Abstract

The utility model discloses a special-purpose power socket for charging batteries of an electric vehicle, which comprises a socket main body [13] and a temperature measuring component [20], wherein the temperature measuring component is connected with the socket main body in series through a wire [10], wherein a temperature relay [3] is arranged in the temperature measuring component and is fixed at the bottom, a normally open switch [4] which is arranged on the temperature measuring component is connected with a double-throw switch [22] arranged on the socket main body in parallel through the wire [10], and the switch temperature can be set through a temperature control push button which rotates on the temperature measuring component. In addition, two magnets [1],[11] are further arranged in the temperature measuring component, which are fixed on two sides of the box body, and are convenient for adsorbing the temperature measuring component on the surface of a battery when in charging. When a battery of an electric vehicle is charged, the temperature measuring component senses the temperature on the surface of the battery through an internal temperature sensor. The special-purpose power socket can effectively prolong the service span thereof through guaranteeing the surface temperature without exceeding a preset value when the battery of an electric vehicle is charged.

Description

Charging battery of electric vehicle power source special socket

Technical field

The utility model relates to a kind of supply socket, particularly relates to a kind of charging battery of electric vehicle power source special socket.

Background technology

Battery of electric vehicle generally all has been equipped with special charger, but the useful life of battery is still shorter.Except the self reason of battery, charger, during charging battery temperature too high also be the major reason of shorter battery life, particularly useful life at the battery more than a year, its heat generation characteristic is more obvious.During battery charge, battery temperature too high meeting causing battery outward appearance distortion, even battery explosion at this moment, if reach a certain limiting temperature at battery temperature, are promptly cut off the electricity supply, and stop charging, though charging less than, can effectively protect battery, prolong its useful life.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, esy to use, safe and reliable and cheap charging battery of electric vehicle power source special socket, work as battery temperature during charging and surpass design temperature, temperature relay will automatic disconnection charger power supply, prolongs its useful life.

For achieving the above object, the utility model comprises: the lead 10 of socket main body 13, temperature measurement unit 20 and gang socket main body and temperature measurement unit.One end of socket main body is installed the jack 7,12 that links to each other with lead 8, and lead 8 passes sidewall aperture 14 and connects attaching plug 9; The other end is installed jack 5,6, is used for connecting the plug 23 of charger.Temperature measurement unit is that the casing 2 of material is formed by a jack 24, temperature relay 3, two blocks of

magnet

1,11 with plastics.Temperature relay 3 is close to the bottom of casing 2 and is fixed, so that the better temperature of perception battery, it is in parallel that its normal open switch 4 and commutator 22 on the socket main body pass through lead, and two blocks of

magnet

1,11 are separately fixed at the inner surface of casing 2 both sides; Lead 10 1 ends connect jack 24, and the other end is connected on the jack 19 on the socket main body by plug 21, makes temperature relay 3, switch 22 connect with the jack 6,7 of socket main body respectively.During charging battery of electric vehicle, temperature measurement unit is adsorbed on the battery surface optional position, by the temperature of temperature inside sensor senses battery, and automatic disconnection charging circuit when temperature reaches 50 ℃ of temperature that relay sets, unless press switch 22 once more, otherwise will no longer be battery charge.Beneficial effect

During charging battery of electric vehicle, when temperature surpasses the temperature of relay setting, cut off the power supply automatically, prevent that the temperature of battery is too high, prolong its life-span.

The purpose of this utility model, feature and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.

Embodiment

Among Fig. 1,1, magnet, 2, the temperature measurement unit casing, 3, temperature relay, 4, the normal open switch of temperature relay, 5, jack, 6, jack, 7, jack, 8, lead, 9, plug, 10, lead, 11, magnet, 12, jack, 13, socket main body, 14, the sidewall aperture, 15, sidewall, 16, diapire, 17, rear wall, 18, roof, 19 roof jacks, 20, temperature measurement unit, 21, plug, 22, commutator, 23, Charger (portable round), 24, jack.

Fig. 2 is a schematic diagram of the present utility model.Before the charger charging, earlier temperature measurement unit is adsorbed on the battery surface, after the energized, press commutator SB, then relay coil obtains operating voltage, the K1 closure.Though after this SB disconnects, the K1 closure make relay still electric working on, make power output socket XS that electricity be arranged, Charger (portable round) was inserted in and can begins on the socket XS to charge the battery this moment.During charging, if the battery surface temperature is lower than 50 ℃ of the temperature that temperature relay sets, charger normally is a battery charge; When the battery surface temperature was elevated to 50 ℃, temperature relay started, and K1 disconnects, and power output socket XS does not have electricity, charger and power-circuit breaking, unless press switch S B once more, otherwise will no longer be battery charge.Thereby the battery surface temperature is not higher than 50 ℃ when guaranteeing to charge, and reduces the chance of battery distortion, and then prolongs its life-span.
