The formulation and goals of green energy policies drive the transformation of electric transportation, the rapid rise of the electric vehicle market, and the successive exposure and listing of electric vehicles of various brands, which will enter the era of electric vehicles running all over the street. It also affects the research and development of charging pile products and the deployment of charging sites. Whether it is DC fast charging, AC slow charging, or supporting different charging specifications and different powers, charging pile products have sprung up everywhere, providing charging services to solve electric problems. Owner’s mileage anxiety.

However, both electric vehicles and charging piles are surrounded by electricity, and their safety and functionality need to be strictly verified to ensure safe use. Each vehicle adopts different charging specifications such as CCS1, CCS2 and different communication protocols DIN and ISO. With different languages, the smooth communication between the car and the pile will also affect the charging process. In order to ensure smooth communication between different charging piles and vehicles of various brands and the safety of the charging process, the Bureau of Standards, Inspection and Quarantine of the Ministry of Economic Affairs has formulated the relevant standards of “CNS15511 Conductive Charging System for Electric Vehicles” to ensure that the quality and safety meet the basic requirements.

Status and difficulties encountered in electric vehicle charging test

For the charging of electric vehicles, traditional tests will encounter some obstacles. In addition to the time-consuming and inconsistent test accuracy, the following problems will also be encountered due to the product characteristics of electric vehicles and charging piles:

  • Wide range of output power of charging piles: Unlike gas stations, charging piles can be built in a variety of parking areas – residential, commercial buildings or public parking lots. AC and DC charging piles ranging from 7kW to over 350kW provide different fields domain application. A wide range of output power challenges the ability of product verification testing.
  • Multilingual communication protocol: how to communicate with the charging pile equipment for electric vehicles of various depots that speak different languages ​​for charging services. For example, in the language proficiency test, it is necessary to meet the communication ability test of different language families to ensure the smooth progress of charging.
  • Dynamically evolving global regulations: In the past decade, electric vehicles have developed rapidly, and electric vehicles and charging equipment have been evolving, and global regulations must be optimized and updated accordingly. The test system needs to be able to keep up with the pace of regulatory changes and to update the verification regulations in real time.

In order to meet the requirements of the verification policy, Taiwan’s benchmark verification agency, the Taiwan Power Research and Test Center, introduced Delta’s automated test system to prepare the communication protocol for electric vehicles and charging piles to verify the capacity.

Delta’s automated test system is subordinate to the communication protocol testing requirements ahead of time

Delta has built an automated test system with years of experience in R&D and manufacturing of electronics and charging piles for electric vehicles. The purpose of system development is to solve the traditional testing pain points: time-consuming, insufficient testing coverage, testing items that cannot keep up with the speed of regulatory changes, etc., and greatly improve testing efficiency and accuracy with automated testing.

Delta’s automated test system has built-in Delta’s Smart 1 test software platform, and uses the OEM-approved Vector VT system to write communication protocol test items*. The system integrates the Vector VT system on Delta’s Smart 1 test platform, transforming it into an electric vehicle and testing the charging pile equipment to be tested; or playing the role of a charging pile to communicate and charge with various electric vehicles. Simulate the real charging situation, verify the hand-holding ability between the electric vehicle and the charging pile, and accurately test the compatibility and interoperability between the two. Delta’s test system uses a fill-in-the-blank operation to test on demand, reducing the learning curve and speeding up the test process. The system supports communication protocol testing of mainstream American, European and Japanese electric vehicles and low-power AC charging piles to a maximum of 360kW DC charging piles, which can be accurately verified and tested regardless of the vehicle or the pile.

Delta’s automated test system adopts an open architecture, which can flexibly configure the optimal equipment combination according to actual test requirements and maintain the possibility of expansion. The built-in test program can be updated and updated with the evolution of global regulations, in preparation for the expected evolution of electric vehicle or charging station equipment.

The era of electric vehicles is coming, and electric vehicles can travel between cities without any obstructions, and the charging piles all over the place can be used to stop and replenish electricity at any time. In order to ensure the safety and high efficiency of charging electricity, the verification of electric vehicle charging is imperative. Delta’s automated test system is currently also introduced by the Taiwan Power Research and Test Center to assist in the verification and testing of electric vehicles and charging pile products.
