Meanwhile, a chemical heat storage technology is adopted in the heat storage module, heat energy can be stored for a long time with almost no heat loss, and the stored heat can be used for passenger compartment heating when the vehicle is started and the cold start heating of a fuel cell and a power cell ina low-temperature environment. The working performance and reliability of the core part of the fuel cell vehicle can be remarkably improved, and the service life is remarkably prolonged.

Description

technical field [0001] The invention belongs to the technical field of fuel cell vehicles, and relates to a cooperative management system suitable for the thermal system of fuel cell vehicles, in particular to a cooperative management system for the thermal system of fuel cell vehicles with heat storage function. Background technique [0002] The contradiction between the society's ever-growing energy demand and the shortage of fossil fuels and serious environmental pollution is becoming increasingly severe. The world is in the midst of a "clean, low-carbon, safe, and efficient" energy revolution. The general trend of energy conservation and emission reduction has given birth to sustainable development of the hydrogen economy. Fuel cell is considered to be the most promising new energy power system, and its research and development technology has been continuously upgraded, and it has become one of the competition focuses of the world's major automobile manufacturers. As an...

AI Technical Summary

Problems solved by technology

[0006] 1. The thermal system of a fuel cell vehicle is relatively complex. The heat dissipation load of the fuel cell is large but the heat dissipation temperature difference is small, while the operating temperature of the power battery is low and the temperature control accuracy is high. The operating temperature of the motor and air compressor is high. The heat management problem of power battery is more prominent

[0007] 2. Most of the existing technologies have relatively limited effect on efficient thermal management of fuel cells alone, and it is necessary to carry out coordinated and efficient management of the overall thermal system of fuel cell vehicles

If the PTC heater is used to consume battery power to heat the cooling water circuit of the fuel cell and power battery during cold start, it will increase the overall energy consumption of the system and damage the service life of the power battery

[0009] 4. Most of the existing technologies only recover and utilize waste heat from the heat produced by fuel cells, while ignoring the efficient utilization of waste heat from main heat-producing components such as power batteries, motor electrical systems, and air compressors
