Description of the drawings
Fig. 1 is that embodiment charging unit forms schematic diagram.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail：
Embodiment, with reference to attached drawing 1, a kind of electric vehicle charging device, including charger body 100 and remote temperature collector
200, charger body 100 includes the first micro controller module 101 and the first nothing being connect with the first micro controller module 101
Line RF receiving and transmission module 102；Remote temperature collector 200 includes shell and sets circuit board inside the shell, and circuit board includes the
Two micro controller modules 201 and the temperature sensor 203 and second being connect respectively with the second micro controller module 201 are wirelessly penetrated
Frequency transceiver module 202；The periodically control temperature sensor 203 of second micro controller module 201 detects electric vehicle part temperatures, with
The second radio frequency transceiving module 202 is controlled externally to send afterwards wireless including collector unique identifier, temperature parameter
Signal；First radio frequency transceiving module 102 receives wireless signal and transmits it to the first micro controller module 101, and first
Micro controller module 101 carries out the collector unique identifier in wireless signal and 100 unique identifier of charger body pair
Than verification, it is verified rear storage temperature parameter and is compared itself and preset threshold value, if more than threshold value, first
Micro controller module 101 controls charger body 100 to take safeguard measure.
In the present embodiment, although charger body 100 and remote temperature collector 200 are two individuals, the two is real
For a product, not only bundle sale together, but also there is one-to-one communication binding, complete function built in manufacture between the two and need
Wanting the two, cooperation could be realized together.
Temperature sensor 203 is preferably using patch type temperature sensor 203, for the first time in use, according to practical electric vehicle
Interior accumulator quantity and other needs draw the patch type temperature sensor 203 of respective numbers from remote temperature collector 200
It is pasted onto the component easily to generate heat in the Storage Battery Top Cover surface, harness surface and other charging processes of electric vehicle.Work as charger
Ontology 100 detects when carrying out charging behavior, and charger body 100 can be attempted to be built with remote temperature collector 200
It is vertical to write to each other.Then the temperature sensor 203 in remote temperature collector 200 starts collecting temperature, when the temperature detected
During no more than first threshold, the second micro controller module 201 controls the second radio frequency transceiving module 202 to be sent with the period 1
Otherwise wireless signal sends wireless signal with second round；Period 1 is more than second round, in the present embodiment, period 1
Preferably 1 minute, second round was preferably 30 seconds or 20 seconds.Under normal circumstances electric vehicle charging when inside component fever not
It can be more than first threshold, if it exceeds it may be considered that there are abnormal heating situation, more frequent detection be needed to prevent temperature mistake
Fast raising generates damage.
After charger body 100 receives wireless signal, will wherein temperature parameter it be compared with threshold value, if temperature parameter surpasses
First threshold is crossed, then the first micro controller module 101 control charger body 100 reduces charging voltage；After charging voltage reduces
Theoretically temperature should have a degree of decline, if after a certain period of time, the temperature parameter that charger body 100 receives is still
So in rising and more than second threshold, then the first micro controller module 101 control charger body 100 takes power-off measure；
First threshold is less than second threshold.
In the present embodiment, charger body 100 further includes the voice module 106 being connect with the first micro controller module 101,
101 control voice module 106 of the first micro controller module, which is reported, after charged state variation or when there are abnormal conditions currently fills
Electricity condition sends out alarm voice.Present charge state include start to charge up, charge end etc. prompt tones, alarm voice including because
Charger body overheat, overvoltage, overcurrent power-off voice, when overheating power-off voice because of temperature sensor and auto-ignition occurs
Alarm voice.It is to be understood that after charger body 100 takes power-off measure, can't be acquired immediately with remote temperature
Device 200 disconnects communication, still will continue to receive the wireless signal of remote temperature collector 200, until temperature declines and tends to be steady
It is fixed, in order to when ensuring to occur the auto-ignition that power-off can not prevent, i.e., charger body 100 receives electric vehicle portion
When part temperature is more than third threshold value, alarm voice can be sent out in time and reminds periphery crowd, third threshold value is higher than second threshold.
Battery feed power supply may be used in remote temperature collector 200, can also use included battery powered, this implementation
Using included battery powered in example, advantage connects electric power storage without remote temperature collector 200 additionally is drawn positive and negative connector
Pond positive and negative anodes reduce installation difficulty and foreign voltage interference, and remote temperature collector 200 itself is set using low-power consumption
Meter is used using that can meet several years from charged pool, substantially suitable with the service life of charger body 100.
