Many lithium battery factories choose Yishengda battery pack aging cabinets mainly because they precisely meet the five key pain points required for mass production of lithium battery packs, forming comprehensive competitive advantages in cost reduction, quality control, adaptation, safety, and service.
Aging testing is the core power-consuming process at PACK factories. Yishengda's independently developed EST energy feedback system can feed up to 94% of battery energy back into the grid during discharge, rather than traditional resistive heat dissipation; At the same time, it significantly reduces air conditioning electricity costs caused by equipment heat dissipation, achieving "dual energy savings." For medium-sized PACK factories, batch aging scenarios can save hundreds of thousands to over a million yuan in electricity costs annually, offering significant long-term operating cost advantages and serving as a core decision-making factor for most factories.
Sampling accuracy exceeds industry average: using a high-performance DSP controller + three-level IGBT/SIC solution, the voltage and current accuracy of the high-voltage cabinet reaches ±0.05%, the maximum of 0.02% for medium-voltage cabinets, with a sampling response of ≤ 1ms and a dynamic response of only 5ms, accurately capturing transient hidden defects such as micro-short circuits, cold solder joints, and differential drift in the cell. Avoid missed judgments in static tests, truly realizing the quality value of aging screening.
Single-channel independent interference-free: The modular channel is designed with independent single-point design, paired with independent air ducts for front entry and rear outlet. There is no electrical interference or thermal crosstalk between channels, and the testing conditions for each battery group are exactly consistent, ensuring consistent quality for products from the same batch and across batches, meeting the consistency requirements of large-scale mass production.
No impact damage during charging and discharging: Constant current and constant voltage ensure smooth transitions with no current or voltage spikes, avoiding damage to cell tabs and triggering BMS false protection during testing, while also reducing the risk of sparking caused by loose connectors, protecting the tested battery and electronic components.
Comprehensive safety protection: hardware is equipped with more than ten protections including overcurrent, overvoltage, overtemperature, surge prevention, and leakage protection; On the software side, it supports power outage data storage, reverse connection protection, and dynamic load protection, capable of cutting fault circuits at millisecond levels to curb thermal runaway risks, and complies with lithium battery workshop fire safety and safety supervision acceptance standards.
Data traceability and compliance: Test data is automatically recorded and exported and archived, meeting domestic and international standards such as GB/T 31467 and UN 38.3. It can be directly used for factory audits such as production licenses, automotive regulatory access, and export certification, adapting to the supplier audit requirements of downstream automakers and integrators.
