Electric vehicle charging pile
Electric vehicle charging pile is a pre-terminal device of charging system developed by our company for charging stations, which can realize man-machine interaction, charging, metering, charging and charge management in the charging process. It controls the charging process by exchanging information with the BMS of electric vehicles, and provides the background with video monitoring and charging status information of front-end charging process. Charging pile electric energy metering, IC card certification, cost calculation, etc. fully comply with the relevant national policies, regulations, standards and requirements.
Lead acid replacement battery can be suitable for customers who have previously used lead acid batteries, without adjusting the equipment,greatly reducing the cost for buyers. Its diverse models can meet all the needs of buyers.

Characteristics of charging pile:
■ The charging pile of EV decides charging voltage, current and charging mode according to the EV BMS information, sends the charging information to the charging power system, and monitors the whole charging process.
■ The user can operate the HD, highlight, and touch color screen through voice navigation, guide the user through the charging process, and query relevant information about the user.
■ Highly integrated charging pile:
A. It has a safe and reliable operation charge system and can identify the IC deposit cards of banks in the market.
B. Real-time video security monitoring, using the latest H.264 compression algorithm. Realize real-time video monitoring and recording of charging process and surrounding environment of charging pile.
C. Dynamic encryption network protocol is adopted to realize charging pile and power system background management network to transmit relevant information to ensure transmission reliability; communication with electric vehicle BMS is realized; industrial CANBUS is adopted to ensure transmission stability.
