Abstract
The invention relates to a energy recovering and converting system of an electric vehicle, in particular to a brake energy recovering system of an electric vehicle. The brake energy recovering system of the electric vehicle comprises a conversion contact switch for controlling a three-phase alternating current intermediate relay, the three-phase alternating current intermediate relay, a two-speed electric motor, a generating dual-purpose motor, a three-phase alternating current rectifier and an electric vehicle storage battery which are connected in sequence. The brake energy recovering system can rectify excessive energy into the optimal charge voltage required by a storage battery pack and then directly output electric energy to the storage battery pack of the electric vehicle for charging and has over 85 percent of recovering rate, thereby realizing the recycling of energy. The invention not only saves energy source to some extent, but also has the advantages of simple structure, high energy conversion rate, strong universality and low cost.
Description
Technical field
The present invention relates to a kind of battery-driven car energy recovery conversion system, particularly a kind of brake energy recovering system of electric vehicle.
Background technology
In the today of advocating energy-saving protective natural oil resource, battery-driven car relies on its distinctive advantage and enjoys the customer to favor.Present battery-driven car mainly contains: pure electric automobile, hybrid-power electric vehicle, tour bus, Electrical Bicycle, battery-operated motor cycle etc., and which kind of battery-driven car no matter, elec. vehicle is all wanted consuming cells group energy in the process of moving.At car retardation, descending, glancing impact, when acceleration pedal is got back to when not quickening the position, braking energy then changes into heat energy or other forms of energy and loses, and power transmission loss is big, owing to can't realize the recycling once more of energy, this has not only caused the waste of the energy on certain degree, and has increased the cost of hybrid-electric car virtually.For the recovery of battery-driven car excess energy, also exist multiple solution at present, but such scheme is all not ideal enough on structure design.When real-world operation, complicated and the otherwise reason owing to system architecture, make the voltage after the rectification be lower than the voltage of battery of electric vehicle group, owing to can't directly charge to the electromobile battery group, therefore also must boost after the rectification, not only cost is high and big, the poor reliability of recovery loss, and this has limited the excess energy utilization of battery-driven car to a certain extent.
Summary of the invention
The objective of the invention is to solve the deficiencies in the prior art, and provide a kind of simple in structure, energy conversion rate height, the brake energy recovering system of electric vehicle that highly versatile and cost are low.
The objective of the invention is to be achieved by the following scheme: brake energy recovering system of electric vehicle, it is characterized in that: the changeover contact switch that comprises a control three-phase alternating current intermediate relay, one three-phase alternating current intermediate relay, electronic, the electricity generating dual purpose motor of one double speed, one three-phase alternating current rectifier, one electromobile battery, changeover contact switch, three-phase alternating current intermediate relay, the double speed of control three-phase alternating current intermediate relay is electronic, electricity generating dual purpose motor, three-phase alternating current rectifier and electromobile battery link to each other successively.
Described double speed is electronic, electricity generating dual purpose motor includes electronic winding and the generating winding.
Described three-phase alternating current intermediate relay comprises two groups of changeover contacts, often opens for one group to be open contact, and one group is normally closed contact.
The beneficial effect that the present invention obtains: when acceleration pedal is got back to when not quickening the position, brake energy recovering system directly charges these electric energy after unnecessary energy can being rectified into the required optimum charging voltage of battery pack to the electromobile battery group, the percent recovery is greater than 85%, thereby realize the utilization once again of energy, this has not only saved the energy to a certain extent, and simple in structure, the energy conversion rate height, highly versatile, cost are low.
