Abstract

The invention discloses a hybrid electric vehicle system and battery application thereof. The hybrid electric vehicle system comprises a generator, a battery, and an electric motor and the invention also discloses the battery application of the hybrid electric vehicle system.

Description

A kind of hybrid-power electric vehicle system and battery thereof use
Technical field
A kind of hybrid vehicle dynamical system, comprises electromotor, battery, motor and battery thereof and uses.
Background technology
The research of electric automobile shows, its energy efficiency has exceeded gasoline automobile. Particularly in city operations, automobile loiters, and travel speed is not high, and electric automobile is more suitable. Electric automobile does not consume electricity when stopping, and in braking procedure, motor can be automatically converted to electromotor, it is achieved the recycling of energy during braking deceleration. Some research shows, same crude oil, through thick refining, delivers to power plants generating electricity, through being filled with battery, then being driven automobile by battery, its energy utilization efficiency becomes gasoline than through refine, drive automobile high then through gasoline engine, be thus advantageous to save the energy and reduce the discharge capacity of carbon dioxide.
On the other hand, the application of electric automobile can efficiently reduce the dependence to petroleum resources, limited oil can be used for prior aspect. Can be converted by coal, natural gas, waterpower, nuclear energy, solar energy, wind-force, tide equal energy source to the electric power of accumulator charging. In addition, if charged to accumulator night, it is also possible to avoid peak of power consumption, be conducive to electrical network balanced load, reduce expense.
Electric automobile is internal-combustion engines vehicle simple in construction relatively, operating, drive disk assembly few, maintenance amount is little. When adopting induction alternating current (AC) motor, motor service free is safeguarded, it is often more important that electric automobile is steerable.
Instantly electric automobile is still not as internal-combustion engines vehicle technical perfection, and especially the life-span of electrical source of power (battery) is short, and use cost is high. The energy storage capacity of battery is little, and once after charging, distance travelled is undesirable, electric motor car expensive.
Summary of the invention
The battery cost of current electric automobile is high, and the charging interval is long, and once charging distance travelled is remote not. Some is local does not install an electromotor additional at automobile and provides and charge the battery to solve the problems referred to above. It is used for increasing distance travelled of once charging. Install additional and after electromotor offer charges the battery, do not worry that the electricity of battery looks for trailer without worrying that electricity deficiency looks for charging station everywhere after exhausting. If installation diesel-driven generator, the price of the every kilowatt hour of diesel generation is at about 1 yuan, and this price charging stations more expensive than some charging stations are cheap, and some charging station service charge will 1 yuan of additional electricity charge of every kilowatt hour. Diesel-driven generator uses the words that frequency is not high can use gasoline engine. Increase a small power generator power at 1��40 kilowatt. Distance travelled can be greatly increased, increase battery life greatly simultaneously.
Within travelling 30��70 kilometers currently without a suitable daily life of automobile dynamic system and work etc., need distance to travel more than 30��70 kilometers once in a while and go back home, be on home leave and tourism etc.
Current charging electric car device charging be all in any case the electricity of battery be flushed to full till and do not take into account needs (if operating range is comparatively short) and the battery life needs that automobile batteries uses. And the best using method of battery is not so, for instance lithium battery should be so:
1. do not overcharge and cross and put, overcharge and cross and put the life-span that all can be substantially reduced lithium battery. General electricity just should start to charge up lower than about 20%, and Meizu is arranged on 20% low capacity prompt and is also based on this reason, and putting the chemism that can reduce battery causes that energy storage reduces excessively. 2 batteries should pull out charger after being full of in time, a lot of chargers are all write " supplementing one to two hours after being full of more preferably ", such method of filling can allow stand-by time increase really, but the life-span of battery can be substantially reduced, original battery can rush to be put 500 times, so with it is possible to can only with 300 times. 2. the optimum life span of lithium battery is to be always maintained at the electricity of 20%-80%, and under such state, service life of lithium battery is the highest, and what charging system on famous Hubble Telescope was arranged is: when battery electric quantity begins to charging lower than 80%, just stop charging higher than 90%.
In sum, if you can allow your battery be always held at the electricity of 20%-80%, then the battery that originally can only use one or two years just can with 1 year.
In order to solve above-mentioned application scenarios.
The present invention provides the scheme of a kind of economy to solve problem above.
Use battery maximum can travel 30��70 kilometers, use electromotor to design 70 kilometers per hour by the technical standard of upper high speed. Long-time relatively short distance uses and can be pulled down by generating set. Generating set is designed to can the mode of easy disassembly, can dismantle within half an hour to 2 minutes, install. Use by battery life optimum, use scope at 20%-80%. Consider that this scope can be widened by the use environment of electric motor car, 10%-95%. It is pure electronic that short distance travels use, and distance uses distance beyond battery life optimum, and battery+electromotor is used in conjunction with.
Battery electric quantity can be full of and make power consumption to zero under performance mode by automobile, for instance lithium battery is always held at the electricity of 20%-80%.
Battery charge and power consumption can be arranged on optimal mode by automobile under life pattern.
Automobile charger can arrange and temporally automatically select charging current to protect battery.
Automobile charger can be arranged by the current charges the longest by battery life to protect battery.
Automobile charger can arrange the maximum that battery electric quantity is flushed to longest-lived scope to protect battery.
It is embodied as
Such as Fig. 1Shown in
The unidirectional current that DC generator sends is directly connected to battery system and battery can be charged and provide electric energy to motor, and charging voltage is by the adjustment of field excitation of electromotor.
When battery electric quantity is 20% or zero, DC motor control device locking peak power, controls power less than or equal to generator power.
