China's top ten charging pile companies

Which of the top ten charging pile companies in China is better? Which company is better for charging piles? How to choose a charging pile enterprise? The top 10 charging pile companies Shenzhen Hongjiali New Energy Co., Ltd. owns its own factory, providing one-stop exclusive services, focusing on the research and development, production, sales and installation, operation and management of automobile charging piles, and has a number of self-developed core technology patents, professional R&D team, 1000+ site building case experience, support oem customization.

As a kind of green transportation with broad development prospects, electric vehicles will be popularized very rapidly in the future, and the future market prospects will also be extremely huge. In the context of the global energy crisis and the serious environmental crisis, the Chinese government is actively promoting the application and development of new energy vehicles. As an important supporting infrastructure necessary for the development of electric vehicles, the Chinese government has very important social and economic benefits. .

The overall system consists of four parts: Electric Vehicle Charging Pile, concentrator, battery management system (BMS), and charging management service platform.

The control circuit of the electric vehicle charging pile is mainly completed by the embedded ARM processor. The user can self-swipe the card for user authentication, balance inquiry, billing inquiry and other functions. It can also provide a voice output interface to realize voice interaction. The user can choose 4 charging modes according to the instructions of the LCD display: including charging on time, charging according to power, automatic charging, charging according to mileage, etc.

The electric vehicle charger controller and the concentrator use CAN bus for data interaction, and the concentrator and server platform use wired Internet or wireless GPRS network for data interaction. For safety, the power billing and amount data are encrypted.

The main function of the battery management system (BMS) is to monitor the working status of the battery (the voltage, current and temperature of the battery), predict the battery capacity (SOC) of the power battery and the corresponding remaining mileage, and perform battery management to avoid over-discharge , Overcharge, overheating and serious voltage imbalance between single cells, maximize the use of battery storage capacity and cycle life.

The charging service management platform has three main functions: charging management, charging operation, and comprehensive query. Charging management centrally manages the basic data involved in the system, such as electric vehicle information, battery information, user card information, and charging pile information; charging operation mainly performs charging management for user charging; comprehensive query refers to management and operation data Perform comprehensive analysis and query.
