To provide a battery pack heating system and a control method therefor that improve heating efficiency of a battery pack.SOLUTION: A battery pack heating system is provided in which: a battery management module obtains state parameters of a battery pack, and sends a low-temperature low-electric-quantity heating request command to each of a vehicle overall controller and an auxiliary charging branch circuit control module if a state parameters satisfy a preset low-temperature low-electric-quantity condition; an auxiliary charging branch control module sends a first control signal to control an auxiliary charging branch circuit to be turned on; and the vehicle overall controller sends a second control signal, so that a motor controller controls on-off of switch modules in an inverter and sends a third control signal so that a battery management module controls on-off of a main positive switch, so that the battery pack and a motor transmit energy to each other to heat the battery pack.SELECTED DRAWING: Figure 1

    【課題】電池パックに対する加熱効率を向上させる電池パック加熱システム及びその制御方法を提供する。【解決手段】電池パック加熱システムにおいて、電池管理モジュールは、電池パックの状態パラメータを取得し、且つ、状態パラメータが予め設定された低温低電力条件を満たす場合、車両全体コントローラ及び補助充電分岐回路制御モジュールにそれぞれ低温低電力加熱要求コマンドを送信する。補助充電分岐回路制御モジュールは、第1の制御信号を送信し、補助充電分岐回路が導通されるように制御する。車両全体コントローラは、第2の制御信号を送信し、モータコントローラにインバータにおけるスイッチモジュールのオン・オフを制御させ、且つ第3の制御信号を送信し、電池管理モジュールにメイン正極スイッチのオン・オフを制御させることで、電池パックとモータとの間で相互にエネルギーを伝達させて、電池パックを加熱する。【選択図】図1
