As the penetration rate of new energy vehicles continues to soar, fast charging stations, as the core hub of the energy replenishment network, are experiencing explosive growth. However, at the same time, the safety hazards of DC fast charging systems have gradually become prominent, both positive and negative*The characteristic of ungrounded (IT distribution system) makes the decrease in insulation resistance a key risk point for equipment failure and electric shock accidents.

How to accurately monitor insulation status and provide early warning of safety hazards? Ankerui AIM-D500-CA DC system insulation monitoring instrument provides professional answers. As the backup "insulation guardian" of fast charging stations,cooperate, coordinate, collaborateACPD300The coupling instrument for insulation monitoring can monitor up to1000VIt is more compatible with the two major fast charging standards of CCS and CHAdeMO, providing all-weather and high-precision insulation safety protection for fast charging stations in different regions around the world.

1、 Directly addressing industry pain points

1.Potential risks brought by system characteristics: DC systems in fast charging stations often adopt ungrounded designs, with positive and negative terminals*Once the ground insulation resistance falls below the safety threshold, it may cause equipment insulation breakdown, large leakage current, and even lead to electric shock accidents for personnel;

2.Complex working conditions exacerbate hidden dangers: frequent start stop operations during fast charging, changes in high and low temperature environments, cable aging and wear, and other factors can accelerate the deterioration of insulation performance. If not detected in a timely manner,*Easy to cause equipment failure or safety accidents;

3.Mandatory requirements for standard compliance: Both the CCS charging standards in Europe and America, as well as the CHAdeMO standards in Japan, have clear requirements for insulation monitoring of DC systems. Compliance monitoring is a fundamental prerequisite for the operation of fast charging stations.

However, traditional insulation monitoring methods suffer from slow response, low accuracy, and poor adaptability, making it difficult to meet the high-frequency and high reliability monitoring needs of fast charging stations.

II Analysis of Core Advantages

1. Dual standard full coverage, suitable for global fast charging scenarios

As a professional equipment for the international market, AIM-D500-CA is deeply compatible with two mainstream fast charging standards:

CCS standard: widely used in fast charging systems for electric vehicles in European and American countries, it is one of the mainstream fast charging protocols worldwide. AIM-D500-CA can seamlessly integrate various fast charging devices under this standard;

CHAdeMO standard: mainly used for fast charging interfaces of electric vehicles in Japan and some overseas markets. The equipment meets the strict insulation performance requirements of this standard through precise monitoring algorithms.

Whether it is an export-oriented fast charging station for the European and American markets or an energy replenishment network serving diverse domestic vehicle models, AIM-D500-CA can be easily adapted without the need for additional equipment replacement, significantly reducing station construction costs and operational complexity.

2. Wide range+precise monitoring, early detection and disposal of hidden dangers

The core performance advantages of the product are highlighted, providing full protection for fast charging stations:

Ultra wide voltage coverage: By default, it supports monitoring of 50-400V DC systems. When paired with ACPD300 insulation monitoring coupling device, the range can be extended to 1000V,Covering the voltage requirements of mainstream fast charging stations;

Signal injection method technology: Adopting advanced signal injection monitoring methods in the industry, it is not affected by DC system ripple and harmonic interference, and has higher accuracy in measuring insulation resistance, which can accurately capture subtle changes in insulation performance;

Intelligent warning and alarm: real-time online monitoring of positive and negative signals*When the value of ground insulation resistance is lower than the safety threshold set by the user, an audible and visual warning or alarm signal will be immediately issued, and remote linkage will be supported to facilitate quick response and disposal by operation and maintenance personnel, avoiding the expansion of hidden dangers.

3. Multi scenario adaptation, not limited to fast charging stations

In addition to the core electric vehicle charging device, AIM-D500-CA can also be widely used in scenarios such as power generation manufacturers, DC screens in substations, UPS power supply systems, and various industrial DC power grids, with*Strong universality. For enterprises that simultaneously deploy DC power supply projects in multiple fields, the unified use of AIM-D500-CA can achieve standardized equipment management and improve operation and maintenance efficiency.
