EU Standard DC EV Charger mainly relies on the following aspects to reduce energy loss during charging:
1. Charging efficiency optimization technology
Based on power transmission directional design technology:
Intelligent power transmission, through which power transmission is oriented, to prevent the waste of useless power, thereby improving charging efficiency.
This helps to ensure that during the charging process, the electric energy is more efficiently transmitted to the battery of the electric vehicle, reducing the energy loss during the transmission process.
Based on battery optimization design technology:
The research and development and application of new battery materials, such as ternary lithium batteries, can achieve high energy density and high charging efficiency with relatively light battery weight.
The optimized battery can better match the charger and reduce energy loss during charging.
2. Improvement of charging method
Reasonable choice of DC fast charging and AC slow charging: Although DC fast charging has a fast charging speed, long-term use may have a certain impact on battery life. Therefore, when possible, choosing AC slow charging can help reduce energy loss during charging.
Avoid fully charging and discharging the battery: When charging the battery of an electric vehicle, avoid charging it to 100% or discharging it to 0%, which can effectively reduce the increase in the internal resistance of the battery, thereby reducing the energy loss during the charging process.
3. Consistency of charging protocol and communication protocol
ISO/IEC 15118 standard: The intelligent charging communication technology introduced by this standard can realize the intelligent interconnection between the vehicle and the charging pile, optimize the communication efficiency during the charging process, and reduce energy waste.
4. Application of intelligent charging technology
Intelligent charging pile and on-board charging system: With the development of intelligent network connection technology, intelligent charging piles and on-board charging systems can automatically adjust charging parameters, charge in the most optimized way, and further reduce energy loss.
In summary, EU Standard DC EV Charger can effectively reduce energy loss during charging and improve charging efficiency through charging efficiency optimization technology, charging method improvement, consistency of charging protocol and communication protocol, and application of intelligent charging technology.
