The invention discloses a light logistics vehicle thermal management system which comprises a power battery water cooling plate, a driving motor, an electric control system, an electric driving radiator, a condenser, an electric compressor and an evaporator. The power battery water cooling plate is communicated with a battery radiator and a battery cooler, and a second electric control three-way valve is arranged between the power battery water cooling plate and the battery radiator; and a first electric control three-way valve is communicated with a pipeline between the power battery water cooling plate and the battery cooler and is communicated with the electric drive radiator. According to the heat management system for the light logistics vehicle, on the basis of an existing water-cooling electric driving system and an existing liquid-cooling battery system, two sets of liquid-cooling systems are connected through combined control of two electric control three-way valves, and it can be guaranteed that the two systems work independently according to the heat dissipation requirements of different working conditions; and the circulation paths of the two systems can be changed to achieve the purposes of rapid temperature rise, effective temperature reduction, redundancy reduction, energy conservation and cost reduction.
