Abstract
The invention discloses a temperature detection device of an electric automobile adapter, which comprises an adapter, wherein a temperature sensor and a microprocessor are arranged on the adapter, and the temperature sensor is used for measuring the temperature of a main heating element in the adapter; the microprocessor is connected with the temperature sensor, and the microprocessor is used for processing the temperature data measured by the temperature sensor and carrying out information interaction between the microprocessor and the charging pile and between the microprocessor and the vehicle. The adapter temperature monitoring system can monitor the temperature of the adapter in time, inform the charging pile and the electric automobile, and avoid potential safety hazards caused by overhigh temperature rise of the adapter.
Description
Technical Field
The invention belongs to the electric automobile charging technology, and particularly relates to a temperature detection device of an electric automobile adapter.
Background
The propulsion of new energy electric automobile accords with national policy and trade development trend, along with the development of new energy automobile technique, the user is more and more high to the requirement of electric automobile convenience of charging, and the electric automobile of different interfaces uses and to fill electric pile need use the adapter when charging, but, the temperature of how to monitor the adapter is the problem of puzzlement in the trade always, if the temperature of unable monitoring adapter, electric automobile uses the adapter when charging will bring electric automobile and fill electric pile both sides' potential safety hazard.
To the adapter that does not have temperature detection, can't carry out the effective monitoring of temperature during the use, can only monitor respective temperature through the temperature sensor who fills electric pile and electric automobile itself, can't monitor the temperature of adapter, electric automobile can't know adapter temperature anomaly with filling electric pile.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to provide a temperature detection device of an electric automobile adapter, which can monitor the temperature of the adapter in real time.
The technical scheme is as follows: the temperature sensor measures the temperature of a main heating element in the adapter; the microprocessor is connected with the temperature sensor, and the microprocessor is used for processing the temperature data measured by the temperature sensor and carrying out information interaction between the microprocessor and the charging pile and between the microprocessor and the vehicle.
Fill through CAN line connection between electric pile and the vehicle, microprocessor inserts fills electric pile, CAN line between the vehicle, CAN in time inform the condition of generating heat of adapter and fill electric pile or vehicle.
The microprocessor accesses the CAN line by inserting nodes into a communication network of the CAN line.
The adapter is used for taking electricity from an auxiliary power supply of the charging pile.
The temperature sensor is PT1000 or NTC type.
Has the advantages that: compared with the prior art, the invention has the beneficial effects that: (1) the temperature of the adapter can be monitored in real time; (2) electric automobile can in time receive the unusual signal of adapter temperature with filling electric pile.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention is described in further detail below with reference to specific embodiments and the attached drawing figures.
As shown in figure 1, the intelligent charging system comprises an adapter, wherein a temperature sensor and a microprocessor are arranged on the adapter, the temperature sensor is used for measuring the temperature of a power terminal (DC +, DC-) of a main heating element in the adapter, in the embodiment, the adapter takes electricity from an auxiliary power supply (A +/A-) of a charging pile, and the temperature sensor is PT1000 or NTC model; the microprocessor is connected with the temperature sensor, the microprocessor is used for processing temperature data measured by the temperature sensor, the charging pile is connected with the vehicle through a CAN (controller area network) line (S +/S-), the microprocessor is connected into the charging pile and the CAN line between the vehicles in a mode of inserting nodes into a communication network of the CAN line, the vehicle and the charging pile CAN receive temperature information sent out by the adapter in real time, when the temperature is too high, the charging pile and the electric automobile CAN take measures in time, and therefore the charging safety is guaranteed. Simultaneously, microprocessor carries out information interaction with filling between electric pile, the vehicle, is convenient for in time inform electric automobile or fill the condition of generating heat of electric pile adapter to vehicle and the stake of filling that use the adapter carry out effectual protection, can not make it to charge to produce overheated and the potential safety hazard that can't monitor owing to increasing the adapter.
