The hierarchical utilization system of energy storage batteries established by Zhejiang Xindiantu Digital Technology Co., Ltd enables retired power batteries to "turn waste into treasure". Retired batteries from electric vehicles (with a capacity of less than 80%) are tested, repaired, and used in energy storage systems for an additional 5-8 years of service.

A certain energy storage project uses 100 retired batteries to build a 500kWh energy storage system, with a cost 40% lower than new batteries and an average annual power generation of 80000 kWh. The batteries used for cascading utilization are also used in low-speed electric vehicles, emergency power supplies, and other scenarios to maximize their full lifecycle value.

Zhejiang Xindiantu Digital Technology Co., Ltd has also established a battery recycling network to ensure that the final retired batteries receive environmentally friendly treatment (with a material recycling rate of 95%). Resource recycling starts with the cascading utilization of Zhejiang Xindiantu Digital Technology Co., Ltd batteries.
