For PACK factories in production, the biggest headache is often not orders, but equipment investment.
The initial order volume was small, and they were reluctant to invest huge sums in a single purchase of high-power aging equipment. However, as the business expanded, orders for energy storage and high-current modules kept coming in, and the existing equipment could not meet the current and power requirements. Many companies have no choice but to purchase new high-power cabinets. Old equipment is idle and depreciates, factory space is heavily occupied, and multiple costs for equipment procurement, operation and maintenance, and site continue to rise, directly eating up already meager profits.
Traditional aging equipment has "one machine, one power," and the parameters are fixed once purchased. To conduct high-current PACK testing, they had to purchase complete machines anew. Early small capacity couldn't use high-power equipment, and as orders increased later, equipment capacity was insufficient, resulting in low asset utilization, becoming a hidden burden for many PACK factories.
To address the pain point of PACK factories facing "limited upfront budgets and the need for increased production capacity later," Yishengda's feedback aging cabinet adopts a modular architecture supporting multi-channel parallel capacity expansion. One device supports independent testing of small modules and parallel testing of high-current PACKs, eliminating the need to repurchase complete machines and reducing subsequent equipment investment costs from the source.
Each channel hardware of the Yishengda aging cabinet is completely independent, allowing for single-channel separate operation or software settings for multi-channel parallel output.
Scene One:
For small-batch, multi-specification orders, each channel operates independently. Two-wheelers and small energy storage packs of different voltages and capacities can simultaneously conduct aging, cycling, capacity, and DCR internal resistance tests, with channels interfering without interference, fully utilizing equipment channel resources to improve prototyping and small-batch production efficiency.
Scenario 2:
High-power energy storage and high-current module orders do not require brand-new high-power cabinets; multiple channels can be directly connected in parallel to output high current, meeting the needs of high-power PACK charging and discharge aging and rate cycle testing. Existing equipment can be directly upgraded in power, allowing old equipment to continue its value without needing to replace the entire machine, reducing the large cost of repeated equipment purchases.
Simply put: factories grow from small to large, orders shift from small modules to high-power energy storage packs, and existing cabinets can be continuously reused. Modules only need to be added as needed, without directly eliminating complete machines, greatly reducing the sunk cost of equipment for expansion.
Parallel expansion alone is not enough; Yishengda aging cabinets cover the hardware foundation while also addressing the long-term operating costs of the PACK factory:
Energy feedback technology for continuous electricity savings:
Unlike resistive aging cabinets that heat and dissipate energy, the discharge phase releases battery energy and returns it back to the grid, resulting in high efficiency and significantly reducing production power consumption. At the same time, it decreases the energy consumption of cooling and air conditioning, gradually saving considerable electricity costs.
Independent air ducts and modular hardware reduce downtime losses:
Channels are modular and independent, with independent air duct heat dissipation. Single-channel failures do not affect the continued production of other channels in the machine. Maintenance and replacement only target faulty modules, eliminating the need for full machine shutdown, reducing maintenance costs and downtime losses, and extending equipment lifespan.
High-precision stable testing to reduce defective product outflow losses:
DSP digital control offers high voltage and current sampling accuracy with minimal ripple, supporting multiple modes including constant current, constant voltage, constant power, pulse condition simulation, and DC internal resistance testing. It fully records full-process test data, helping factories screen for voltage difference and capacity abnormal PACKs, reducing after-sales rework losses.
Software adapts flexibly, no complex modifications needed:
All channel parallel switching is handled by the host computer software, with no need for hardware wiring. Switching test modes is simple and convenient, and ordinary production staff can operate it. It adapts to the production and testing needs of multiple categories of PACK products such as energy storage, two-wheelers, power tools, and portable energy storage.
Balancing the present and the future. The core value of Yishengda's modular parallel aging cabinet is to adapt to the growth path of small and medium-sized PACK factories: at the initial stage, use the right number of channels to meet existing capacity; Business expansion achieves power upgrades through channel parallelization and module addition, allowing existing equipment to continue operation, minimizing equipment sunk costs, and allocating more funds to production and order expansion.
