What is the role of New Energy Vehicle Relays ?

New energy vehicle Electrical Contacts for New Energy High Voltage Relay are controlled switching devices on high-voltage circuits, and also play the role of active protection devices in the system. It has applications in each switching node of the high-voltage circuit, the main circuit of the power battery, the fast-charging circuit, and the power supply lines of high-voltage electrical appliances such as motors, DCDCs, air-conditioning compressors, heaters, etc.Like the function of general relays, Copper Contact Terminal for EV HVDC Contactor play the role of "switches" in the electrical automation industry, that is, the intermediate link that controls the on-off of one circuit to control the on-off of the next circuit. Therefore, the role of the automotive relay is to control the size and on-off of the current.


The function of the Silver Electrical Contact for EV PACK HVDC Relay is to use the switch to control the relay coil, and then the working Composite Contacts for EV Power PCB Relay is closed or disconnected. It is the large current that burns out the switch and protects the circuit and the switch.As long as you lift the hood to find the relay installation box, you can find traces of the relay. Relays are used in automotive lights, wipers, starters, air conditioners, electric seats, electric doors and windows, anti-lock brakes, suspension controls, and audio. The control relay has two main parts, one is the control system and the other is the controlled system. Controlling a large current with a small current is the characteristic of the control relay.

High Voltage DC Relay Application and Scope

1. Mainly for automobiles, solar energy, wind energy, charging piles, power storage systems, industrial automation, etc. in the new energy industry to realize power protection, automation, motion, remote control, measurement and communication.


2. Switch and protect the battery charging and discharging lines in new energy vehicles, and combine them into a safety mechanism to prevent equipment failure or short circuit, fire, etc., automatically detect and isolate faulty lines, prevent further expansion of the scope of damaged equipment, save maintenance costs, and prevent leakage. Protection, and effectively improve the battery life, the on-off control of air conditioners, steering, brakes, air pumps, motors, etc., are the core components of new energy vehicles.


3. Cooperate with the system in the charging pile to automatically charge and disconnect the charging pile, and automatically detect and protect to prevent improper operations such as overcharge, electric shock, and leakage.


4. It is used in the real-time detection system in solar power generation to assist the solar panel detection system to isolate the aging, damaged and short-circuited panels to reduce the impact on efficiency. The system remotely controls the panels for maintenance to prevent electric shock and leakage. Save maintenance costs, and prevent expansion of damage range, thereby improving the life of the power board.


5. In the power storage system, the circuit switching is realized, and the leakage detection system is constructed to prevent the impact of surge impact on the battery life, and to prevent overcharge, overdischarge and other protections.


Application of silver contacts in new energy Relays/Contactors

The Electrical Contacts for EV Charging PCB-based Relay refers to the intersection point of mutual separation and contact when the electronic appliance is disconnected and closed. Because the metal conductor terminal is prone to generate instantaneous heat and sparks at the moment of contact, it promotes its contact point in the multi-frequency process of use. , It is easy to produce oxidation and electrolysis, so the Bimetallic Contact Rivet for PCB-mounted Relays is enlarged and thickened, or it is made of polymer metal (mostly copper and silver). Or the point with the same material to increase and thicken is called silver contact.


The biggest advantage of Silver Electrical Contact for EV PACK HVDC Relay is to increase the frequency of use of the conductor, increase the contact effect, and enhance the performance of the conductor. Electrical Contacts for New Energy High Voltage Relay are widely used in the production of electronic appliances, such as switches, relays, thermostats and intersection points in conductive lines, etc., and silver riveting machines are mainly used to rive them on the terminals of various accessories.Composite Contacts for EV Power PCB Relay and other original accessories are widely used in various high and low voltage electrical appliances, electronic appliances, boat switches, power switches, relays, circuit breakers, sensors, controllers, starters, contactors and other fields.

Precautions for the use of high-voltage composite silver contacts

1. The rated values in the composite silver contact parameters are the values under resistive load. When using an inductive load with L/R>1ms, please connect a surge current protection device to the inductive load in parallel. If no measures are taken, the electrical life may be reduced, and the on-off failure may occur. Please consider sufficient margin space in the design of composite silver contacts.

2. This composite silver contact high-voltage switchgear may cause high temperature failure when it exceeds the service life and load capacity specified in this specification. A protection circuit that can cut off the load in an emergency should be used. To ensure safety, Replace parts regularly.

3. ADH series energy-saving products have a built-in energy-saving board. The coil will automatically switch after being turned on for 0.1-0.2 seconds. Repeated on-off operations of <0.2s will cause composite silver contact failures, please pay attention!

4. The Electrical contact of the ADH series product is in a sealed cavity, and the cavity is filled with gas. The leakage rate of the gas in the cavity is proportional to the temperature of the cavity (the ambient temperature and the temperature rise generated by the contact energization). Please ensure that the ambient temperature is- Within 40℃~+85.

5. Avoid using it near strong magnetic fields (around transformers and magnets) and near heating objects.

6. When installing, make sure that the main power cord is closest to the leading end of the composite silver contact, and then install it firmly in the order of flat washers, spring washers, and nuts, or use self-locking nuts directly. Incorrect connection sequence may cause severe overheating and cause the insulation of the connecting cable to melt.

7. Please control the screw tightening torque of each part within the following specified range. Exceeding the range may cause damage to the sealed cavity and thread damage. In addition, the installation direction is not restricted.
