inserted, if the charging circuit design is not reasonable and the control strategy is not thoughtful, it is easy to ...
