The invention discloses a battery thermal management method and system and a hybrid vehicle. A first volume of combustion waste gas and a second volume of combustion waste gas are shunted through a first exhaust valve and a second exhaust valve of an engine, and an automobile electronic control unit controls the on or off state of a first output end and a second output end of a switch unit according to the detected real-time temperature of a battery. Therefore, the heat of the combustion waste gas of the first volume is used for heating the battery, waste of waste gas heat is reduced, the waste gas energy utilization rate is increased, the battery energy consumption is reduced, and the endurance performance is improved.
