Abstract

The invention discloses an automobile secondary energy storing device based on a super-capacitor and a control method. The automobile secondary energy storing device based on the super-capacitor comprises a super-capacitor module, a super-capacitor management unit, a step-down DCDC and a step-up DCDC. One end of the super-capacitor module is connected with the super-capacitor management unit through a hard wire. The other end of the super-capacitor module is connected with a generator, a load, a storage battery and a starter motor respectively through hard wires. One end of the step-down DCDC is connected with the super-capacitor management unit through a hard wire. The other end of the step-down DCDC is connected with the generator, the load, the storage battery and the starter motor respectively through hard wires. One end of the step-up DCDC is connected with the super-capacitor management unit through a hard wire. The other end of the step-up DCDC is connected with the generator, the load, the storage battery and the starter motor respectively through hard wires. The super-capacitor management unit is also in communication with an engine control unit through a CAN bus. The automobile secondary energy storing device based on the super-capacitor and the control method can be applied to a non-hybrid power passenger vehicle with an internal combustion engine for supplying power.

Description

technical field [0001] The invention belongs to the vehicle energy management technology, and in particular relates to a secondary energy storage device and a control method for a vehicle based on a supercapacitor. Background technique [0002] The automobile industry is an important pillar industry of the national economy and plays an important role in the development of the national economy and society. With my country's sustained and rapid economic development and accelerated urbanization, the demand for automobiles will continue to grow for a long period of time in the future, and the resulting energy shortage and environmental pollution will become more prominent. Accelerating the cultivation and development of energy-saving vehicles and new energy vehicles is not only an urgent task to effectively alleviate energy and environmental pressure and promote the sustainable development of the automobile industry, but also a strategic measure to accelerate the transformation ...
