For the optimum performance for maintaining lithium battery, battery the temperature inside the box should be controlled in 20 DEG C -35 DEG C, lithium battery heat-insulation system
It is divided into cold control system and temperature control system two parts.
Temperature control system is when battery box temperature sensor detects battery the temperature inside the box≤20 DEG C, in ECU micro treatment module
Control under, door leaf is opened, by blower be lithium battery blowing hot-air heated, the blower interior have heating wire, the wind
Machine state is divided into that blower stops, blower send hot wind, blower send cold wind, and the heating wire work generates heat, it can be achieved that blower send heat
Wind；The heating wire does not work, and does not generate heat, realizes that blower send cold wind；ECU micro treatment module is adopted by each temperature sensor
The temperature information of collection carries out operation and processing, carries out intelligent control to fan condition, when motor temperature sensor feedback motor week
When enclosing hot gas and reaching 20 DEG C, exhaust fan extracts the hot gas around motor under the control of ECU micro treatment module and heats to lithium battery；
When battery box temperature sensor detects battery the temperature inside the box >=25 DEG C, door leaf is closed, blower stops, exhaust fan stops working, and is stopped
Heating to lithium battery, battery case carry out keeping warm mode.
Cold control system is when battery box temperature sensor detects battery the temperature inside the box >=35 DEG C, in ECU micro treatment module
Control under, door leaf is opened, and blower is in blower and send cold wind working condition, and when battery the temperature inside the box≤30 DEG C, door leaf closed, blower
The working condition stopped, battery case carry out keeping warm mode；
Cold control system is when battery box temperature sensor detects battery the temperature inside the box >=35 DEG C, in the control of ECU micro treatment module
Under system, enter condenser pipe under the promotion that the condensed water in water tank passes through kinetic pump, cool down for lithium battery, then flow back into cooling fin drop
Temperature；When battery the temperature inside the box≤30 DEG C, under the control of ECU micro treatment module, kinetic pump stops working, by not fluidly
Condensed water and battery case realize the lithium battery heat preservation of long period.
In the parked state of environment temperature >=20 DEG C, solar panel converts solar energy into electrical energy to be mentioned for exhaust fan
For power, air sultry in battery case is discharged, the circulation by air is that lithium battery cools down；In ECU micro treatment module
Control under, blower send cold wind be lithium battery cool down；
In driving states, solar panel is converted solar energy into electrical energy, intelligently voltage boosting and rectification by solar panels
Circuit is battery charging.
Water tank is the excessive component of a storage condensed water, has certain volume, facilitates the storage of condensed water.
Battery case has heat insulation function, and when temperature is low, prevention heat spreads out of, radiates and keeping temperature not reduces, in temperature
Heat is prevented to be passed to and temperature is kept not increase when high.
The function of exhaust fan is by the intelligent control of ECU micro treatment module, to suck extraneous air, battery case is discharged
Interior sultry air, to achieve the effect that ventilated, cooling.
The function of air inlet pipe filter screen and exhaust fan filter screen is to prevent the impurity in outside air from entering battery case, keep away
Exempt from that lithium battery is caused to corrode.
The effect of kinetic pump: pushing the condensate water circulatory in water tank, keeps the condensate water circulatory to cool down through cooling fin continuous
It is lithium battery cooling into condenser pipe.
1. the symmetry hysteretic characteristic process that ECU micro treatment module intelligent control blower send hot wind:
(1) rises from temperature≤20 DEG C in the battery case, then when between 20 DEG C -25 DEG C, door leaf is opened, blower send hot wind and
Heat is generated, guarantees the circulation of hot wind, is heated for battery case；When battery the temperature inside the box >=25 DEG C, door leaf is closed, and blower stops, electricity
Pond case carries out keeping warm mode；
(2) battery the temperature inside the box is reduced from >=25 DEG C, then arrives the process between 20 DEG C -25 DEG C, and door leaf closes, and blower stops, battery
Case is in heat preservation operating condition；Until temperature≤20 DEG C, door leaf are opened, blower is in blower and send hot wind state, heats for battery case；
(3) temperature is between 20 DEG C -25 DEG C, and blower, door leaf keep former operating condition or state, it then follows symmetry hysteretic characteristic.
2. the symmetry hysteretic characteristic process that ECU micro treatment module intelligent control blower send cold wind:
(1) declines from temperature >=35 DEG C in the battery case, then when between 30 DEG C -35 DEG C, door leaf is opened, and blower send cold wind, is guaranteed
The circulation of cold wind declines temperature in battery case；When battery the temperature inside the box≤30 DEG C, blower stops working, and door leaf closes, battery
Case carries out keeping warm mode；
(2) process when increasing, then arriving between 30 DEG C -35 DEG C from temperature≤30 DEG C in battery case, blower stops, door leaf closes, electricity
Pond case carries out keeping warm mode, until temperature >=35 DEG C, door leaf are opened, blower send cold wind, declines temperature in battery case；
(3) battery box temperature is between 30 DEG C -35 DEG C, and blower, door leaf keep former operating condition or state, it then follows symmetry hysteresis is special
Property.
3. the symmetry hysteretic characteristic process of ECU micro treatment module intelligent control power pump work:
(1) for when declining in battery case from temperature >=35 DEG C, then arriving between 30 DEG C -35 DEG C, power pump work pushes water tank
Interior condensate water circulatory makes the condensate water circulatory to cool down through cooling fin constantly enter the cooling of condenser pipe lithium battery；Work as battery
