FAQ

Q1. How do we maintain rigorous control over battery safety and quality?

Safety Testing Protocols are critical to our battery quality assurance, involving rigorous tests under extreme conditions including overcharging, overdischarging, short circuit, needle puncture, and high temperatures (up to 85ºC storage).
Capacity Verification Test: Through charge and discharge cycles, we ensure actual capacity aligns with nominal values, guaranteeing reliability.
Cycle Life Evaluation: Retains ≥ 80% capacity even after 2000 cycles, ensuring long-term durability.
Certified by CE, UL, RoHS, TUV, MSDS, UN38.3, based on the ISO9001 management framework.

Q2. How do we ensure optimal performance of battery groups?
Initial Consistency Screening is conducted to maintain uniformity before grouping batteries.
We eliminate cells with notable discrepancies in voltage, internal resistance, and capacity, ensuring pairing within ±1% using capacitive devices for precision.
Employing Dynamic Voltage Adjustment (DVA) for precise matching of individual cells within battery packs.

Q3: How can we extend battery life through strategic measures and maintenance?

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

1. Enhance charge and discharge management
-Protect your battery by avoiding deep discharges. For instance, it's recommended to maintain lithium-ion battery levels between 20% and 80% to ensure optimal performance.
-Utilize an advanced intelligent BMS (Battery Management System) to precisely regulate the charging cutoff voltage, keeping ternary lithium batteries at or below 4.2V per single cell.
-Safeguard your battery's health by avoiding charging under extreme temperatures. Refrain from charging at temperatures exceeding 45ºC or below 0ºC.
2. Temperature management
-Incorporate an efficient heat dissipation system, such as air or liquid cooling, to maintain the battery's operating temperature between a safe range of 15 to 35ºC.
-Prevent overheating by avoiding prolonged high-rate discharges, for example, discharges greater than 1C.
3. Regular battery maintenance and monitoring
-Ensure balanced charging by having your BMS regularly calibrate any differences in individual cell voltages through passive or active balancing.
-For long-term storage, it's advisable to keep the battery charged at 50% and recharge every three months to maintain peak condition.
-Monitor the battery for signs of aging. Consider replacing it when capacity degrades by more than 20% or when the internal resistance increases by over 30%.
