Embodiment Construction
[0062]Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0063] figure 1 It is a flowchart of a battery warning method provided by an exemplary embodiment of the present disclosure; see figure 1 , a battery warning method applied to an electric vehicle, the method comprising:
[0064] Step 101, acquiring the current remaining power of the battery and the temperature of the environment.
[0065] For example, the remaining capacity SOC is the percentage of the remaining capacity of the battery, indicating the ratio of the remaining capacity of the battery after it has been used for a period of time or left unused for a long time to the capacity of the fully charged state, usually expressed as a percentage from 0% to...

The disclosure relates to a battery early warning method and device and a vehicle. The method comprises the steps: acquiring the current remaining capacity of a battery and the temperature of an environment where the battery is located; determining the discharge power of the battery according to the current remaining capacity of the battery and the temperature of the environment; acquiring the power demand of an electric vehicle under the current condition; determining whether a secondary early warning condition is met or not according to the discharge power of the battery and the current power demand of the electric vehicle;if so, carrying out warning prompting according to a preset mode; and if not, not carrying out warning prompting. According to the invention, accurate early warning prompt can be carried out according to the available electric quantity of the battery under different temperatures and different residual electric quantity percentages, adaptive early warning prompt canalso be carried out according to specific battery use working conditions, and the accuracy and the adaptability of a battery early warning strategy can be effectively improved.
Description
technical field [0001] The present disclosure relates to the technical field of batteries, and in particular, to a battery early warning method, device and vehicle. Background technique [0002] Because electric vehicles have the characteristics of saving fuel energy, zero emissions, low noise and high efficiency, they are gradually favored by the majority of vehicle users. However, the shortcomings of electric vehicles such as short driving range and long charging time limit the use of electric vehicles. market share. At present, electric vehicles are usually only equipped with a low-SOC (State of Charge) early-warning function in terms of battery low-battery warning strategies, that is, when the current SOC of the battery is low, an alarm is issued (usually when the remaining power percentage of the battery is at 10%-20% alarm), to prompt the driver to charge. However, when the vehicle is at different temperatures, the discharge capacity and discharge power of the batter...
