Types of high-voltage electricity for new energy vehicles

Public Announcement on Proposed Identification of Jiangxi Provincial Enterprise Technology Center in 2023 (26th Batch)

Recently, the Provincial Department of Industry and Information Technology announced the list of Jiangxi Provincial Enterprise Technology Center to be identified in 2023 (the 26th batch). Five enterprises, including Blue Core Storage Technology (Ganzhou) Co., Ltd., Ganzhou Xinguan Technology Co., Ltd., Ganzhou Good Friends Technology Co., Ltd., Jiangxi Shanxiang Pharmaceutical Co., Ltd., and Ganzhou Ruifut Technology Co., Ltd., were successfully selected, ranking first in the city.

New Energy Power Battery Details-Lithium Battery

Power battery industry chain: divided into battery materials, power batteries and systems two parts, according to Ping An Securities estimates, battery materials market size of more than 600 billion, power batteries and systems more than 520 billion.

Types of high-voltage electricity for new energy vehicles

According to the national standard GB/T 18384.3-2015 "Safety Requirements for Electric Vehicles Part 3: Protection against Electric Shock", considering the humidity of the air and the resistance of the human body in different working environments, the vehicle voltage is divided into two safety levels according to the type and value of the vehicle voltage in new energy vehicles according to the different levels of injury and danger to the human body.

Selection of high-speed connectors

With the rapid development of electronic communication technology, integrated circuit packaging and board interconnection, the bandwidth of signal transmission requirements are getting higher and higher. At the same time, the transmission rate of the interconnection channel is getting faster and faster, and the decision time window of the logic gate is getting smaller and smaller. As a result, the development of information technology has led directly to the development of integrated circuit packages, transmission lines, and connections in interconnect channels, from the beginning of the "lumped parameter model" to the "distributed parameter model". Compared with the package of the integrated circuit, the transmission line and the connector on the printed circuit board are more likely to enter the "distributed parameter model", that is, the high-speed signal interconnection channel, due to the relatively large geometric size. PCB interconnection lines, connectors and components arranged on the electronic equipment constitute the main components of the interconnection system, the signal through the printed board interconnection lines and connectors extended to other printed boards, thus constituting the entire transmission system. As the key part of the whole interconnection system, the connector has become the bottleneck to improve the transmission rate of the system. Therefore, the development of the connector to meet the high-speed transmission performance is the main means to improve the high-speed interconnection performance of the system, and it is also the key factor to solve the problem of high-speed interconnection of information system.

Common Audio Communication Terminals

Audio communication terminal is the most widely used type of communication terminal in the communication system. It can be an ordinary analog telephone, a recording telephone, a coin telephone, a magnetic card telephone, an IC card telephone applied to the ordinary telephone exchange network PSTN, a digital telephone applied to the ISDN network, and a wireless mobile phone applied to the mobile communication network. In addition, a computer with audio processing capability can also perform the function of an audio communication terminal with the support of software.

Come and see! Ganzhou Economic Development Zone Awards 2022 "Top Ten Ecological Demonstration Enterprises!

In order to thoroughly implement Xi Jinping's thoughts on ecological civilization, comprehensively promote the green and low-carbon transformation, establish a group of ecological environmental protection demonstration enterprises that adhere to "ecological priority, green and low-carbon", play a leading role in demonstration, and improve the green and low-carbon development level of enterprises in the region, In November 2022, Ganzhou Economic Development Zone launched the 2022 "Top Ten Ecological Demonstration Enterprises" selection work for ecological environmental protection in the region, after enterprise registration, qualification review, online voting, expert review, soliciting opinions from various units, online publicity and other links, the "Top Ten Ecological Demonstration Enterprises" were finally selected ". At the 2022 work summary commendation and 2023 work mobilization meeting of Ganzhou Economic Development Zone, representatives of 10 enterprises rated as "top ten ecological demonstration enterprises" came to the stage to receive the commendation.
