What are the frequent problems with relays and Auto Relay in use?
The range of use of relays is now more and more extensive, the more frequently used,the longer the time, there will be some problems, then on relays and automatic relays The more common problems are as follows:
The contact of the relay is faulty, which is more common. For most faults, about 70% of the faults occur on the contacts. It is important to select all the relay contacts.
First, the choice of AC and DC electromagnetic relays Almost all AC relays are caused by the humming caused by the armature vibration. When the voltage on the relay coil (or current) When the specified action value is not reached, the armature flutter will cause the contact to shake. If the contact is connected to the inrush current load, the arc caused by the chatter may be touched.
The point is melted or welded. Second, the relay operating voltage selection When the relay works, the coil should apply the rated
working voltage (current) instead of the suction voltage (current), thus enabling The electrical coil voltage (or current) has a mechanical voltage shock or ambient temperature rise when the power supply voltage (or current) fluctuates or the relay is used. The insurance margin of work. The suction voltage (or current) is only a parameter that the manufacturer limits the sensitivity of the relay and evaluates it.
The relay has different release voltages The bigger the better. When the relay is released, if the leakage current in the coil circuit is too large, the relay will not be released reliably. Third, the selection of relay load capacity and failure analysis relays will be the following kinds of loads when in use
1, capacitive load
The charging current of the capacitive circuit, the short-circuit discharge current starts at a large time,when charging or short-circuiting, the contact may be severely ablated due to too much charging current or Welding failure. In use, if the current limiting capacity can be connected in series according to the size of the capacitance,the hazard can be eliminated.
2, incandescent lamp load
Since the cold resistance of the tungsten wire in the incandescent lamp is very small, the inrush current at the instant of turn-on is as high as 15 times the steady-state current. Such a large inrush current will make the contact quickly. Corrosion, even welding failure.
3, motor load
The input impedance is very small when the motor is stationary, so the surge current is very large just after starting.
Due to the difference in motor load, its startup time has It can be short or long, so the startup surge current lasts for the same amount of time. In addition, the relay contact is used as the motor opening and closing switch, and the shutdown is continued. The electrical appliance must withstand the arcing caused by the high induced back voltage shock of the motor windings, so the insulation resistance level between the contact groups and the ability to withstand overload must be There
is ample surplus.

Europe automotive relay market is expected to grow at a CAGR of 7.4% during the forecast period, 2018-2023, owing to increasing penetration of electronic systems in vehicles.
With growing technology in semiconductors, heavy electromagnetic relays have been gradually replaced by the solid state relays, as solid state relays showed high potential in handling or switching power from low to high or vice-verse modes efficiently in the automotive electric circuits. Though solid state relays are expensive than electromagnetic relays, the former relays are anticipated to gradually gain more demand from automakers. Also, increasing incorporation of vehicle features like heated seats/power seats, power windows, windshield wiper/washer systems, sunroof etc., have resulted in more demand for automotive relays.
Increase in Electric Vehicle SalesThe incentives offered by the EU government for purchasing electric vehicles (EV) has significantly boosted the EV sales in the region during 2015-2017. The growing electric vehicle sales have been significantly driving the need for electric contact components like relays and switches, especially in battery electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV). In addition, with the enactment of stringent emission norms in the EU region automakers are gradually shifting their production from internal combustion engine vehicles to electric vehicles. As a result, the region is anticipated to experience more demand for and usage in relays, owing to the growing EV demand and sales during the forecast period.
Growing Competition among ManufacturersThe major automotive relay manufacturers in the region include Panasonic Corporation, Omron, Fujitsu, TE connectivity etc., are consistently working to improve relay design and functionality. Currently, solid state relay has become the major focus for most of the manufacturers due to its higher operating benefits compared to the present technology (miniature of the electromagnetic relay). Thus, the manufacturers are looking forward to producing more solid state relays by adopting cost-effective production methods to reduce the high cost of solid state relay in the coming years. The local manufacturers such as Eberspacher also started manufacturing solid state relay for automotive applications to capture the growing demand for electric vehicles. Thus, the region is expected to experience high competition among international and local manufacturers, with their improved and reduced price of solid state relay product offerings.
