The current sense resistors have medium and bigger resistance. They are used in various power products, power equipment, charging piles, feedback circuits, measuring instruments and so on because of its high precision, low resistance , high shock resistance ability and low TCR. The resistors used for current sense need small resistance, this is very different from the ones used for voltage detection. Usually, the sampling resistor is in series in the circuit to detect the current. Therefore, it is widely used In current detection, resistance is usually used to detect, and this resistance value should be very small, unlike voltage detection need resistance value can be a little larger, usually the sample resistance is in series in the circuit to detect the current.
 

 

The current detection resistors are widely used in new energy automobile, wind power generation, solar photovoltaic power generation and the charging pile and play very important roles in these devices. In the following, we sort out the application of the current sense resistors.
 
Firstly,  the current detection resistance is used in the real-time detection system of solar power generation, and associated with solar panel detection system to isolate the panel aged, damaged or shorted out so as to reduce the impact effect. System remote control battery board for maintenance, anti-electric shock, leakage, maintenance costs reduce, and anti-expansion of damage range so as to improving the life of the power panel.
 
Secondly, current sampling resistors, cooperating with the system, charge transmission and disconnection automatically, perform automatic detection and protection, prevent improper operations , such as overcharge, electric shock and leakage and more.
 
Thirdly, current sampling resistors is mainly applied to automobile, solar energy, wind energy, charging pile, storage system, industrial automation to realize electric protection, automation, movement, remote control, measurement and communication.
 
Fourthly, in the power storage system, it helps the circuit switch realized, the leakage detection system constructed, protect anti-surge impact on battery life, overcharge and overdischarge.

 

 

All types of current detection resistors can be found in the need of new energy products. The use of current sense resistors is of great significance in improving the performance of products. New energy industry is one of the industries with high growth rate and use most current sense resistors.
