In the past year, the market of photovoltaic inverter mainly consists of centralized inverter and series inverter, and the proportion of micro-inverter and distributed inverter is small. With the rapid development of distributed photovoltaic market, the proportion of series inverters in centralized photovoltaic power stations is increasing, and in 2018, the market of series inverters accounts for 60.4%. In addition, it is worth noting that the distributed photovoltaic inverter improves the MPPT control effect compared with t...

The battery management system (BMS) is like the heart of a new energy vehicle, and many new energy vehicles lack the competitive power often reflected in the defects of the battery management system. For many new energy vehicle brands, it is very difficult to develop a battery management system. Because the battery management system contains many resistive components, such as precision resistors, shunts, capacitors, transistors, and so on. These products need professional brand suppliers, and technology is also critical. At p...

With the development of the electric vehicle, the charging pile of the electric vehicle has started to be extended and applied. For electric vehicles, the battery management system detects the battery through the precision shunt, and will prompt the owner to charge the charging pile when the battery is found to be insufficient. The frequent problem of charging piles is the phenomenon of electric leakage, which is very unsafe for both the charging pile and the electric vehicle. In order to provide better safety, the charging p...

A car grade resistor is an important electronic component of automobile electronic products. For many automotive resistors, it can be entered into the automobile market only when it meets the requirements of automobile electronics. Many automobile manufacturers have very strict requirements for resistors because this small resistor may affect the safety of the entire car. Car gauge resistors usually need to be certified by AEC-Q100 standard. The AEC-Q100 standard is designed to prevent possible situations or potential failur...

The shunt resistor is widely used in the digital watt-hour meter, high-precision test instrument, and all instruments and meters for measuring, sampling and shunting current, and can also be used as the main component of the current sensor. At present, the traditional shunt resistor is low in precision, and the temperature coefficient is high. It is difficult to meet the higher requirements, and many resistance manufacturers have started to develop new shunt resistors. The shunt resistor comprises a resistor composed of a co...

Electric vehicle battery is the main power source of new energy vehicle. The high precision shunt in battery management system will indicate that the battery is insufficient. Replacing batteries has become the preferred choice for many consumers when it is no longer possible to drive a car for a long time, which will lead to a large amount of battery power. How to make use of these batteries has become a topic for many battery manufacturers. In the current technology, the reuse of residual batteries can effectively reduce th...

Precision current shunt is a kind of common resistor, which has been widely applied to household appliances. Precision current shunt has a wide variety of types and different models. They can be seen in many products. This resistor is widely used in both DC circuit boards and AC circuits, and can accurately test current size. In the precision current shunt, there are five very stable precision resistors ( 0.001, 0.01, 0.1, 1 and 10 ), which can be used to measure AC and DC currents from 0.02A to 220A. The principle of AC / D...

Metal strip chip resistors are the first choice in many circuit design applied surface mount resistors. Because of its particularity, alloy chip resistance can be widely used in many products, especially in the circuit design of electronic products. It is often used to detect voltage or current size. Resistance manufacturers usually use rectangular metal composite strips to make alloy chip resistors, which are safe and convenient for production and transportation. In the current sampling scheme, the current value can be fed ...
