- Introduction
Analysis of the core content of the standard
Technical dimensions 2012 version New additions/changes in the 2021 version Charging method Conductive charging only New wireless charging (static/dynamic) and 4 charging modes Equipment type Basic charging equipment Added 12 new types of equipment, including AC/DC integrated machines, mobile equipment, and automatic charging couplers Battery swapping technology General terms Details 5 types of battery replacement positions (side/bottom/top, etc.) and 8 types of special equipment
Evolution of key technologies
1. Wireless charging system architecture
The standard clearly defines the MF-WPT magnetic coupling wireless charging technology system for the first time, including:
- Ground equipment: primary equipment (transmitter) + power transmission controller (PTC)
- On-board equipment: secondary equipment (receiver) + power receiving controller (PPC)
- Key parameters: working air gap (7-25cm) and ground clearance requirements
2. V2X two-way interactive system
Build 5 application scenarios of electric vehicles as distributed energy storage units:
Mode Connected object Typical application V2G Public power grid Peak shaving V2B Commercial buildings Demand management V2V Other vehicles Emergency power supply
Implementation suggestions
1. Equipment selection guide
Select the type of charging equipment according to the application scenario:
- Public fast charging stations: Prioritize constant power chargers (efficiency＞95%)
- Bus hubs: Recommend top contact charging system (charging pantograph + receiving bus)
- Residential areas: Configure ordered charging control unit (can reduce distribution capacity by 30%)
2. Key points of battery swap station construction
Key configurations:
- battery box locking mechanism (mechanical strength ≥2000N)
- vehicle guidance system (positioning accuracy ±2cm)
- Battery health detection module (SOC error <3%)
