MC4 connector is a single contact electrical connector. They are usually used to connect solar wires to solar panels. MC4 stands for "multi contact, 4 mm". It is the standard of renewable energy industry. MC4 connector can easily build panel strings. In today's solar market, MC4 connectors and their compatible products are widely used. In most cases, larger solar panels are already equipped with M...

Copper foil soft connection: The copper foil braided busbar expansion joint is made of oxygen-free copper tube, which is flat and bright. Copper foil flexible connection products are widely used in electric vehicles, high and low voltage electrical appliances, vacuum electronics, high and low voltage switch cabinets, electric welding machines, automobiles, electric locomotives, electric furnaces, ...

Busbar is an important component in the new energy distribution system.     Busbar is a multi-layer composite connecting bus, also known as a composite bus, which can be regarded as a distribution system highway. Compared with traditional, bulky, time-consuming and troublesome wiring methods, Busbar has the advantages of easy design, low impedance, anti-interference, good reliability, sp...

SATA stands for Serial ATA. It is a type of computer bus that is mainly used for data transfer between the motherboard and mass storage devices such as hard disks and optical disk drives. This is a new type of hard disk interface completely different from serial PATAs, so named because of the serial mode of data transmission. SATA bus uses embedded clock signal, which has stronger error correction...

Background  There are still many phenomena in China's industrial chain, such as low production concentration, low R&D capability of high-end products and low manufacturing technology level of soft connection industry. The next few years will be a period of high-speed shock in the soft connection industry. The direct consequence of such high-speed shock is the expansion of polarization tre...

1. The voltage environment used is different. Eur-gauge power cords are used at 220V, while American gauge power cable usually work at 110V. 2. The core section of the US standard power cord is thicker than that of the European standard power cord. According to P=UI(P is the power, U is the voltage, and I is the current), the current passing through is higher because the working vol...

The component "BUSBAR" occupied an important position in the new energy (EV) power distribution system.   BUSBAR is a multi -layer composite structure connection row, which is also called composite parent row, which can be regarded as a highway for power distribution systems. Compared with the traditional, bulky, time -consuming, and troublesome wiring method, Busbar has the characteristics o...

The BUSBAR design selection is not only as simple as considering the ability of overcurrent. Usually when designing a battery, the most considers is busbar, paying attention to its overcurrent ability and heat.   How do we judge when doing busbar design? It is a very important point to be warming. If we simply say how wide, how many layers thick, and how much the cross -sectional area, and th...

Among the new energy vehicles (pure electric as an example) high voltage cable assemblies can be divided into 5 parts 1. Power battery high voltage cable: that is, the wiring bundle between the power battery and the high voltage box. 2. Motor controller cable: that is, the cable connecting the high voltage box to the motor controller. 3. Fast charging wire harness: connect the cable assembly ...

I. Ultrasonic welding principle: Ultrasonic wiring harness welding is a commonly used process of car wire welding. The principle is to re -combine the surface of the welding material through high frequency vibration. Ultrasonic welding energy consumption is low, no pollution, strong welding and low internal resistance, and does not change the chemical properties of welding parts. Welding cond...

What is an electrical busbar? Derived from the Latin word "omnibus", which translates as "for all" (as in "all currents in a particular system"), busbars are flat conductors that are becoming an integral part of the architecture of electric vehicles. Busbars are typically installed in switchgear, panel and busway enclosures for local high current distribution. They are also used to connect high-vo...

HV Cable selection 1. Cable diameter According to the layout diagram of each high-voltage electrical component of the vehicle, the main circuit and branch circuit are distinguished, and the responsible characteristics of the high-voltage components connected to the high-voltage wiring harness are determined. Characteristics include working voltage, rated power, peak power, rated current, peak curr...
