As a high-voltage and high-power device, charging piles have safety risks throughout their life cycle, including the risk of electric shock caused by leakage and insulation failure, and the risk of short circuit or fire due to insufficient voltage resistance.
Difficulties of Testing
Multiple Items to Test
The basic safety test items for charging piles include withstand voltage, insulation, grounding, and leakage. However, due to the testing requirements for input and output ends, AC piles and DC piles, and high-power dynamic leakage, more test items are extended.
Tough Test Conditions
The testing requirements range from single-phase 20kW to three-phase 90kW, and the equipment compatibility requirements are high;
It is necessary to simulate extreme working conditions such as 1.1 times the rated voltage and multiple fault modes.
Low Data Tracing Efficiency
Test data needs to be connected to the MES system to achieve full process traceability;
Manual recording is inefficient and prone to errors.
Advantages of Ainuo Solution
In response to above difficulties, Ainuo launched the charging pile safety test solution AN1651TH-60(F)CP, with "full-scenario coverage, intelligent operation, and high-precision verification" as the core, to help companies pass certification efficiently.
Cover Full Test Range of Charging Pile
Ainuo 1651TH-60(F)CP supports 9 major test items including power input/output voltage withstand, insulation, ground resistance, etc.
1. AC withstand voltage and insulation resistance test of charging pile power input;
2. AC withstand voltage and insulation resistance test of charging pile AC output;
3. DC withstand voltage and insulation resistance test of charging pile DC output;
4. Withstand voltage and insulation test between charging pile power input, AC output and DC output;
5. Grounding test between charging pile power input, AC output, DC output and shell;
6. Dynamic leakage current test of charging pile input. For those within 90kW, load leakage current test can be performed. For ultra-high power, leakage meter test can be used.
7. The comprehensive electrical safety tester can provide input power specifications for charging piles, single-phase 20kW, three-phase 60kW, 90kW; external power supply for higher power.
8. The charging pile input is powered by a single-phase or three-phase feedback RGL AC variable frequency power supply, which meets the feedback load test of 60kW-1000kW (tested under full load condition of 1.1 times rated voltage), compliance test, and energy saving.
9. Special test switching device, optional barcode gun, ESRS system, support MES connection.
Conclusion
Driven by tightening policies and market expansion, charging pile companies can only remain invincible in the fierce competition by relying on advanced technology and strict standards. Ainuo AN1651TH-60 (F) three-phase electrical safety tester provides all-round support for enterprises with full project coverage, intelligent ecosystem and extreme verification capabilities.
