Abstract
(EN) A heating control method, comprising: when a vehicle is in a high-voltage power-on state, acquiring a battery temperature, an ambient temperature, and a state-of-charge value of a battery; if the battery temperature is less than a battery temperature threshold, the ambient temperature is less than an ambient temperature threshold, and the state-of-charge value of the battery is greater than a state-of-charge value threshold, heating the battery; and determining a target cut-off temperature according to historical data of the vehicle, and stopping heating the battery after the battery is heated to the target cut-off temperature. Also disclosed are a heating control apparatus applying the heating control method, a computer device, and a storage medium. Raising the temperature of a power battery by means of a battery heating function to keep the power battery out of an excessively low temperature and restore its maximum power capability for discharging and charging, and recovering braking energy as much as possible on the premise of meeting the winter power performance of the vehicle facilitate prolonging the winter driving mileage of battery electric vehicles.
(FR) L'invention concerne un procédé de régulation de chauffage, comprenant les étapes consistant à : lorsqu'un véhicule est en état d'activation sous haute tension, acquérir une température de batterie, une température ambiante et une valeur d'état de charge d'une batterie ; si la température de batterie est inférieure à un seuil de température de batterie, la température ambiante est inférieure à un seuil de température ambiante et la valeur d'état de charge de la batterie excède un seuil de valeur d'état de charge, chauffer la batterie ; et déterminer une température cible de coupure selon des données historiques du véhicule et arrêter le chauffage de la batterie après chauffage de la batterie jusqu'à la température cible de coupure. Sont divulgués également un appareil de régulation de chauffage appliquant le procédé de régulation de chauffage, un dispositif informatique et un support de stockage. L'élévation de la température d'une batterie de puissance au moyen d'une fonction de chauffage de batterie pour maintenir la batterie de puissance à l'abri d'une température excessivement basse et pour restaurer sa capacité optimale de puissance pour la décharge et pour la charge, ainsi que la récupération maximale d'énergie de freinage, sur la base de la vérification des performances hivernales de puissance du véhicule, facilitent l'extension du kilométrage de conduite hivernale de véhicules électriques à batteries.
(ZH) 一种加热控制方法,包括:在车辆处于高压上电状态的情况下,获取电池温度、环境温度和电池荷电状态值;在所述电池温度小于电池温度阈值、所述环境温度小于环境温度阈值且电池荷电状态值大于荷电状态值阈值的情况下,对电池进行加热;根据车辆的历史数据确定目标截止温度,当电池被加热至所述目标截止温度后,停止对电池进行加热。还公开了一种应用加热控制方法的加热控制装置、计算机设备及存储介质。通过电池加热功能将动力电池的温度升高,使其脱离过低的温度,恢复其放电和充电的最大功率能力,同时在满足车辆的冬季动力性的前提下能尽可能多的回收制动能量,有利于延长纯电动汽车的冬季续驶里程。
