Problems solved by technology

However, this control mode has a disadvantage. When the contact of the temperature control switch is stuck, the high voltage cannot be cut off, which will cause the PTC heater to work all the time, which may damage the PTC heater and vehicle components, or cause damage to the car. spontaneous combustion

Embodiment Construction

[0009] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0010] Such as figure 1 A PTC heater protection device for a new energy vehicle is shown, including a power battery 1, a high-voltage distribution unit 2, a control module 3 and a PTC heating module 4. The high-voltage distribution unit 2 is connected to the power battery 4. The PTC heating module 4 includes a temperature control switch 141, a temperature control switch 242 and a heating component 43. The temperature control switch 141 and the temperature control switch 242 are connected in parallel in the circuit. Through this structural setting, the double protection device of the PTC heater of the new energy vehicle solves the technical proble...

Abstract

The invention relates to a new energy automobile PTC heater protection device which comprises a power battery, a high-voltage distribution unit, a control module and a PTC heating module. The PTC heating module is in signal connection with the control module through a loop, the PTC heating module is connected with the power battery through the high-voltage distribution unit, and the PTC heating module comprises a temperature control switch 1, a temperature control switch 2 and a heating part. And the temperature control switch 1 and the temperature control switch 2 are connected in parallel in a loop. Through the structural arrangement, the dual protection device for the PTC heater of the new energy automobile solves the technical problems in the control mode of the existing PTC heater, and powerfully guarantees the safety of the automobile and the personal safety.

Description

technical field [0001] The invention relates to the technical field of heaters, in particular to a PTC heater protection device for new energy vehicles. Background technique [0002] New energy vehicles are clean energy vehicles and have been vigorously developed. Because the new energy vehicle cancels the traditional engine, the PTC heating system of the whole vehicle is newly developed to meet the needs of heating the cab and passenger compartment, defrosting and defogging the whole vehicle. The existing PTC heater generally uses a temperature control switch in series in the low-voltage control circuit. When the temperature reaches the preset temperature, the normally closed contact of the temperature control switch is disconnected, the low-voltage circuit is disconnected, and then the high-voltage output circuit is disconnected. control mode. However, this control mode has a disadvantage. When the contact of the temperature control switch is adhered, the high voltage ca...
