纽约的两家公用事业公司正在使用凯斯580 EV挖掘装载机，这是去年在Conexpo展会上推出的电动产品。
纽约州天然气和电力公司和Rochester天然气和电力公司各有一台Case 580 EV电动挖掘装载机。挖掘装载机的电气化是与纽约公司Green Machine Equipment、Moog联合进行的。纽约的Monroe Tractor公司将在现场为这些机器提供支持。
580 EV由Green Machine公司专有的480伏、90千瓦时锂离子WhisperDrive电池组供电，该电池组可以通过任何220伏电源进行充电。尽管设备用于各种作业，但每次充电都可以满足8小时工作日的需要。凯斯表示，该电池分别为动力传动系统和液压马达提供动力，从而产生与柴油动力机器相同的液压挖掘力，并在同时进行装载机和动力传动系统操作时提高了性能。
凯斯表示，考虑到减少了柴油、机油、柴油机尾气处理液，定期的预防性维护以及长期的发动机维护/保养，580 EV挖掘装载机每年可以为车队节省多达90％的车辆服务和维护成本，并且可以节省相关的人工费和时间。

Case EV Backhoes Delivered in New York
Two New York utilities are using Case 580 EV backhoe loaders, the electric machine introduced at Conexpo last year.
New York State Gas & Electric and Rochester Gas & Electric each have a Case 580 EV electric backhoe loader. ElectrifiCATion of the backhoe loader was performed in conjunction with New York companies Green Machine Equipment, Inc. and Moog Inc. Monroe Tractor in New York will support the machines in the field.
NYSEG and RG&E president/CEO Carl Taylor said that the deployment of electric construction equipment into the communities they serve is driven by sustainability and the desire to be responsible neighbors.
“At NYSEG and RG&E, the driving force behind all of our decisions is to put our customers first and care for the communities we serve,” he said in a prepared statement. “As an energy provider, we have a responsibility to be good stewards of the environment and build a more sustainable future for our communities. The addition of this first-of-its-kind backhoe into our fleet will help us meet sustainability goals and benefit the communities we serve by providing a cleaner work environment in the form of emissions and noise reduction. It’s equipment like this that will drive our fleets, businesses and communities into the future.”
The 580 EV is powered by Green Machine’s proprietary 480-volt, 90-kilowatt-hour lithium-ion WhisperDrive battery pack that can be charged by any 220-volt connection. Although appliCATions vary, each charge can support common eight-hour workdays. The battery separately powers the drivetrain and hydraulic motors, resulting in hydraulic breakout forces equal to diesel-powered machines and improved performance during simultaneous loader and drivetrain operation, according to Case.
Case estimates that the 580 EV could save fleets as much as 90 percent in annual vehicle service and maintenance costs when taking into account the reduction/elimination of diesel, engine oil, diesel exhaust fluid, regular preventive maintenance, and long-term engine upkeep/maintenance (and the associated labor rates and time savings).
