The function of charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging ev. Charging pile generally provide conventional charging and fast charging two kinds of charging ways, people can use certain recharge CARDS in charging pile to provide credit card using the human-computer interaction interface, accordingly the charging ways, charging time and cost of operation, such as variable data printing, charging pile screen can show charging quantity, cost, such as charging time data.

As the energy source of many products, the power supply is an indispensable part, and many low-power power supplies are well known to everyone (such as adapters). However, high-power power supplies, including 100W to 100KW and above UPS, inverters, high-power emergency equipment, photovoltaic inverters, etc., are designed with a combination of multiple topologies, requiring test and certification engineers to have strong circuit understanding capabilities. In order to evaluate the safety and rationality of the product, and the impact of abnormal test current is large, if you do not understand the product, it will easily cause harm to the power grid, engineers, and the environment. Therefore, many third-party laboratories and institutions do not have the capacity and conditions to certify this part of the product. Our company has been engaged in certification services in this field for a long time, has accumulated rich experience, and configured corresponding equipment and testing envir
