The invention discloses a
phase change energy storage liquid-cooled plate, a
battery pack active
heat management system and a control method. The
battery pack active
heat management system comprises battery modules, a temperature sensor, a
phase change energy storage liquid-cooled plate, a thermal conductive glue, a battery
management system, a
throttle opening sensor, a
brake opening sensor, a speed sensor, temperature sensor control harnesses, a power harness, other sensor harnesses, a control valve control harness,
control valves, and a water pump; the battery modules and the
phase change material
energy storage liquid-cooled plate are connected through the thermal conductive glue by stickiness; the phase change energy storage liquid-cooled plate and the battery modules are connected tothe temperature sensor; the temperature sensor is connected to the battery
management system through the control harnesses; the
throttle opening sensor, the
brake opening sensor and the speed sensorare connected to the battery
management system through the control harnesses; and the battery management
system controls the water pump and the
control valves according to the information transmittedfrom the sensors to control the overall temperature rise of the
battery pack, so as to increase the consistency of the battery pack. The invention has the characteristics of high flexibility, good heat dissipation effect and strong adaptability.
