From August 26 to August 28, the 14th Shanghai International Electric Vehicle Supply Equipment Fair (EVSE) was held at the Shanghai New International Expo Center. TÜV Rheinland, an internationally independent third-party testing, inspection and certification organization, attended with a comprehensive display of its professional and one-stop service capability covering the upstream and downstream segments of the industry chain.

With the rapid implementation of the “New Infrastructure” strategy, the local subsidy for purchasing new energy vehicles is being gradually transferred to such segments as the construction and operation of charging infrastructure and the use and operation of new energy vehicles. In addition, electrification of buses and taxis, electrification of logistics transportation, and the increasing demand for charging services in the timeshare rental market will further promote the flourishing of the charging pile market.

The only company to win Golden Pile Award 2020 Excellent Brand of Testing and Certification Service for Charging Facility

On the morning of August 26, the Golden Pile Award 2020 Top 10 Charging Facility Brands Awarding Ceremony was held. The Golden Pile Award is an annual event recognizing development achievements in China’s charging technology. It aims to encourage outstanding enterprises to enhance technology innovation and improve product quality and service level, so as to promote the construction and development of China’s charging infrastructure. With leading technology and quality service in the testing and certification of charging equipment, TÜV Rheinland was awarded the 2020 Excellent Brand of Testing and Certification Service for Charging Facility, and is the only testing and certification organization to have won the award.

As a global leading technology service provider, TÜV Rheinland has rich experience of nearly 10 years in the field of charging and swapping systems. It can provide product testing and certification for charging piles, charging stations, pantographs, swapping stations, charging cables, charging connectors, and related parts. It can also provide audits and technology assessments for charging and swapping systems and provide automobile companies and charging operation service providers with comprehensive localization services, including charging pile installer training, operator qualification audits, and field installation audits.

During the EVSE, TÜV Rheinland issued corresponding product certificates to more than ten charging equipment enterprises, and signed cooperation agreements with numerous companies, comprehensively demonstrating its technology advantage and service capability covering the entire industry chain.

Safety assessment regulations project for HPC equipment liquid cooling systems launched

For a long time, range and charging time have been two key factors restricting the development of new energy vehicles. With range now increasing, battery capacity needs to be increased accordingly, and charging time will also become longer. In order to make new energy vehicles more practical and convenient, high power charging (HPC) is an effective way to reduce charging time, but this also puts the charging system at risk of overheating. Therefore, a liquid cooling system has been adopted for HPC products, with a special circulation channel set in the cable and charging connector and liquid coolant added in. A power pump pushes the liquid circulation and achieves heat dissipation, and simultaneously cools the charging connector and the direct current pin in the vehicle inlet. Built-in temperature sensors measure system temperature in real time. By evaluating the temperature-rise data, a control unit can effect timely adjustment of the operating parameters of the liquid cooling system, thereby solving the heat dissipation problem and ensuring the safe and stable operation of the charging system.

At the EVSE, TÜV Rheinland and 20 upstream and downstream companies focused on HPC technology gathered to launch a safety assessment regulations project for HPC equipment liquid cooling systems, giving full play to their respective advantages and joining hands to promote the establishment of system safety assessment regulations. The 20 companies are as follows: ABB Chargedot, Aptiv, Amphenol (Zhuhai), OMG, Haoli Technology, Jiangyin Zhongding, Kangni New Energy, Kunshan Hwatek, Phoenix (Nanjing), Shanghai Huber+Suhner, Wanbang (Star Charge), Wuxi Xinhongye, EN-plus, EAST, Infypower, Far East Cable, Uchen New Energy, UUGreenPower, Zhengqi Machinery, and JONHON.
