1 The charging pile is divided into single phase and three phases. Whether it is dual phase or single phase, it must first be converted to the amount of AC incoming current. 1 For single-phase charging pile, AC charging pile I=PU 2 For three-phase charging pile, DC charging pile I=PU*1732 After calculating the current in this way, select the cable according to the current. 2 Cable selection can be related manuals or procedures such as 1 Single-phase charging pile is generally 7KW AC charging pile IObc manufacturers; led by BYD GeelyObc manufacturersFor example, the latest new energy models of self-owned brandsObc manufacturersThe external discharge power of its flagship model has reached more than 6kW. The Lynx 09 EMP Voyage version can support up to 64kW. The AC charging port adopts a two-way OBC design #160 Ideal new models L7L 8L9 have come standard with 35kW external discharge and 220V socket in the car. However, the Tesla Model Y, which is known as a "camping artifact", is due to the use of a lower-cost one-way OBC; On Geely's new energy models mass-produced between 2016 and 2019, they are equipped with "2-in-1" high-voltage re-discharge system assemblies PDU+OBC with different technical states, and "2-in-1" control modules integrated with the drive motor controller and OBC. At the same time, the "3-in-1" high-voltage charging and discharging system has been replaced. The structure of the complete electric drive and high-voltage charging and discharging control system of the "3-in-1" electric drive assembly has been reduced to the greatest extent. To two parts; There are domestic manufacturers that manufacture ECUs. The so-called ECU of Shanghai United Automotive Electronics Co., Ltd., that is, Electronic Control Unit, also known as "driving computer" and "vehicle-mounted computer". In terms of purpose, they are vehicle-specific microcomputer controllers, also called vehicle-specific single-chip processors. In the early 1990s, the concept of intelligent transportation systems, or ITS, was proposed abroad. Intelligent Vehicle IV is an important component of intelligent transportation systems; Infineon has an application note that introduces the basic idea of PC life calculation. Calculation is based on PC curves and junction temperature fluctuation cycles. The result curves obtained by different PC test methods may be different, and the test methods of different manufacturers have different vehicle sizes. The reliability standards of the block are unified. Test conditions, fair comparison of PC capabilities of different devices, device failure probabilities are different, and PC curves are also different. Basic OBC applications are closely related to PFC topologies. Vehicle OBC is complex; At present, there are various thermal conductive silicone manufacturers on the market, and there are more and more manufacturers and agents. The following are the important well-known brand manufacturers of thermal conductive silicone tablets. The domestic brand Taiwan Pioneer thermal conductive silicone tablets is produced in China and accounts for a large share among Taiwanese companies. The thermal conductive silicone tape is of good quality, complete product series, and low thermal conductivity. AOK brand Aochuan Technology is an early merchant in the market in China and accounts for a certain market share in China.
Shanghai Shark Sporting Goods Co., Ltd. is a professional sporting goods manufacturer founded under the macro guidance of Shanghai Oriental Basketball Club, referred to as OBC, with OBC as the leading image. It is said that such a relationship is said to have no future for this brand; Karaoke "usually plays the lyrics with beat prompts simultaneously on the TV screen while playing a pre-recorded musical accompaniment stored on a medium such as a video tape, and then the participants watch the lyrics while holding a microphone to sing.""Karaoke" is an accompaniment system in which singers can participate in singing under the pre-recorded musical accompaniment."Karaoke" can beautify and polish the singer's voice through sound processing. Zhonghui Chuangzhi's magnetic resonance wireless power supply technology and kitchen appliance wireless power supply technology solutions. The main products are various power wireless power supply ICs and modules.

What is the three-in-one new energy vehicle three-in-one refers to the design that integrates three important units: the vehicle ACDC power charger OBC vehicle DCDC power converter DC and the vehicle high-voltage connection hub PDU. In most vehicle models, these three components are separate independent units. As new energy vehicles have become the focus of research and development of many car companies, the demand for related parts and components continues to increase. New energy; As Huawei's first electric drive system DriveONE, the system directly integrates seven major components: MCU microcontroller unit motor reducer DCDC DC converter OBC vehicle charger PDU power distribution unit and BCU battery control unit, realizing mechanical components and power components. Deep integration and Huawei is preparing to bring intelligence into the electric drive system to realize end-cloud collaboration and control integration. 1 Huawei DriveONE Electric; Although it simply seems that it just increases the voltage platform, it is not easy to achieve this goal. The difficulty lies in that all high-voltage components, including DCDCOBC motor controllers, motors, air conditioners, compressors, PTC high-voltage contactors, high-voltage insurance, etc., are all above 600V, and this can only be achieved by companies like BYD that have R & D advantages in the entire industry chain, because all parts involved must have unified standards, such as electricity for high-voltage parts.
In the field of analog chips, in the past, international manufacturers such as Texas Instruments, TI, Adno Semiconductor, ADI, Infineon, almost monopolized. Now, in some categories, domestic manufacturers can compete with international manufacturers in terms of technical indicators, performance and price. For example, Nanochip Micro Shengbang Micro Ai is an electronics company and other companies. Among them, Shengbang Micro mainly focuses on the consumer market. Nanochip Micro smelled the opportunities in the new energy vehicle market earlier and laid out the automotive industry. In 2016, it released the first automotive-grade chip as the domestic largest; 8 Sanan Group was established in November 2000. Its main products are 650V05um GaNSi and 200V100V05um GaNSi. Its gallium nitride EHEMT technology serves consumer and industrial applications, such as adapter chargers, telecom servers, SMP wireless power car chargers, OBC and cost-effective solutions. 9 Suzhou Jiexinwei was established in 2013, its main products are silicon-based gallium nitride power electronic devices; As the first digital isolator manufacturer in China, Rongpai Semiconductor Shanghai Co., Ltd. has always adhered to the front line of R & D. In 2022, Rongpai Semiconductor's performance showed continued and steady growth, achieving an eye-catching result of a year-on-year increase in revenue of 110%. Facing the severe challenges of the international environment With the continued spread of the epidemic and downward pressure on the economy, how did Rongpai Semiconductor achieve growth against the trend? Through an exclusive interview with Rongpai Semiconductor Vice President of Sales Hu Yongjun and Dong Shuangbing, Technical Director.
