Description
Technical field
The present invention relates to many battery driven coaxial motor system.
Background technology
Environmental problem receives people's attention day by day, and electric motor car is as the free of contamination vehicles, and to building sustainable development society, the home of protecting us to survive has great importance.Battery pack is as the key components that drive the electric motor car operation, and the development of electric motor car is had crucial effects.
The current driving force battery all also has very big deficiency at aspects such as consistency, life-spans, for example in long-term use, the consistency of battery can go wrong, and causes battery capacity sharply to descend; Battery pack in use also the single battery capacity occurs far below same Battery pack through regular meeting; At this moment continue again to use and to cause major injury to whole battery group; Yet the battery pack of electric automobile all is to use through connection in series-parallel together, changes waste battery and will become very complicated.
The voltage of the battery pack that electric automobile uses has generally all reached several hectovolts, and operating personnel might be wounded by high pressure when assembling or keeping in repair for battery pack.
Summary of the invention
Shortcomings and deficiencies to prior art; The invention provides a kind of many battery driven coaxial motor system; In the motor is multiple stators or many rotor coaxials structure, and a plurality of battery pack drive different stators and rotor respectively, thereby realizes different motor is controlled; Can improve the consistency and the extending battery life of electrokinetic cell, it is convenient that battery pack also becomes when changing, and because the voltage of baby battery group is not high, it is also as safe as a house to operate.
For realizing above-mentioned purpose; The present invention adopts following technical scheme: a kind of many battery driven coaxial motor system comprises a plurality of battery pack, general control system, battery management system master controller, a plurality of battery management system slave controller, motor master controller, a plurality of electric machine controller and an a plurality of motor; A plurality of battery pack and a plurality of battery management system slave controller connect one to one; A plurality of battery management system slave controllers and a plurality of electric machine controller connect one to one; General control system is connected with the motor master controller with the battery management system master controller respectively; The motor master controller is connected with a plurality of electric machine controllers respectively; The battery management system master controller is connected with a plurality of battery management system slave controllers respectively; A plurality of electric machine controllers and a plurality of motor connect one to one.
Be provided with stator and rotor in each motor, said stator is connected with electric machine controller with rotor.
Said a plurality of motor is a coaxial motor.
Said motor charges to the battery pack inversion through electric machine controller.
Principle of the present invention is following: do not need gear box, according to power demand, general control system is connected different battery pack pushing motors.And for the motor load of non-constant power demands such as electric motor car; The more important thing is that battery pack can divide into groups to motor electric power to be provided, number can be selected according to power demand, and both can use simultaneously; Also can timesharing use; Even can be in the output electric energy in some battery pack, and coaxial motor drive other motors through electric machine controller to other battery pack inversions chargings, thereby to the inconsistent equalization operation of carrying out of battery pack.Solved following technical problem: a kind of many battery driven coaxial motor of innovation ground proposition system; Can use different stator of a plurality of battery driven and rotor; The consistency of electrokinetic cell, life problems just can obtain very big alleviation like this, and battery pack is changing also very facility, in addition; The voltage of each baby battery group is not high, and operating personnel are as safe as a house when assembling or keeping in repair for battery pack.
By on can know, the present invention compared with prior art, its advantage and beneficial effect are:
1, the voltage of battery pack need not be too high, and the series-connected cell number is few, and the difficulty that battery management system (BMS) is managed each battery pack and the requirement of battery balanced property all reduce.
When 2, battery pack is unbalance, can also, compensate and equilibrium to low charged battery pack inversion charging by highly charged battery pack through coaxial mechanical energy coupling (perhaps couple electrical energy).
If 3 certain battery pack break down, it is just passable only to need to change the battery pack that breaks down, and cost reduces greatly, and changes conveniently.
