Problems solved by technology

However, during use, due to the frequent on-off times of the heating relay, especially when the heating relay is switched under load, it will be impacted by the current, which will cause the heating relay to be easily damaged and shorten the life of the heating relay.
[0005] In summary, there is currently no effective solution to the problem of the short service life of the heating relay

Embodiment 1

[0046] see figure 1 , figure 2 and image 3 The method for prolonging the service life of the heating relay proposed in this embodiment specifically includes the following steps:

[0047] Step S101: When the heating film starts heating, close the heating positive relay at the first moment, and close the heating negative relay at the second moment. What needs to be explained here is that the heating positive relay and the heating negative relay are respectively connected in series at both ends of the heating film . In this way, in the process of closing the circuit, when the heating positive relay is closed, the whole circuit is still in an open circuit state, and only the heating negative relay receives the impact of current.

[0048] Step S102: When the heating film stops heating, turn off the heating positive relay at the third moment, and turn off the heating negative relay at the fourth moment. In this way, in the process of disconnecting the circuit, only the heating po...

Embodiment 2

[0063] see Figure 4 , the present embodiment provides a device for prolonging the life of the heating relay, including: when the closing module 1 is used to start heating the heating film, the heating positive relay is closed at the first moment, and the heating negative relay is closed at the second moment, wherein the heating positive relay and the heating The negative relays are respectively connected in series at both ends of the heating film, and the disconnection module 2 is used to disconnect the heating positive relay at the third moment and the heating negative relay at the fourth moment when the heating film stops heating. The times corresponding to the second moment, the third moment and the fourth moment are all different.

[0064] In addition, the device for prolonging the life of the heating relay also includes: start the heating module for the heating film to start heating when it receives the start heating signal from the battery management system, and stop th...

Abstract

The invention provides a method and device for prolonging the service life of a heating relay, and belongs to the electronic information technological field. The method for prolonging the service lifeof the heating relay includes the following steps that: when a heating film starts heating, a heating positive relay is switched on at a first moment, a heating negative relay is switched on at a second moment, and the heating positive relay and the heating negative relay are respectively connected in series at two ends of the heating film, therefore, when the heating positive relay is switched on, the heating negative relay is not switched on, that is, an entire loop is in an open-circuit state, and the heating positive relay is not affected; when the heating film stops heating, the heatingpositive relay is switched off at a third moment, the heating negative relay is switched off at the fourth moment, and the entire loop has current when the heating positive relay is switched off; no current flows through the loop when the heating negative relay is switched off, so that the heating negative relay is not affected; and time corresponding to the first moment, the second moment, the third moment and the fourth moment is different. With the above method adopted, the service life of the heating relay can be prolonged.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a method and a device for prolonging the service life of a heating relay. Background technique [0002] The relay is an electrical control device. During use, when the change of the input quantity meets the specified requirements, it can make the controlled quantity undergo a predetermined step change in the electrical output circuit. Relays are usually used in automatic control circuits. By using small currents to control large current operations to achieve "automatic switching" actions, therefore, they play the role of automatic adjustment, safety protection, and conversion circuits in the circuit. Between the input part and the output part of the relay, there is also a driving part that couples and isolates the input, performs functional processing and drives the output part. [0003] The heating principle of the electric heating film is that under the action o...
