(6) Air-Conditioning Control Panel
Air-Conditioning Control Panel adopts the mode of man-machine interaction, and for control temperature and the mode of operation of operator's initialization system, described mode of operation includes: refrigeration mode, heating mode and automatic mode.Temperature and the mode of operation of setting are sent to entire car controller by CAN message by Air-Conditioning Control Panel.Some early warning information also can be fed back to Air-Conditioning Control Panel by entire car controller, it is simple to operator can understand the working condition of humidity control system at any time.
The control method embodiment of electric automobile energy saving humidity control system
Based on electric automobile energy saving humidity control system set forth above, a kind of control method that use this humidity control system is described below, as shown in Figures 2 and 3.
This humidity control system includes two electric heaters and three temperature sensors, electric heater be separately mounted to drive space left front and right after, sensor be separately mounted to drive space left front, right after and centre.Wherein be arranged on left front and right after sensor be mainly used in monitoring electric heater temperature, it is prevented that electric heater temperature is too high and burns out.The sensor being arranged on centre is mainly used in gathering driving indoor environment temperature.
Start after energy efficiency temperature adjustment system, when system high pressure starting state is normal, SOC more than 25%, DCDC output voltage normal (more than 24V), humidity control system can normally start.Operator set required temperature and mode of operation on Air-Conditioning Control Panel, set data are sent to entire car controller with CAN message by Air-Conditioning Control Panel, the data obtained are processed and analyze by entire car controller, then air-conditioning and electric heater is driven to run, power battery pack provides voltage for air-conditioning and electric heater, and air-conditioning and electric heater start to heat for driver's cabin or freeze.The mode of operation that in the present embodiment, operator set on Air-Conditioning Control Panel includes: heating mode, refrigeration mode and automatic mode.Below according to these three pattern, the specific works principle of this system is described in detail.
(1) heating mode
As shown in Figure 2, if the pattern that sets is as heating mode, the mode of operation set and set temperature value are sent to entire car controller by Air-Conditioning Control Panel, entire car controller obtains current indoor ambient temperature by sensor, and the temperature value in the temperature value of setting and current vehicle is contrasted, if set temperature value is more than current vehicle interior temperature, entire car controller output electrothermal driving signal is high level, make what connect between entire car controller and electric heater to add thermorelay adhesive, thus entire car controller sends heating signal to electric heater, start electric heater, simultaneously, electrokinetic cell provides high voltage by high voltage power distribution device for electric heater, electric heater starts to heat for driver's cabin.
(2) refrigeration mode
As in figure 2 it is shown, the operation principle for driver's cabin refrigeration is basic and to heat principle essentially identical.If the pattern that sets is as refrigeration mode, the mode of operation set and set temperature value are sent to entire car controller by Air-Conditioning Control Panel, entire car controller obtains current indoor ambient temperature by sensor, and the temperature value in the temperature value of setting and current vehicle is contrasted, if set temperature value is lower than current vehicle interior temperature, entire car controller output air-conditioning drives signal to be high level, make the refrigeration relay adhesive connected between entire car controller and air-conditioning, thus entire car controller sends cooling signals to air-conditioning, start air-conditioning, simultaneously, electrokinetic cell passes through DC-DC converter, high pressure converts to 24V low pressure power for electricity air-conditioning, air-conditioning starts to freeze for driver's cabin.
(3) automatic mode
Entire car controller obtains current indoor ambient temperature by sensor, suitable temperature according to setting in advance contrasts, then, determine to begin to warm up pattern or refrigeration mode, heating and refrigeration basic functional principle with above-mentioned " heating mode " and " refrigeration mode " according to the result of contrast.Therefore no longer repeat here.
Entire car controller can pass through BCM and BMS and obtain vehicle door status and battery SOC signal, if car door opening and car door opening exceed the setting time (as: 3 minutes), or electrokinetic cell SOC less than setting value time (in the present embodiment, chosen settings is 15%), disconnecting the relay that electricity air-conditioning is corresponding with electric heater, system is by stopping refrigeration or heating.
When entire car controller collect three temperature sensors meet or exceed set temperature value time, disconnect relay corresponding to electric heater, system stops heating.Meanwhile, alarm signal is sent to Air-Conditioning Control Panel by entire car controller, and is sent to car load instrument display alarm information with message form.When the sensor having monitoring electric heater reaches a high temperature alarming value (125 DEG C) simultaneously, entire car controller closes the heating of the two heater, until electric heater temperature is recovered to restarting temperature.When the temperature of this humidity control system is too high or other faults occur, alarm signal is sent to Air-Conditioning Control Panel, the flicker of fault indicating lamps on air-conditioning panel by entire car controller.Entire car controller is sent to car load instrument display alarm information with message form simultaneously.
This humidity control system is normal operation under ACC fire or ON fire.When normalizing or total fire; can pass through to stick up class's switch and force start and stop humidity control system; now, total fire connected by car load is that related device (such as motor integrated manipulator, BMS, BCM and Air-Conditioning Control Panel etc.) is powered so that it is can normal operation.Meanwhile, the DCDC in motor integrated manipulator by change voltage and be output as electricity air-conditioning or electric heater power.
