New energy vehicle energy flow test service
The new energy vehicle energy flow test bench can analyze the distribution of the power provided by the power battery to the various components such as the effective power, heat loss, and mechanical friction loss under different operating conditions in the test room, and analyze the electric power from the perspective of system integration. The process of energy conversion and transfer in the powertrain of an automobile optimizes the matching of the components of an electric vehicle powertrain, improves the operating efficiency of each component, and provides guidance for the design of the powertrain and its thermal management system. The system establishes a battery loss model, an electronically controlled loss model, a motor loss, a transmission loss, and a transmission shaft loss model. The related parameters that affect the battery, electronic control, motor, transmission, and transmission shaft can be optimized and analyzed.
The system consists of a large base plate, loading motor, torque sensor, drive shaft, motor base, inverter cabinet, control system, voltage, current, temperature, pressure, speed, torque and other data acquisition systems, power analyzers, simulation software, charging piles, etc. composition.
Power test range: ≤300KW
Torque test range: <7400Nm
Speed test range: ≤3300rpm
