FAQ

Q1. How do we ensure stringent control over battery safety and quality?

Safety Testing is a critical component of our battery quality assurance program, encompassing extreme condition tests such as overcharging, overdischarging, short circuits, needle puncture, and high-temperature storage at 85ºC.
Capacity Test: We verify that the actual battery capacity aligns with the nominal value through rigorous charge and discharge cycles.
Cycle Life Test: Our batteries maintain ≥ 80% capacity even after 2000 cycles.
Certified to meet CE, UL, RoHS, TUV, MSDS, and UN38.3 standards under the ISO9001 management system.

Q2. What is the optimal way to maintain peak performance in battery groups?
Consistency Screening is performed as a preliminary step before batteries are grouped.
- We eliminate cells showing significant variances in voltage, internal resistance, and capacity (such as pairing within ± 1%) using capacitive devices.
- Implementing Dynamic Voltage Adjustment (DVA) to harmonize individual cells within the battery pack.

of batteries exported to over 90 countries worldwide.

Q3: How can we extend the lifespan of our batteries through proper measures and maintenance?

Q4: What are your strengths, export experience, and both domestic and international use cases?

1. Optimize charge and discharge management
-To ensure the longevity and efficiency of your battery, it's crucial to avoid deep discharges. For lithium-ion batteries, it's recommended to maintain a power range of 20% to 80%.
-Implement an intelligent Battery Management System (BMS) to precisely control the charging cutoff voltage. For instance, ensure that a ternary lithium battery does not exceed 4.2V per single cell.
-Always avoid charging your batteries in extreme temperatures. Charging should not occur at high temperatures exceeding 45ºC or low temperatures below 0ºC.
2. Temperature control
-To maintain optimal battery health, install a heat dissipation system, such as air cooling or liquid cooling, to keep the operating temperature between 15 and 35ºC.
-Prevent any excessive heating that could result from prolonged high-rate discharges, which are typically greater than 1C.
3. Regular maintenance and monitoring
-Engage in balanced charging: Utilize your BMS to regularly calibrate voltage differences among individual cells, employing either passive or active balancing techniques.
-For optimal battery storage, maintain 50% power when the battery is not in use for extended periods. Recharge the battery every three months to preserve its integrity.
-Carefully monitor for signs of aging. Consider replacing the battery if you observe a capacity drop greater than 20% or an internal resistance increase exceeding 30%.
