A Discussion on the Requirements of Electric Vehicle OBC and the Applicable Standards
1.Abstract The OBC (On-Board Charger) is one of the interface components of an EV (Electric Vehicle). It must interact with the external environment through connections to the public power grid or dedicated electric vehicle supply equipment. These devices are interfaced with the AC power grid, and their ratings and requirements are beyond the control of […]
IEC 60947-2 Feasibility Analysis of Standard Certification for Residual Current Protection in Electric Vehicle Chargers
1.Abstract The European region has high requirements for the standards and certification of electric vehicle charging piles. This article explores how to meet these standards to reduce design complexity and cost from the perspective of different leakage current standards in the European Standard IEC. By providing a detailed interpretation of mechanical coupling, electronic coupling, leakage current […]
A brief discussion on the topology structures of energy storage converters (PCS) and current detection.
1.Development Trends of Energy Storage Converters (PCS) To achieve peak carbon emissions by 2030 and carbon neutrality by 2060, new power generation forms are continuously increasing their share of installed capacity in the power market. As of 2022, China’s wind and photovoltaic generation reached 1.19 trillion kWh—an increase of 207.3 billion kWh over 2021, up 21% year‑on‑year—accounting for 13.8% […]
A Discussion on Leakage Insulation Detection Methods in DC Insulation Systems
1.Background The new round of the Israel-Palestine conflict has lasted for over a week, pushing international crude oil prices into an upward trend. On the 13th of October, New York oil prices saw a significant rise, with November delivery of New York light crude oil futures increasing by $4.78, closing at $87.69 per barrel. The […]
