[0004] At present, the way to upgrade the application program of the BMS (Battery Management System) of electric vehicles requires after-sales personnel to go to the site to complete the upgrade process, so the labor time cost is high, the user cannot know the detailed information of the upgraded version, and it cannot realize intelligence
In addition, in the above-mentioned BMS remote upgrade method, the program update information is directly pushed to the vehicle-mounted GPS module, which is prone to cause the vehicle to upgrade the BMS while driving due to system judgment errors, so there is a greater potential safety hazard

Embodiment Construction
[0030] In order to make the object, technical solution and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.
[0031] like figure 1 As shown, an electric vehicle BMS upgrade system 300 provided by the present invention includes an electric vehicle 100 and a charging pile 200 .
[0032] The electric vehicle 100 includes a charging pack 110 , an auxiliary power source 120 , a BMS 130 and a charging stand 140 . Wherein, the BMS 130 includes a selection module 131 , a collection module 132 and a main control module 133 . The selection module 131 is used to receive an external selection signal and select a corresponding working mode. In this embodiment, the wo...

An electric vehicle BMS updating method comprises the following steps that a battery charging gun is inserted into a battery charging base; an external selection signal is received; an updating mode is selected; a main control module determines that the battery charging gun is successfully connected, and then a battery pack is closed, so the main control module is disconnected; whether the BMS and an insulation state of a battery charging pile are normal is determined; an auxiliary power supply is started for charging and the main control module is opened if the BMS and an insulation state of a battery charging pile are normal; update handshake is conducted to the main control module and an updating module; the update control module determines whether BMS meets an updating condition, and conducts charging and discharging lock to a finished automobile if the BMS meets the update condition; the update module sends BMS version updating information to the main control module and then starts to update BMS; whether updating is finished is determined; and updating of the BMS is stopped if the updating is finished. By the use of the electric vehicle BMS updating system and the method, potential safety danger caused by BMS update during the driving of the vehicle due to misjudgments of the system can be avoided.
Description
[0001] 【Technical field】 [0002] The invention relates to the technical field of electric vehicles, in particular to a BMS upgrade system and method for electric vehicles. [0003] 【Background technique】 [0004] At present, the way to upgrade the application program of the BMS (Battery Management System) of electric vehicles requires after-sales personnel to go to the site to complete the upgrade process, so the cost of labor time is high, and the user cannot know the detailed information of the upgraded version, and it cannot realize intelligence. In addition, in the above-mentioned BMS remote upgrade method, the program update information is directly pushed to the vehicle-mounted GPS module, which is prone to cause the vehicle to upgrade the BMS while driving due to system judgment errors, so there is a greater potential safety hazard. [0005] In view of this, it is necessary to provide a system and method for upgrading the BMS of electric vehicles to overcome the above-me...
