钠离子电池是否需要保护板？

What is the core advantage positioning of Sodium-ion Battery?    

钠离子电池必须搭配保护板（BMS电池管理系统）使用，缺一不可，无保护板的钠电池严禁直接投入使用。保护板的核心作用是全方位守护电池安全和使用寿命，能够实时精准监测电池单体及电池包的电压、电流、温度、压差等核心数据，智能管控充放电过程。在出现过充、过放、过流、短路、高温、单体压差过大等异常情况时，保护板会自动切断电路，规避热失控、鼓包、短路、烧毁等风险，同时通过均衡功能修正单体电量差异，提升电池包整体一致性和循环寿命，是钠电池安全稳定运行的核心保障。

The core industrial positioning of Sodium-ion Battery is a low-cost, safe, resource-unconstrained and inclusive new energy battery, focusing on the two core tracks of large-scale energy storage and low-speed civil power, forming an accurate complement with lithium batteries. Its core advantages are concentrated in five dimensions: first, resource advantage, sodium resources are abundant in the earth's crust and evenly distributed around the world, without mineral monopoly and resource bottleneck risk; second, cost advantage, raw materials are cheap, and current collector uses general aluminum foil, so the overall production cost is much lower than that of lithium batteries; third, safety advantage, stable physical and chemical properties, extremely low thermal runaway risk, and excellent safety under extreme working conditions; fourth, environmental adaptation advantage, outstanding low temperature performance, and stable operation in both high and low temperature environments; fifth, life advantage, cycle life is much longer than that of traditional lead-acid batteries, which can meet the needs of long-term commercial use, and is a cost-effective inclusive energy storage and power battery.
