Securities Star News: According to data from Qichacha, CATL (300750) has obtained a new invention patent authorization titled "Testing System, Method, Electronic Equipment, and Storage Medium for Power Supply Conversion Device". The patent application number is CN202110877278.7, and the authorization date is April 9, 2024.
Patent Abstract
The present embodiment provides a testing system, method, and storage medium for a power conversion device, belonging to the field of aging testing technology. The power grid is connected to the AC end of the first power conversion device, and the power grid is also connected to the AC end of the second power conversion device. The DC end of the first power conversion device is connected to the DC end of the second power conversion device, so that a testing circuit can be formed between the power grid, the first power conversion device, and the second power conversion device. In this testing circuit, the first power conversion device and the second power conversion device can both act as loads and power sources, so there is no need to equip additional DC power supplies and loads during testing, saving investment costs and energy consumption. The control unit can control the first power conversion device and the second power conversion device to work simultaneously in different working modes, so aging tests can be conducted on both the first power conversion device and the second power conversion device simultaneously, improving testing efficiency.
