Embodiment Construction

[0073] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0074] In the solution provided by the invention, by pre-judging the intention of the vehicle to go to the charging station, the charging demand of the vehicle is actively identified, and then before the vehicle arrives at the charging station, if the charging conditions under low temperature conditions are met, the user will be charged through human-computer interaction. The system authorizes the battery to be preheated through the thermal management system to ensu...

Abstract

The invention discloses a vehicle in-transit battery preheating method and system and a vehicle. The method comprises the steps: acquiring vehicle navigation information and battery information; afterit is determined that the vehicle goes to a charging station according to the navigation information, determining whether the vehicle meets a preset battery preheating starting condition or not based on the battery information; when the preset battery preheating starting condition is met, sending a battery preheating request to a human-machine interaction system of the vehicle; and sending a battery preheating instruction to a thermal management system according to the obtained first user authorization starting information generated by the human-machine interaction system in response to thebattery preheating request so as to heat the battery. The charging rate of the battery in a low-temperature environment can be effectively improved, and the low-temperature vehicle use experience of auser is enhanced.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a vehicle battery preheating system and a vehicle. Background technique [0002] New energy vehicles are the current development trend of the automotive industry. Since the lithium batteries used in electric vehicles have serious low-temperature restrictions, the activity of the positive and negative electrode materials of the battery and the conductivity of the electrolyte will decrease when the temperature is lower than 0°C, resulting in a decrease in the performance of the lithium battery. decrease, the battery capacity decreases. Therefore, the chemical characteristics of the battery pack itself lead to a very slow charging speed of electric vehicles in low-temperature environments in winter. Users wait for a long time for charging in cold environments, causing serious charging anxiety and poor charging experience. Contents of the invention [0003] The invention provide...
