The invention discloses an electric vehicle thermal management system and an electric vehicle. The system comprises a battery module, an electric drive module, a heat pump module, a first heat exchanger and a second heat exchanger. The heat pump module comprises a first refrigerant channel. The battery module comprises a battery pack and a first cooling liquid channel; cooling liquid in the first cooling liquid channel exchanges heat with refrigerant in the first refrigerant channel through the first heat exchanger. The electric driving module comprises an electric driving unit and a second cooling liquid channel; the air conditioner further comprises a second refrigerant channel, and cooling liquid in the second cooling liquid channel exchanges heat with refrigerant in the second refrigerant channel through a second heat exchanger. The second refrigerant channel is connected with part of the first refrigerant channel in parallel, and the second refrigerant channel is connected with the first refrigerant circulation area of the first heat exchanger in series. By means of the scheme, the heat dissipation requirement of the electric drive system can be met, the energy consumption of the heat management system can be reduced, the energy efficiency ratio of the system is increased, and the cruising ability of a power battery is improved.
