❓ Frequently Asked Questions
Q: What type of battery chemistry does this BMS support?
A: This BMS is designed for LiFePO4 (Lithium Iron Phosphate) battery chemistry, which is known for its superior thermal stability, long cycle life, and enhanced safety compared to other lithium-ion chemistries.
Q: What is the maximum input charging current this BMS can handle?
A: The typical maximum input charging current is 80A. It is important not to exceed this value to ensure safe and reliable operation of the BMS and battery pack.
Q: What is the output discharging voltage range?
A: The output discharging voltage ranges from a minimum of 46V to a maximum of 74V, with a typical operating voltage of 64V, making it suitable for 20S LiFePO4 configurations.
Q: What does the 20S battery link configuration mean?
A: "20S" means 20 cells connected in series. For LiFePO4 cells with a nominal voltage of approximately 3.2V each, a 20S configuration yields a nominal pack voltage of around 64V, which matches the typical output discharging voltage listed.
Q: What is the continuous output discharging current limit?
A: The continuous output discharging current must be kept at ≤ 120A. Exceeding this limit may trigger the BMS protection mechanism or cause permanent damage to the battery system.
Q: What are the physical dimensions of this battery module?
A: The product dimensions are 168 × 83 mm. These compact dimensions make it suitable for integration into a variety of energy storage systems and electric vehicle battery packs.
