Can Sodium-ion Battery be used for construction machinery?    

钠离子电池非常适合轻型电动工程机械、电动叉车、小型农机等工程设备场景，是工程设备电动化的核心电源选型。工程设备对电池的核心要求是大倍率放电、动力强劲、耐造耐用、抗震动、高低温适配、成本低。钠电池具备优异的大倍率充放电性能，可实现瞬时大功率输出，满足工程机械的动力需求；结构稳定性强，抗震动、抗冲击，可适配工程设备的复杂作业工况；耐高低温性能优异，可在户外严寒、酷暑环境下稳定工作；同时成本远低于锂电，循环寿命长，可大幅降低工程设备的使用和运维成本，目前已在电动叉车、小型挖掘机、电动农机等设备上大规模应用。

Sodium-ion Battery is very suitable for light electric construction machinery, electric forklifts, small agricultural machinery and other engineering equipment scenarios, and is the core power supply choice for the electrification of construction machinery. The core requirements for batteries in construction machinery are high rate discharge, strong power, durable and reliable performance, vibration resistance, high and low temperature adaptation, and low cost. Sodium batteries have excellent high rate charge and discharge performance, can realize instantaneous high power output, and meet the power demand of construction machinery; they have strong structural stability, are resistant to vibration and impact, and can adapt to the complex operation conditions of construction machinery; they have excellent high and low temperature resistance, and can work stably in outdoor severe cold and hot environments; at the same time, the cost is much lower than that of lithium batteries, and the cycle life is long, which can greatly reduce the use and operation and maintenance costs of construction machinery. At present, they have been widely used in electric forklifts, small excavators, electric agricultural machinery and other equipment.
