Description
Technical field
It is rapidly heated control method the present invention relates to a kind of Vehicular dynamic battery.
Background technique
An important component of the power battery pack as new-energy automobile, under extremely cold environment in use process can because
Battery itself low-temperature characteristics determines its charging and discharging capabilities, so that battery temperature is lower, power battery pack is unable to normal use, vehicle
Oil consumption under low temperature is increased, this needs the additional thermal management scheme progress battery that increases to be rapidly heated, to quickly improve power electric
The dynamic property of Chi Bao needs additional increase components cost although can quickly improve battery temperature in this way, costly,
It is unfavorable for long term growth；And in the prior art, it is usually all by increasing battery for the way of battery pack rapid warm raising control
Heating device heats battery, this needs to consume larger part energy, is a challenge for vehicle economy, and
In battery heating process, uneven heating between battery can be caused, thus cause cell degradation, it is final to influence battery pack performance and electricity
Wrap the service life in pond.
Summary of the invention
The present invention is intended to provide a kind of simple possible, battery heat up quickly and the Vehicular dynamic battery of energy saving quickly rises
Warm control method.
The present invention is realized by the following scheme:
A kind of Vehicular dynamic battery is rapidly heated control method, it is characterised in that: sequentially includes the following steps:
I first control panel CPU1 obtain battery pack total voltage, battery pack total current, battery module voltage and battery in real time
Packet temperature, according to the battery pack total voltage, battery pack total current, battery module voltage real-time estimation battery pack acquired
SOC；
II second control panels judge the size of initial battery pack SOC, if battery pack SOC is greater than the first limit value A or electricity
SOC is wrapped between the second limit value of limit value B~first A in pond, then the second control panel control motor actively rotates so that battery
Being discharged to battery pack SOC is the second limit value B, executes step III later；If battery pack SOC is less than the second limit value B, second
Control panel controls engine output and increases, and controls engine and drag rotating motor that battery is made to charge to the first limit value A, it
Step IV is executed afterwards, wherein the first limit value A is greater than the second limit value B；
III second control panels first control engine and drag rotating motor that battery is made to charge to the first limit value A, later control electricity
Owner's turn is dynamic so that battery discharge is to the second limit value B, recycles repeatedly, until battery pack temperature reach -10 degree with
On, i.e., battery pack allows charge and discharge peak power to be more than or equal to 15Kw at this time, can meet the requirement of vehicle dynamic property；
IV second control panels first control motor, and actively rotation is so that battery discharge is to the second limit value B, and control is started later
Machine drags rotating motor that battery is made to charge to the first limitation A, recycles repeatedly, until battery pack temperature reaches -10 Dus or more,
I.e. battery pack allows charge and discharge peak power to be more than or equal to 15Kw at this time, can meet the requirement of vehicle dynamic property；
The first limit value A is 70%；The second limit value B is 30%.
The battery pack total voltage, the acquisition frequency of battery module voltage are 20ms/ times, the battery pack total current
Obtaining the frequency is 10ms/ times, and the acquisition frequency of the battery pack temperature is 100ms/ times.
Data information in first control panel CPU1 is transmitted in the second control panel CPU2 by CAN communication.
Under extremely cold low temperature environment, the present invention is turned by controlling motor active rotation, passively dragging, to realize that battery is put
Electricity, charging control battery pack SOC always in the second limit value B and the first limit value by carrying out concussion charge and discharge to battery pack
Between A, constantly charge, in discharge process in battery, according to the characteristic of battery itself internal resistance, battery itself generates heat, from
And battery pack temperature constantly rises, battery pack temperature rise to -10 Dus or more reach corresponding peak power after, that is, say
Bright battery can substantially meet the requirement of vehicle dynamic property.
Vehicular dynamic battery of the invention is rapidly heated control method, and simple possible carries out concussion charge and discharge using to battery
For electricity so that the mode of battery nature heat improves battery temperature, the battery temperature rate of climb is fast, can save energy consumption, Er Qie electricity
The electrochemistry Self-heating in pond avoids the uneven heating problem of external heating bands, improves battery consistency, guarantees battery energy
Quick normal use can extend the service life of battery pack, while can save the components cost and power consumption of battery heating system,
Improve vehicle dynamic property and economy.
