As an energy-saving and environmentally-friendly vehicle, electric vehicles are also national key support projects, but they have been delayed in popularity. The fundamental reason is that charging is difficult. The AC charging pile is the main force of the charging network and is small in size. It is suitable for public places such as residential areas, parking lots, streets, units, commercial buildings, office buildings, shopping centers, etc. However, at present, the number of charging piles in China is very small, and there is a lack of mandatory standard constraints, and the quality is uneven, which is difficult to meet market demand.


     In order to solve the charging problem, Shenzhen Vilva Electronics Co., Ltd. has helped the electric vehicle to popularize and use its years of accumulated research and development experience to produce high-quality electric vehicle AC charging piles. This charging pile has four technologies in the same industry. Advantage.


      Charging is the basic function of electric vehicle charging pile.Vilva AC charging pile has strong adaptability. It supports both mainstream lithium, iron lithium and lead acid batteries, and is also compatible with old nickel-metal hydride and nickel-cadmium batteries. In the absence of mandatory standards in the industry, Weirwa AC charging piles support GB/T 18487.1-2001 and NB/T 33002-2010 standards, providing standardized power interfaces, plug-and-charge, easy to use. The charging efficiency is high, and the battery can be cured according to the intelligent matching charging mode of the peak-to-valley time.


      In terms of human-computer interaction, Vilva AC charging pile uses a bilingual interface, full touch operation, charging can be achieved with a single click, and charging time and cost limit can be set. The user can use the IC card and the RFID card to consume, and the charging pile automatically reads out the battery information contained in the card to optimize the charging process. The Wilhelm payment system is securely encrypted, and the user can directly manage the account on the charging pile screen to understand the expenditure, balance, electricity price and other information, and clearly understand the consumption.


      In terms of communication, the Vilva AC charging pile is connected to the vehicle-mounted charger through the CAN bus, and communicates with the battery management system BMS of the battery, and uses Wilhelm's exclusive sulfur removal maintenance patent and online technology to intelligently detect the health status of the battery pack. Suppresses vulcanization and maintains battery capacity. The AC charging pile also realizes real-time networking and information sharing of the battery, the payment card, the charging pile and the monitoring center through power carrier communication or using GPS, GPRS/CDMA wireless modules.


      In terms of workmanship, Vilva AC charging piles meet military-grade standards, high temperature resistance and good insulation. With security module and camera, it can be self-illuminated at night, and there is no dead angle. It is also equipped with an anti-collision and anti-theft monitoring sensor to protect itself when it encounters a collision. Welch's charging piles have three appearances: standard floor-standing, space-saving wall-mounted and more affinitive cartoons that serve different venues.


      Vilva has nearly 20 years of R&D and production experience in the field of intelligent battery charge, discharge and detection. The company has passed ISO9001 international quality system certification, double soft certification of the Ministry of Information Industry and Guangdong high-tech enterprise certification. Weirwa has customized a series of charging and testing equipment for electric vehicles. Weirhua AC charging piles, DC charging piles, charging stations, vehicle-mounted chargers, and charging equipment intelligent test loads are all recommended products in China's power industry. Japan, South Korea, the United Kingdom, Australia, Singapore, Thailand and other countries. Among them, the intelligent charging and discharging detection system for electric vehicle batteries also won the special prize of China Patent High-tech Products Expo.
