Description
Technical field:
The utility model relates to a kind of power system of electric automobile, relates in particular to the independently-powered power system of electric automobile of a kind of many Battery packs.
Background technology:
Energy shock in the global range increasingly sharpens, and fossil energy faces exhaustion; Ecological deterioration, climate warming is more and more serious.See that from the angle of energy-conserving and environment-protective the development of electronlmobil has become the common recognition of global auto trade development.
The waste gas that electronlmobil work the time does not produce, pollution-free, zero-emission is that ten minutes is useful to the cleaning of environmental protection and air; Secondly the noise of electrical motor is also little than combustion engine; Electronlmobil is simple in structure than internal-combustion engines vehicle, and running, drive disk assembly is few, and the maintenance amount is little.The application of electronlmobil can effectively reduce the dependence to oil resources, can limited oil be used for prior aspect.Electric power to battery charge can be transformed by coal, natural fuels, waterpower, nuclear energy, solar power, wind-force, morning and evening tides equal energy source.So world wide is interior, especially developed country all formulating the electronlmobil strategy of this country, constantly releases various electronlmobils.However, electronlmobil meets with " battery bottleneck " restriction always, and long, battery of, energy prolongation few because of its mileages of continuation reasons such as the life-span is short in groups can not be accepted by the customer for a long time, exist industrialization to be difficult to a difficult problem that realizes for a long time.Wherein, the service life of battery after in groups makes the use cost of electronlmobil to reduce than the problem that shortens greatly in service life of cell especially, has seriously hindered the industrialized development of electronlmobil.
See from present observed data, the discharging and recharging number of times and can reach 1500 times of cell, but after a large amount of batteries is formed battery pack; Owing to exist difference between each monomer; These differences can cause that other monomer overcharges or puts excessively, and then cause the battery number of times that discharges and recharges in groups to significantly reduce in the process of battery set charge/discharge; Even damage, individual other monomer discharges and recharges number of times only to be had only 400 times.Directly caused the rising of the use cost of electronlmobil, the industrialization of electronlmobil has been had serious inhibition.
Summary of the invention:
In order effectively to reduce the group effect of electrokinetic cell; Prolong the service life of electrokinetic cell; Reduce the use cost of electronlmobil; The purpose of the utility model provides a kind of group effect of effective reduction electrokinetic cell, the independently-powered power system of electric automobile of many Battery packs that prolongs the service life of electrokinetic cell.
The technical scheme of the utility model realizes in the following manner:
The independently-powered power system of electric automobile of a kind of many Battery packs; It comprises micro processor, be controlled by the SPWM producer of micro processor, receive gate-drive module, the inversion module that is controlled by the gate-drive module controls, power battery pack, the electrical motor of SPWM generator driven signal; Electrical motor is a multi-winding motor, and power battery pack is many groups power battery pack of corresponding power supply with multi-winding motor.
Multi-winding motor is 500 groups of multi-winding motors within the winding, and power battery pack is the many groups power battery pack within corresponding 500 groups of supplying power.
Multi-winding motor is 100 groups of multi-winding motors within the winding, and power battery pack is the many groups power battery pack within corresponding 100 groups of supplying power.
Multi-winding motor is 50 groups of multi-winding motors within the winding, and power battery pack is the many groups power battery pack within corresponding 50 groups of supplying power.
Every Battery pack group is through cooresponding inversion module and the power supply of cooresponding motor winding separate connection.
Every group of inversion module is connected, receives SPWM generator driven signal through cooresponding gate-drive module and SPWM producer, and the SPWM producer is connected, is controlled by micro processor with micro processor.
Every group of inversion module also all is connected with the fault detection protection module, and the fault detection protection module is connected with micro processor.
Micro processor also is connected with display module, alarm module, setting load module.
The utmost point effect of the utility model is:
1, reduces the group effect of electrokinetic cell.
The utility model through electrokinetic cell is disperseed to use, reduces the interior quantity of group in groups, reduces the group effect of electrokinetic cell; Battery disperses usage degree high more, and group effect reduces obvious more.
2, prolong the service life of electrokinetic cell.
Since the minimizing of quantity in battery is organized in groups, the reduction of group effect, the number of times that discharges and recharges of battery obtains the actv. raising, when disperseing usage degree high, can be near the number of times that discharges and recharges of cell, and the actv. in service life of battery prolongs.
3, reduce the use cost of electronlmobil, promote the industrialization process of electronlmobil.
Battery cost in groups, the proportion that accounts for the electric automobile whole cost is very big, if battery is very short service life in groups, just means that the use cost of electronlmobil can't reduce.The prolongation in electrokinetic cell service life means that the use cost of electronlmobil has obtained reduction.Promote the industrialization process of electronlmobil.
4, reduce the cast anchor rate of electronlmobil on road, increase the reliability of electronlmobil.
When wherein one group breaks down, still can keep the power of car load, be unlikely to car load and cast anchor; Keep in repair very convenient.
