The invention discloses a hybrid vehicle heat storage type heat pump system and a vehicle, and belongs to the technical field of vehicles. The system comprises: a heat pump unit; an auxiliary heating circuit; an engine cooling water waste heat recovery circuit; a first heat storage loop and a battery heating loop. The auxiliary heating loop can further meet the large heating requirement of the passenger compartment, engine cooling water waste heat recovery enables heat of engine cooling water to be better utilized, and meanwhile energy consumption of the heating loop is reduced. The first heat storage loop and the first heat utilization loop store and reuse heat of engine cooling water, and the effect of efficiently utilizing the heat of the engine cooling water is achieved. And the battery heating loop can heat the power battery by using a PTC heater, so that the endurance attenuation of the power battery is reduced, and the endurance mileage of the power battery under a low-temperature background is guaranteed. The power battery can be directly or indirectly heated by the first heat storage body and/or the engine cooling water, so that the waste heat energy of the engine cooling water is fully utilized, and the utilization effect of the waste heat energy is improved.
