Battery cascade utilization

1. Receiving and registering incoming materials

• Conduct a preliminary inspection of the battery's appearance, structural integrity, bulging, and leakage.

• Confirm the battery type (NMC / LFP / LCO, etc.)

2. Voltage and Capacity Detection

• Voltage consistency testing of individual cells/modules

• Internal resistance testing

• State of Charge (SOC) evaluation

• Performance grading: Grade A, Grade B, Grade C

3. Security Assessment

• Insulation test

• Temperature rise test

• Overcharge & over-discharge protection check

• Thermal runaway risk assessment

Ensure that only safe and reusable batteries are selected.

4. Module disassembly and structural inspection

• Disassemble the housing, wiring harness, and BMS

• Check the stability and consistency of the module structure

• Determine if reassembly is necessary

5. Matching of tiered utilization schemes

Application selection based on battery performance:

• Energy storage systems (residential/commercial/industrial)

• Backup power for communication base stations

• Low-speed vehicles

• UPS (Uninterruptible Power Supply)

• Photovoltaic energy storage systems

6. Reassembly and balancing

• Matching battery cells with the same voltage, current, and capacity

• BMS reinstallation or upgrade

• Battery module repackaging

• Balancing treatment

7. Integrity Performance Test

• Cycle life testing

• Discharge performance testing

• Fast charge/discharge capability

• High and low temperature performance

• Safety testing (short circuit / vibration / shock)

8. Production and shipping of products for reuse

• Produces energy storage modules, backup power packs, and battery systems

• Provides testing reports and quality inspection data

• Ships to the energy storage or backup power market

By screening, testing, and evaluating, used power batteries and energy storage modules can be reused in safe and suitable application scenarios, maximizing the value of resources.
