The invention provides a battery thermal management method and system, vehicle-mounted terminal equipment and a vehicle. The battery thermal management method comprises the steps of determining heating heat of a target element in a target vehicle according to a travel distance between the target vehicle and a target charging pile; according to the current temperature of the battery in the target vehicle and the target temperature, the required heat of the battery is calculated; wherein the target temperature comprises the charging temperature of the battery; performing thermal management control on the battery based on the required heat of the battery, specifically, performing thermal management control on the battery: when the required heat is a positive value and is greater than the heating heat, preheating the battery; or when the required heat is a negative value, the battery is cooled. Therefore, the battery is subjected to thermal management, the target vehicle can be directly charged after being connected with the charging gun, and the battery does not need to be preheated or cooled, so that the charging efficiency is improved, the energy consumption is reduced, and the charging waiting time and the economic cost of a user can be saved.

    本申请提供一种电池热管理方法及系统、车载终端设备及车辆,包括:根据目标车辆与目标充电桩的行程距离确定目标车辆中目标元件的发热热量;以及,根据目标车辆中电池的当前温度以及目标温度,计算电池的需求热量;其中,目标温度包括电池的充电温度;基于电池的需求热量对电池进行热管理控制,具体地,对电池进行热管理控制包括:在需求热量为正值且大于发热热量时,对电池进行预热;或者,在需求热量为负值时,对电池进行散热。所以,本申请通过对电池进行热管理,当目标车辆与充电枪连接后能够直接充电,不需要再对电池进行预热或散热,从而提高了充电效率,降低能源消耗的同时还能节省用户充电等待时间和经济成本。
