Electrical Bicycle energy regeneration accessory feed
Technical field
The invention belongs to Electrical Bicycle Drive Control Technique field, further can be applied to elec. vehicle drive controlling fields such as electro-tricycle, battery-operated motor cycle.Relate to a kind of Electrical Bicycle energy regeneration accessory feed.
Background technology
At present, the Electrical Bicycle driving control system is made up of storage battery, motor and driving governor.Storage battery simultaneously provides the energy to motor and accessory equipment, and for example lamp, sensor, and the required power supply of controller utilize special charger that storage battery is charged, and storage battery adopts maintenance-free lead accumulator or Ni-MH battery etc. more.Behind the vehicle ' certain distance, battery tension charges a battery when dropping to certain lower limit.Because the accessory equipment operating voltage is lower than the motor rated voltage, battery tension press the configuration of motor required voltage, so storage battery supply with accessory equipment after need passing through the DC/DC step-down, as shown in Figure 1.
Summary of the invention
The object of the present invention is to provide a kind of Electrical Bicycle energy regeneration accessory feed, its characteristics are: except the main battery that motor moves the required energy is provided, and the interface circuit that also is provided with a boosting battery and forms by relay S1 and S2.
Characteristics of the present invention also are: boosting battery is connected with the accessory equipment direct current, to the accessory equipment power supply, when vehicle brake and descending, utilizes the electric energy that regenerative brake reclaimed of motor to charge.
Electrical Bicycle energy regeneration accessory feed of the present invention comprises motor, main storage battery, and main storage battery provides motor to move the required energy, and its voltage is pressed the configuration of motor rated voltage; Also comprise a boosting battery that is provided with in addition, wherein, boosting battery and accessory equipment direct connection, directly power to accessory equipment, auxiliary battery voltage is chosen by the accessory equipment operating voltage, also is connected with a driving governor between motor and main storage battery, and the driving governor power section is a three phase inverter bridge for permanent-magnet brushless DC electric machine, for the permanent magnet brush DC machine, its power section is a half-bridge structure; Main storage battery is connected by switch S 1 with driving governor, boosting battery is connected by switch S 2 with driving governor, according to car brakeing, normally move different running statees, shutoff and the conducting state of automatic switchover relay S1, relay S2, the electric energy that the motor regenerative brake is reclaimed charges to boosting battery by driving governor.
Because main battery is connected by relay S1 with driving governor, boosting battery is connected by relay S2 with driving governor, boosting battery and accessory equipment direct connection.Main battery provides motor to move the required energy, and its voltage is pressed the configuration of motor rated voltage; Auxiliary battery voltage is chosen by the accessory equipment operating voltage, does not therefore need the step-down through DC/DC, directly powers to accessory equipment.
When vehicle normally moves, relay S1 conducting, relay S2 turn-offs, and main battery provides motor to move the required energy by S1 and driving governor, and boosting battery is directly to the accessory equipment power supply, and two cover circuit are independent fully.
During car brakeing, relay S1 is turn-offed, relay S2 conducting, as shown in Figure 4.Because car brakeing does not need main battery to power to motor, and the main battery feed circuit are cut off.Machine operation is in the electrical generator operating mode constantly for this, and the motor regenerated energy is reclaimed by boosting battery by relay S2, and powers to accessory equipment.In addition, relay S1 turn-offs, and cuts off the electrical link of main battery and motor, guarantees that feedback energy charges to boosting battery.
Because the accessory equipment power consumption is less, so the regenerative brake of motor can satisfy the charging of boosting battery basically, so just do not need to be equipped with in addition special charger.Driving governor utilizes the electric energy drive motor in the power accumulator when the Electrical Bicycle cruising, and then the driving bicycle advances; When vehicle brake and descending, make machine operation in the electrical generator operating mode, the gravitional force loss when kinetic energy during with bicycle running and descending is converted into electric energy and is stored in the subsidiary battery, provides accessory equipment the required energy.
The present invention can save the DC/DC dropping equipment in the drive system, because the low capacity lead-acid storage battery is cheap, has therefore reduced the vehicle cost; Owing to make the energy of regenerative brake feedback obtain effective utilization, therefore when the raising Electrical Bicycle once charges travelled distance, also save the energy; In addition, owing to adopted the regenerative brake of motor, therefore reduced the wearing and tearing of mechanical brake part, prolonged the life-span of Electrical Bicycle, brake noise also decreases simultaneously; Improve the Electrical Bicycle technology content, enhance one's market competitiveness.

The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing and contriver.The present invention is described in further detail.
The present invention is a kind of later-model Electrical Bicycle energy storing mode, and promptly main battery provides motor to move the required energy, and its voltage is pressed the configuration of motor rated voltage; Other disposes a subsidiary battery, and this battery directly is connected with accessory equipment, and its voltage is chosen by the accessory equipment operating voltage, does not therefore need the step-down through DC/DC, directly to the accessory equipment power supply, as shown in Figure 2.
Because the accessory equipment power consumption is less, so the regenerative brake of motor can satisfy the charging of boosting battery basically, so just do not need to be equipped with in addition special charger.Driving governor utilizes the electric energy drive motor in the power accumulator when the Electrical Bicycle cruising, and then drives bicycle and advance, and boosting battery is powered to accessory equipment, and two cover circuit are isolated fully; When vehicle brake and descending, make machine operation in the electrical generator operating mode, the gravitional force loss when kinetic energy during with bicycle running and descending is converted into electric energy and is stored in the subsidiary battery, provides accessory equipment the required energy.
