Description
[technical field]
The present invention relates to a kind of temperature-controlled process of power brick, especially, relate to a kind of temperature-controlled process having for the power brick of electronic bus.
[background technology]
Along with petroleum resources day by day reduce and the pollution of environment day by day serious, protection of the environment, energy-saving and emission-reduction have become current trend and trend in the world.Under this background, in recent years, take battery as main power source or the motor vehicle of partial power source (mainly comprise hybrid electric vehicle, plug-in hybrid electric vehicle, pure electric vehicle) engender and increasing, the carbon emission amount of motor vehicle is less than traditional combustion engine automobile, and the carbon emission of pure electric vehicle is even zero, and have the advantages that energy conversion efficiency is high, this makes people electric automobile is considered as to an important selection of following replace internal combustion engines car.
The power of current electric automobile is mainly selected lithium ion battery bag, and lithium ion battery bag is made up of multiple lithium-ion battery monomers, and the energy that current batteries of electric automobile bag stores is generally all larger, and particularly pure electric vehicle is all the more so.For example: for common family expenses pure electric automobile, such as daily output " LEAF " (daily output " listening wind "), its lithium ion battery bag energy storage 24kWh.And for more large-scale pure electric vehicle, for example pure electronic bus, its power brick energy storage generally, more than 200kWh, even can reach 300～400kWh.
For energy storage capacity huge electronic bus power brick like this, the heat management of its power brick is current technological difficulties, at present, the power brick of electronic bus mainly adopts the air-cooled heating of controlling battery, the bellows chamber is here drawn together natural wind and air-conditioner wind, there is fan in power brick operated by rotary motion, adopt fan to purge battery.
Consider for passenger's comfortableness, on current electronic bus, be substantially all equipped with air-conditioning, in summer and winter, freeze and heat for electric drive air-conditioning by power brick.In the winter time, due to ambient temperature lower (average is lower than 10 ℃), so the heating problem of power brick not serious is cooling without adopting air-conditioner wind to carry out power brick, the general fan that only need to open in power brick blows.But in summer, due to ambient temperature higher (average is higher than 20 ℃), the heating of power brick is more serious, so in the time of summer, generally need to adopt air-conditioner wind to carry out cooling to power brick.Drive air-conditioning is a larger load for power brick, and generally speaking, in the situation that opening air-conditioning summer, a charge operation mileage of electronic bus will shorten 1/3 left and right.
But at spring and autumn, ambient temperature is between 10 ℃～20 ℃ time, in order to save the electric weight of power brick, on general electronic bus, do not turn on the aircondition, at this time power brick does not obtain the cooling of air-conditioner wind, only rely on the fan in power brick to blow cooling, when ambient temperature higher (while approaching 20 ℃), and the temperature of the natural wind that fan purges out is higher, the heat of power brick and internal cell thereof is difficult to distribute in time, the temperature of battery can reach 40 ℃ even higher, can have influence on like this battery performance, even causes security incident.
[summary of the invention]
The object of this invention is to provide a kind of temperature-controlled process of electronic bus power brick, it can control the temperature of power brick in the time of spring and autumn preferably.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of power brick temperature-controlled process, described battery pack is in electronic bus, in described electronic bus, be provided with air-conditioning, described air-conditioning is driven by power brick, comprise at least 2 group fans in described described power brick, in described power brick, be provided with air-conditioner wind entrance, described temperature-controlled process comprises:
(1), in the time of T<10 ℃, open one group of fan;
(2), in the time of 10 ℃ <T<20 ℃, open at least two group fans;
(3), in the time of T>20 ℃, open one group of fan, air-conditioning, open air-conditioner wind entrance and exit;
Wherein, described T is atmospheric temperature.
As preferred technical scheme: described power brick comprises two groups of fans, in the time of 10 ℃ <T<20 ℃, opens two groups of fans.
As preferred technical scheme: described power brick comprises three groups of fans, (2) in the situation that, in the time of 10 ℃ <T<15 ℃, opens two groups of fans; In the time of 15 ℃ <T<20 ℃, open three groups of fans.
As preferred technical scheme: be provided with two air-conditioner wind entrances in described power brick, in the time of 20 ℃ <T<25 ℃, open an air-conditioner wind entrance, in the time of T>25 ℃, open two air-conditioner wind entrances.
First the technical program divides into ambient temperature spring and autumn (10 ℃ of <T<20 ℃), winter (T<10 ℃), summer (T>20 ℃),
Then the many groups fan in power brick is adopted to different control strategies, only adopt one group of fan to carry out cooling in winter in summer, it is air-cooled that in the time of spring and autumn, the many groups of employing fans carry out battery, thereby make to control preferably the temperature of power brick in the time of spring and autumn.
In preferred technical scheme, further by spring and autumn sky be divided into two levels.In the time that ambient temperature is lower (10 ℃ of <T<15 ℃), adopt two groups of fans to blow cooling, and in the time that ambient temperature is higher (15 ℃ of <T<20 ℃), adopt three groups of fans to blow cooling, can more accurately carry out heat management to power brick like this, can also in lower in ambient temperature (10 ℃ of <T<15 ℃), drive less one group of fan in addition, thereby saves energy, increases the course continuation mileage of electronic bus.
In the technical scheme being more preferably, further summer temp is divided into two levels, when ambient temperature is during in 20 ℃ <T<25 ℃, only open an air-conditioner wind entrance; And when ambient temperature higher (T>25 ℃), open two air-conditioner wind entrances, thereby it is enough cooling to guarantee that power brick can obtain, when ambient temperature is not very high, (20 ℃ of <T<25 ℃) controls by the cold blast rate of power brick in addition, and more cold wind is supplied with to compartment.
