Technical Field
The utility model relates to an electric automobile direct current interface technical field that charges, concretely relates to electric automobile direct current charges overheated early warning safety socket of interface.
Background
At present, a temperature sensor is not arranged in a direct current charging interface of an electric automobile, and when a large current flows through the temperature sensor, the temperature sensor is used for measuring the temperature of the direct current charging interface according to a formula I2R, even a small contact resistance, can generate large power and heat due to the square of current, the socket of the current can be deformed due to mechanical expansion caused by heating by a light person, and a destructive accident can be caused by serious overheating of a heavy person, and the subsequent result is difficult to predict, so the socket has potential safety hazards.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an overheated early warning safety socket of electric automobile direct current charging interface to solve the problem that proposes in the above-mentioned background art. In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an overheated early warning safety socket of electric automobile direct current charging interface, includes socket ontology and temperature sensor, temperature sensor installs inside the socket ontology, the outer cladding heat dissipation copper sheathing of temperature sensor, the outside cladding heat conduction silicone grease of heat dissipation copper sheathing.
Preferably, the temperature sensors are two, namely a temperature sensor I and a temperature sensor II.
Preferably, the socket body is provided with a DC-port and a DC + port, the DC-port and the DC + port are output power interfaces, the temperature sensor I is arranged beside the DC-port, and the temperature sensor II is arranged beside the DC + port.
Preferably, the temperature sensor I and the temperature sensor II are internally integrated with a signal processing circuit.
The utility model discloses a technological effect and advantage: the utility model discloses do not change the inner structure of current socket, only increase temperature sensor and just can prevent to cause the overheated of socket because of reasons such as contact resistance grow, realized the settlement and the warning of temperature limit simultaneously through software, prevented that the socket that causes because of overheated warp and other damage faults, also can guarantee charging process's safety.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: the socket comprises a socket body 1, temperature sensors I and 3, temperature sensors II, 4-DC-ports and 5-DC + ports.
Detailed Description
In order to make the technical means, the creative features, the objectives and the functions of the present invention easily understood and appreciated, the present invention will be further described with reference to the specific drawings, and in the description of the present invention, unless otherwise specified or limited, the terms "mounted," connected "and" connected "should be understood broadly, and for example, the terms" fixed connection, "detachable connection," integral connection, mechanical connection, and electrical connection may be used; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
Example 1
As shown in fig. 1, the electric vehicle direct-current charging interface overheat early warning safety socket comprises a socket body 1 and temperature sensors, wherein the temperature sensors are installed inside the socket body 1, heat dissipation copper sleeves are coated outside the temperature sensors, heat conduction silicone grease is coated outside the heat dissipation copper sleeves, the heat dissipation copper sleeves and the heat conduction silicone grease can not only rapidly transmit the temperature in the socket to the temperature sensors, but also can play a role of protecting the temperature sensors, two temperature sensors are arranged, namely a temperature sensor i 2 and a temperature sensor ii 3, a DC-port 4 and a DC + port 5 are arranged on the socket body 1, the DC-port 4 and the DC + port 5 are output power interfaces, the temperature sensor i 2 is arranged beside the DC-port 4, and the temperature sensor ii 3 is arranged beside the DC + port 5, and a signal processing circuit is integrated in the temperature sensor I2 and the temperature sensor II 3, the signal processing circuit is connected with a control CPU of the charging equipment, and the low limit temperature alarm value and the high limit temperature alarm value are set through software.
The utility model discloses process flow and theory of operation do: a signal processing circuit is integrated in the temperature sensor I2 and the temperature sensor II 3, the signal processing circuit is connected with a control CPU of the charging equipment, and low-limit and high-limit temperature alarm values are set through software; when the temperature sensor I2 and the temperature sensor II 3 sense that the temperature exceeds the low limit temperature value, a low limit temperature alarm signal can be sent out to inform a control CPU of the charging equipment to properly reduce the charging current, so that the aim of reducing the temperature of the charging socket is fulfilled; if the temperature continues to rise and exceeds the dangerous warning high-limit temperature value, a dangerous alarm signal is sent out to command the charging power supply equipment to rapidly cut off the main power supply so as to ensure the safety of the charging process and the equipment. When the temperature is reduced and the safety value is recovered, the charging can be continued.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
