  • Briefly describe the types of electric vehicle charging guns
    Briefly describe the types of electric vehicle charging guns
    Jan 09, 2024
    The development of electric vehicle charging varies by region and use case. This creates a high level of complexity and a high number of part numbers for OEMs around the world. But for electric vehicle supply equipment (EVSE), including EV chargers, there are three common descriptions: mode, level, and type.   1. Pattern These modes reflect several common types of EVSE connections to the grid: (1) Mode 1 plugs into a household AC outlet but is generally not allowed in most areas due to the lack of special safety electronics. (2) Plugs into a standard household AC outlet, these safety features are included in its Cable Control Box (ICCB). (3) Plug into a wall box or charging station for AC charging. Excludes international commercial banks. In Europe, consumers usually need to bring their own Mode3 cables to use public AC charging stations. (4) The charging station retains high-speed DC charging. Good Quality Manufacturers AC240V 48A Plug Wallbox Ev Charging Station   2. Level The rating represents the amount of electricity delivered to the vehicle. In the J1772 standard, the Society of Automotive Engineers specifies the following levels: Level 1: Limited to 120V and 1.8kW, and provides basic charging. Fast Charging AC Type1 Plug Electric Car Charge Cable EV Charging Station   Level 2: Defined as 208V to 240V, maximum 80A, maximum output power 19.2kW. As battery sizes increase, OEMs are also increasing power levels in the range. Today, a typical pure electric vehicle can obtain 11kW of AC power from an onboard charger. Homes installed with three-phase power can achieve 11kW at 16A, while single-phase power needs to provide around 48A.   DC Level 1 and 2 provide fast charging and are only available at commercial charging stations. DCLevel2, often referred to as Level3, can provide up to 1000VDC and is expected to reach 500A in the future, with an output power exceeding 350kW. This speed can charge a typical electric car battery to about 80% in 20 minutes. European Standard Type 2 Ev Charger Gun For Electric Vehicle Charging   3. Type Type refers to the vehicle interface. Unfortunately, standards organizations do not support global standards. Therefore, three unique AC charging interfaces have SEDeared in the world: Type J17721 AC and Type CCS1 DC are used in North America and Korea. IECType2 is used for European alternating current, and CCS2 is used for direct current. J1772Type1 Japan is for AC power and CHAdeMO is for DC power. The GB/T interface is a unique DC interface in my country's AC. In addition, China and Japan may adopt new superpolar standards.

  • Detailed introduction to new energy charging gun standards
    Detailed introduction to new energy charging gun standards
    Jan 02, 2024
    Let’s introduce the standards for car charging gun specifications.   Let me first put a very intuitive picture. First of all, charging guns are divided into DC guns and AC guns, which in English are AC (Alternating Current) and DC (Direct Current). DC guns are high-current, high-power charging guns, which are generally equipped in fast charging stations for new energy vehicles. Those used at home are generally AC charging piles or portable charging guns.   1. AC charger There are three main types, type1, type2 and GB/T, which can also be called American standard, European standard and national standard. Of course, Tesla has its own standard charging interface, but due to pressure, Tesla has also begun to change its standards according to market conditions to make its cars more suitable for the market. Just like domestic Teslas must be equipped with national standard charging mouth. European Standard Electric Vehicle Charging Gun   ①Type1: SAE J1772 interface, also known as J-plug   Basically, the United States and countries that have a closer relationship with the United States (such as Japan and South Korea) use Type 1 American standard charging guns, including portable charging guns carried by AC charging piles and cars. Therefore, in order to adapt to this standard charging interface, Tesla also has to provide a charging gun adapter so that Tesla vehicles can use public charging piles with Type 1 charging ports. 7KW On-board Charging Portable EV Charger   Type1 provides two main charging voltages: 120V (Level1) and 240V (Level2).   ②Type2: IEC 62196 interface   Type2 is the new energy vehicle interface standard in Europe, and the rated voltage is generally 230V. The picture may look a bit like the national standard, but it is actually easy to tell the difference. The European standard is similar to the engraving, and the black part is hollow, which is the opposite of the national standard.   2. DC charging gun 3.5KW Charging Cable Level 2 Portable EV Charger   DC charging guns generally correspond to AC charging guns. Each region has its own standards, with the exception of Japan. Japan’s DC charging port is CHAdeMO. Of course, not all Japanese cars use this DC charging port. Only some Mitsubishi and Nissan’s new energy models use the following CHAdeMO DC charging port. Japanese DC charging port   Others are American standard Type1 corresponding to CCS1: mainly adding a pair of high-current charging holes below. American standard DC charging port   European standard Type2 corresponds to CCS2: European standard DC charging port   Naturally, we also have our own DC charging standard: national standard DC charging port   The rated voltage of DC charging piles is generally above 400V and the current reaches several hundred amps, so they are generally not for household use and can only be used at fast charging stations in shopping malls, gas stations and the like.

  • SED Connectors – Decoding the Essentials
    SED Connectors – Decoding the Essentials
    Jan 06, 2024
    SED Connectors, commonly known as SED plugs, have their roots in Europe and America. In the logistics and communication industries, these rectangular plugs, also referred to as SEDconnectors, play a crucial role in high-current equipment, UPS power supplies, 5G power systems, medical devices, AC/DC power supplies, and various other SEDlications. They facilitate the machine connection for power, signal, and data transmission.   Amidst the plethora of SED cable assemblies available in the market, how do we discern and select the right one that meets the standards of quality and performance? 50a 600V SED Connector   **1. Material Matters:** Understanding the composition of SED cable assemblies is fundamental. Currently, three main materials dominate the market: silver-plated copper, nickel-plated copper, and nickel-plated brass. The distinction between copper and brass lies in copper's superior conductivity and malleability, making it less prone to breakage during crimping. SED cable assemblies produced by DMIC employ copper with a silver-plated layer, boasting minimal impurities and higher purity. The silver layer enhances conductivity, effectively lowering resistance and improving overall conductivity.   Fast Power Products battery SED plug connector   **2. Application-Specific Selection:**   SED connectors come in varying pole numbers, ranging from single-pole to three-pole configurations. These cable assemblies find SEDlications in high-current scenarios such as UPS power supplies, chargers/stations, cleaning equipment, lithium batteries, AGV smart trucks, and more. Choosing the SEDropriate plug type depends on the specific usage scenario, allowing users to tailor their selection based on location and intended SEDlication. Forklift Battery Connector Plug SED Connector   **3. Impact of End Quenching Process:**   The termination process significantly influences the quality of cable assemblies. Some unscrupulous vendors produce cable assemblies with non-quenched terminals, resulting in excessive hardness that makes them prone to breakage during crimping. Conversely, poor quenching can lead to issues such as problematic crimping or excessively soft terminals that deform easily during usage – clear signs of subpar products.   In conclusion, it is imperative to choose products with guaranteed quality. Manufacturers like DMIC, specializing in SED cable assemblies, adhere to strict production standards, holding multiple certifications. These are trustworthy products, ensuring reliability and performance that meet and exceed industry standards. Choose wisely for peace of mind and optimal performance.

  • Why do connectors need to be tested for insertion and extraction force?
    Why do connectors need to be tested for insertion and extraction force?
    Dec 23, 2023
    Connectors are also called connectors. Also called connectors and sockets in China. They generally refer to electrical connectors, which are devices that connect two active devices and transmit current or signals. When the male and female ends come into contact, messages or current can be transmitted. In order to ensure the reliability and stability of the connector after adaptation, this standard is specially formulated according to EIA-364-13C (International Electrotechnical Association plug-in and pull-out force test specifications), which stipulates that the plug-in and pull-out force shall not be greater than the rated value (to ensure that users will not have difficulty inserting adapter), the pull-out force must not be less than the rated value (to prevent loosening or falling under various complex situations, causing interruption and damage to the device connection). Terminal riveting standards compiled and released   Test insertion and extraction force procedures Insertion and extraction force test   Test Purpose: To test the force required when inserting and extracting each terminal using a standard test male plug to evaluate the quality characteristics of the terminal and confirm that the force generated by the connector during use is sufficient to maintain the connector's functionality and suitability for consumption.   Testing basis: EIA-364-13 or MIL-STD-1344A, 2013.1.   Testing equipment: Pullout force testing machine High-Performance Battery Plug 50A   Test Methods: 1. The size and surface roughness of the connector PIN or BLADE used for testing comply with the requirements of MIL-3197.   2. The PIN pin or BLADE of the test connector should be cleaned regularly to prevent its surface from being covered with film and affecting the accuracy of the measurement data. SGX Forklift Battery Connector Plug SED Connector   3. Test step 1 (using connector PIN or BLADE):   A. Plug and unplug once to adjust the terminal status.   B. Insert the largest size test connector PIN or BLADE while measuring the insertion force. Pull out the test connector PIN or BLADE and replace it with the smallest size test connector.   Precautions: SG 50A T-handle vehicle power plug   Test insertion and extraction force. Since ALIGNMENT has a great influence on the accuracy of the test, special attention should be paid to the consistency of the LOAD CELL of the slave machine, the test PIN and the center line of the test sample during the test.   Test points:   1. The test object is the entire connector and complete components.   2. The test axis is the direction of normal use of the connector.   3. Unless otherwise specified, the test speed is defined as 25.4 mm/min.   Require:   1. The insertion force is generally set to the maximum value. (Maximum 35N).   2. The extraction force is generally set to the minimum value. (7N Min.initial; 3N Min.Final), some customers also require setting the maximum value.   The insertion force is the force generated when two matching connectors are completely separated from each other to the working state; the extraction force is the force generated by the two matching connectors from the working state to being completely separated. Insertion and extraction force is generated when consumers use the product. The insertion and extraction force is only generated when there is a docking end (io/plug, jack/plug).

  • What is the difference between lithium batteries and lead-acid batteries for electric forklifts?
    What is the difference between lithium batteries and lead-acid batteries for electric forklifts?
    Dec 01, 2023
    As my country's forklift industry continues to grow beyond expectations, various products and domestic and foreign markets have achieved excellent performance. Among them, the proportion of electric forklifts has steadily increased. At the same time, in the face of the increasingly severe energy situation and environmental protection pressure, as well as the opportunities brought by external conditions such as the development of new energy vehicles and the increasingly mature lithium battery technology, lithium battery forklifts are ushering in development opportunities. in a huge market opportunity. So what is the difference between lithium batteries and lead-acid batteries for electric forklifts? Which one is better? Features are as follows:   1. Compared with large batteries such as lead-acid and nickel-cadmium, lithium-ion batteries do not contain cadmium, lead, mercury and other environmentally polluting elements and are pollution-free. When charging, there will be no "hydrogen evolution" phenomenon similar to lead-acid batteries, and it will not corrode wire terminals and battery boxes. It is environmentally friendly and reliable. Lithium iron phosphate batteries have a lifespan of 5 to 10 years, no memory effect, and no need for frequent replacement;   2. The same port and SED plug(Rema High-current battery connector,Forklift Battery Cable Connectors,Original Forklift Battery Connector) are used for charging and discharging, which solves the major safety problem of the forklift being unable to operate when charging due to different charging ports; 3. The lithium-ion battery pack is equipped with an intelligent lithium battery management and protection circuit - BMS, which can effectively and automatically cut off the main circuit in response to low battery power, short circuit, overcharge, high temperature and other faults, and can perform sound (buzzer) and light (display) ) alarm, traditional lead-acid batteries do not have the above functions;   4. Triple safety protection. We use intelligent monitoring and protection devices placed between the batteries, the battery's internal total output, and the bus's total output, which can monitor the battery in real time and cut off protection in special circumstances.   5. Lithium-ion batteries can be used as one of many materials and devices to be integrated into the huge Internet of Things system. It can promptly notify whether the battery needs maintenance or replacement, and automatically count the time of entering the factory, the number of charges and discharges, etc.; 6. For special industries, such as airports, large warehousing and logistics centers, etc., lithium-ion batteries can be charged in "fast charging mode", that is, the battery can be fully charged in 1 to 2 hours during the lunch break to keep forklifts running. The vehicle works continuously when fully loaded;   7. Maintenance-free and automatically rechargeable. After the lithium-ion battery is self-packaged, it does not require any special water injection, regular discharge, etc. Its unique constant-time active balancing technology greatly reduces the workload of on-site personnel and saves huge labor costs;   In fact, until now, lead-acid batteries have remained the first choice in the intralogistics industry due to their low procurement costs. However, continued improvements in lithium-ion batteries and associated reductions in production costs are causing industry professionals to rethink. More and more customers rely on forklifts equipped with this advanced technology to handle their intralogistics tasks.
