The invention provides an electric automobile waste heat recovery heat pump type comprehensive heat management system automatically adjusted in filling amount. The work of the electric automobile waste heat recovery heat pump type comprehensive heat management system comprises heat management of a heat pump type automobile inside environment, waste heat recovery and heat management of a driving motor system, waste heat recovery and heat management of a power battery system, automatic adjustment of the working medium filling amounts in different operating modes and the like, comprehensive integrated heat management of the three mentioned portions is achieved, above 50% of electric energy can be saved compared with an existing electric-heating heating system, and accordingly driving mileage of one-time battery charging of an electric automobile can be increased by above 30%. Waste heat of a driving motor of the electric automobile and waste heat of the power battery system are recovered, automatic adjustment of the working medium filling amount is achieved, further the energy efficiency of the system is improved, the load of an automotive outside heat exchanger during heating is reduced, and the heat safety of the driving motor system and the power battery system is ensured. In addition, heat damage to the system can be avoided, the reliability of the system can be improved, and the service life of the system can be prolonged.
