Congratulations PVSYS Energy had passed the LifePO4 battery test of IEC62619 and PVSYS battery is trsutworthy in the market.
Most customers do not know well about IEC62619 test for LifePO4 battery. Why it is very important? We will explain details as below.
IEC 62619 is an international safety standard developed by the International Electrotechnical Commission (IEC) for industrial lithium-ion batteries and battery systems, particularly those used in energy storage applications. It focuses on long-term safety and reliability under high-capacity conditions. Below are the core test items included in the standard, along with brief explanations.
1. Electrical Safety Tests
Overcharge Test
Simulates battery failure due to excessive charging (e.g., BMS ). The battery must not catch fire or explode.
Test condition: Charged at 1C or manufacturer-specified current up to 1.5x rated voltage or higher.
Overdischarge Test
Evaluates safety risks (e.g., copper dendrite formation) when the battery is discharged beyond safe limits.
Test condition: Discharged to 0V or lower, checked for leakage or structural damage.
External Short-Circuit Test
Simulates a direct short between positive and negative terminals (e.g., installation error). The battery must control temperature rise and avoid thermal runaway.
Test condition: Fully charged battery shorted with ≤5mΩ resistance; temperature and fire risk monitored.
Thermal Abuse Test
Assesses stability under extreme heat.
Test condition: Battery placed in a 130°C chamber for a set duration (e.g., 1 hour); must not explode or ignite.
2. Mechanical Safety Tests
Vibration Test
Simulates mechanical vibrations during transport or operation. The battery must maintain structural integrity without electrolyte leakage.
Test condition: Random vibration per IEC 60068-2-64 (5Hz–500Hz frequency range).
Mechanical Shock Test
Evaluates resistance to sudden impacts (e.g., drops, collisions).
Test condition: Half-sine wave shock at ≥15g acceleration, tested in multiple directions.
Crush Test
Simulates external force compression (e.g., improper installation) to prevent internal short circuits and thermal runaway.
Test condition: Apply 13kN pressure until 15% deformation or voltage drops to 0V.
3. Environmental Safety Tests
High-Temperature Storage Test
Assesses performance degradation and safety after prolonged exposure to high temperatures.
Test condition: Stored at ≥60°C for 7 days, then checked for capacity retention and physical damage.
Temperature Cycling Test
Evaluates battery endurance under extreme temperature fluctuations.
Test condition: Cycled between -20°C and +60°C multiple times (e.g., 5 cycles), with dwell time at each extreme.
4. Functional Safety Tests (BMS-Related)
Protection Circuit Test
Verifies BMS effectiveness in preventing overcharge, overdischarge, overcurrent, and overheating.
Test method: Trigger fault conditions artificially; BMS must cut off power as required.
Insulation Resistance Test
Ensures electrical isolation between the battery system and its casing to prevent leakage currents.
Test condition: Apply 500V DC; insulation resistance must be ≥100Ω/V (e.g., ≥100kΩ for a 1000V system).
