Embodiment Construction

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0032] Before describing the vehicle, the high-voltage control system and the control method thereof according to the embodiments of the present invention, the importance of battery charging safety will be briefly described below.

[0033] Such as figure 1 As shown, there is only one charging contactor in the charging circuit, that is, the charging contactor 10. When the charging contactor 10 is stuck, the charger 20 will not be able to complete the task of disconnecting the charging circuit after charging the battery pack 30. I...

Abstract

The invention discloses a high-voltage control system of a vehicle and a control method of the high-voltage control system. The high-voltage control system comprises a power battery, a charging control device, a detecting module, and a charging protective circuit, wherein the charging control device is used for controlling the switching on and switching off of a charging loop, and comprises a control switch and a controller; the control switch is arranged in the charging loop; the detecting module is used for detecting whether the control switch is stuck or not; the charging protective circuit comprises a charging protective switch and a charging protective controller, so that when the situation that the control switch is stuck is detected by the detecting module, the charging circuit is switched off by the charging protective controller through the charging protective switch. According to the high-voltage control system disclosed by the invention, when the control switch is stuck, the charging circuit is switched off by the charging protective switch, so that the charging safety of a battery is well guaranteed, and the safety and the reliability of the vehicle are improved. The invention further discloses a vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle, a high-voltage control system and a control method thereof. Background technique [0002] At present, incidents of vehicle fires occur from time to time, especially for new energy vehicles, whose fires caused by battery overcharging account for about 80%, so the safety issue of battery charging needs to be solved urgently. [0003] In the related art, the components on the charging circuit of the vehicle are all installed in the battery control cabinet, and there is only one charging contactor in the charging circuit, and the closing and opening of the charging contactor are controlled by BMS (BATTERY MANAGEMENT SYSTEM, battery management system) control. Therefore, if the charging contactor or BMS fails, the battery charging safety cannot be guaranteed. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the rel...
