Description
Technical field
The present invention relates to a kind of automobile starting supply unit based on lithium-ion capacitor and its start control method, belong to
Electric motor car energy technical field.
Background technology
Startup power supply mainly using lead-acid accumulator as automobile in the prior art, but but there is itself for battery
The defects of can not making up：Poor performance at low temperatures, high magnification fan-out capability produce irreversible influence, self discharge ability to itself
Compare high.
Determined by the architectural characteristic of battery, under low-temperature condition, the charge acceptance of battery, charge efficiency, capacity
It will decline, if electric vehicle load excessive（Heavy-current discharge）, long-time heavy-current discharge, the actual discharge capacity of battery will
It can become smaller.This is also the reason for all batteries is not ideal enough in use in the winter time.Internal storage battery DC internal resistance it is big
It is small to produce change with the change of environment temperature and use environment.Under low temperature environment particularly below -25 DEG C, electric power storage
The charge acceptance in pond seriously glides, or even does not reach it at all and start voltage；In addition, its discharge capacity will be with temperature
Reduction significantly decline, in some instances it may even be possible to discharge capability useless.When environment temperature is down to less than 0 DEG C, temperature often reduces by 10 DEG C, interior
Resistance about increases 15% or so, because sulfuric acid solution viscosity becomes big, increases sulfuric acid solution resistance, and has aggravated electrode polarization
Influence, accumulator capacity can be obviously reduced.
In normal conditions of use, starter is when the immediate current of startup is to run well several times of rated current, therefore
And cause battery instantaneous voltage to decline to a great extent, degradation.And battery fills as startup power supply after energy uses
It is longer the time required to electric；And battery can not use need discarded when, the environmental pollution such as heavy metal lead is serious, limits storage
The application of battery.
Meanwhile the moon self-discharge rate of battery is up to 30%, therefore, in long-term unused automobile, it is necessary to which every three months starts
Once, it is battery charging a period of time.This has equally been limited the application of battery.
In order to improve the performance of automobile starting power supply, start automobile using the mode of ultracapacitor multiple-connected battery,
Such as patent CN202429148U.Ultracapacitor has that capacity is big, power is high, long lifespan, low-temperature characteristics are good and pollution-free etc.
Feature, can be used in parallel with battery.The momentary high power that ultracapacitor is utilized during automobile starting is starter
Power supply, so greatly increases the service life of battery；However, the self-discharge rate of ultracapacitor itself is very big, substantially 3
It will be discharged, and this just greatly limit the use of ultracapacitor.
Lithium ion battery is compared with battery, it is apparent that its self-discharge rate is very low, substantially places 1 year, electricity
80% can also be maintained；The service life cycle of lithium ion battery is far above battery.Therefore, patent CN104037446A is directly used
Lithium ion battery substitutes battery as automobile starting power supply, but does not solve battery thoroughly yet as automobile starting power supply institute
The problem of existing, relate generally to the ability of high-power instantaneous discharge.
In addition, also another replaced type startup power supply device is using ultracapacitor substitution battery, such as specially
Sharp CN203827004U, CN202978396U.In such a system, the main function of battery is to be charged for ultracapacitor and be
In-car load supplying.The drawbacks of still no change ultracapacitor self discharge of this system seriously causes a large amount of energy losses,
Need to charge to ultracapacitor again before being again started up.
The content of the invention
The technical problem to be solved by the invention is to provide a kind of new automobile starting supply unit and its start controlling party
Method, the startup power supply device are based on lithium-ion capacitor, the automobile starting supply unit had high voltage holding capacity, used
The advantages that long lifespan, freedom from repairs, accurate control.
Lithium-ion capacitor uses lithium ion battery and ultracapacitor mixed structure, and its positive pole is using ultracapacitor
Positive pole, negative pole use the negative pole structure of lithium ion battery, have the high power density of ultracapacitor concurrently（Its power density is much larger than
Lead-acid accumulator）, long-life characteristics and lithium ion battery high-energy-density characteristic.There is very high voltage to keep energy for itself
Power, 25 DEG C of normal temperature are placed 3 months, and voltage declines≤5%；Wide use temperature range（-40℃~70℃）Safety in operation, reliable
Property.Therefore, lithium-ion capacitor can make up the shortcomings that battery completely, directly substitute battery as automobile starting power supply.
Based on lithium-ion capacitor possessed premium properties, the present invention proposes the automobile based on lithium-ion capacitor and opened
Dynamic device, the automobile starting supply unit mainly include：
