The driver comprises a motor and at least two lithium batteries; each lithium battery is connected with a voltage balancing module; the lithium batteries are connected in series respectively; the voltage balancing modules are connected together in series; and the motor is a brushless permanent-magnet DC dual-stator disk-type motor. The lithium batteries connected in series have balanced voltage, and the motor has large torque, small volume and light weight.
Description
Technical field
The present invention relates to a kind of Electric Vehicle power system.
Background technology
At present, for the environment and the limited resources of society, automobile industry strides forward towards the industry direction of electronlmobil, and electronlmobil can effectively reduce energy consumption, realizes zero-emission substantially, and zero pollutes.The core of electronlmobil is exactly its power-driven system, but present electronlmobil lithium cell series connection back can cause Voltage unbalance because of the resistance difference when discharging and recharging.The electrical motor of electrical automobile is in order to satisfy the high load capacity of automobile, must the big electrical motor of installation power, but high-power electrical motor volume and weight are all bigger.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, designed and developed out the lithium cell balance of voltage after a kind of series connection, motor torque is big, and volume is little, lightweight electric automobile driving apparatus.
The present invention is achieved by the following technical solutions:
A kind of pure electric automobile actuating device comprises the electric drive system that is made of electrical motor and lithium cell group, and the both positive and negative polarity of described each lithium cell of lithium cell group connects a balance of voltage module respectively, and balance of voltage module is cascaded by line of balance.
A kind of pure electric automobile actuating device, described motor are the two stator disc type electric machines of brush-less permanent magnetic direct current.
Drive for EV technology of the present invention adopts novel 120V, and the two stator disc type electric machines of the novel brush-less permanent magnetic direct current of 10KW-15KW are in light weight, have only the 10-17 kilogram, and moment of torsion is big, and overload capacity is strong.Battery pack is made up of ferric phosphate lithium cell, the both positive and negative polarity of every battery connects a dc voltage balance module, the line of balance of every balance module links to each other then, can realize 2-5V, the voltage self-equalizing of the serial lithium battery of 200-400AH, solve series-connected cell because of the internal resistance difference, discharged and recharged a difficult problem that causes Voltage unbalance.
Description of drawings
Accompanying drawing is an electronlmobil electric powerplant structured flowchart.
The specific embodiment
Shown in accompanying drawing.The present invention includes the electric drive system that is made of electrical motor 1 and a plurality of lithium cell 2, the both positive and negative polarity of each lithium cell 2 connects a balance of voltage module 3, and lithium cell 2 is cascaded respectively, and balance of voltage module 3 is cascaded respectively.Motor 1 is the two stator disc type electric machines of brush-less permanent magnetic direct current.Drive for EV technology of the present invention adopts the two stator motors of Novel DC brushless, permanently, and is in light weight, has only the 10-17 kilogram, and moment of torsion is big, and overload capacity is strong.Each lithium cell 2 of lithium cell group links to each other with the line of balance of a balance module 3, can realize 2-5V, and the voltage self-equalizing of the serial lithium battery 1 of 200-400AH has solved series-connected cell because of the internal resistance difference, is discharging and recharging a difficult problem that causes Voltage unbalance.
