With the acceleration of global energy structure transformation and the increasing demand for green travel among consumers, portable energy storage has become increasingly popular in recent yearsindustryRapid development has become an important support for outdoor activities and emergency scenarios.According to data from the China Chemical and Physical Power Industry Association, portable energy storage devices2026Annual Global Market SizeUp to882RMB100mn，Total output value of the Chinese marketsuper700RMB100mn

Customer A is one of the top 3 portable energy storage companies in the worldFocusing on the field of portable energy storage and household green energy systems, we aim to build an integrated system of research and development, production, and salesM2C Business ModelOur products cover more than 30 countries and regions worldwide, with a global coverage of ≥ 10%.

Testing requirements:

Core components of portable energy storage devicesBidirectional boost DC to DC, bidirectional inverter, DC output fast chargingConduct comprehensive functional verification testing based on module performance indicators. Based on previous technical exchanges, the customer needs to conduct functional testing on their latest portable energy storage device product. The traditional testing plan is as follows:

The internal battery pack of outdoor energy storage power products is generally controlled within a voltage of 60V, and the battery cells are controlled within 16 stringsTernary lithium battery and lithium iron phosphate batteryMainly, the current is normally controlled within 350A, and the direction of charging and discharging current can be freely switched.

Testing both directionsDC/DCWhen it comes to modules and bidirectional inverter modules, it is necessary to complete functional and performance testing for this module. During research and development testing, a high-voltage bidirectional high-voltage direct current power supply is also required, which can simulate high-voltage loads and achieve free switching by simulating high-voltage direct current power supply. The voltage control should be within700VWithin, the power is controlled within12kW左右。

Traditional testing solutions rely on multiple devicesandConnected, there are problems such as complex wiring, high energy consumption, and difficult data synchronization, especially when verifying batteriesCharge and discharge performanceWhen it comes to key indicators such as inverter efficiency,Test efficiencylower，influenceproductListing and Customer Operations.

Based on the pain points of customer testing in the early stage, after customer communication, product trial, and reliability testing,NGIprovideN35500Series and N35100 seriesProgrammable bidirectional DC power supply, matching R&D, production line and other testing requirements:

collocationNS81000 Battery Simulation SoftwareIt can accurately simulate the battery characteristic curve, meet the simulation needs of users for different types of batteries, and improve testing efficiency.

Compared to the traditional positive and negative current switching scheme implemented by power sources and loads,Bidirectional power supply canHigh speed conversion between source and load modesAchieve seamless switchingEffectively avoiding voltage or current overshoot, without the need to replace instruments, making testing simpler.

Small size, high power density, 1U chassis integrated with 7500W,Save over 50% compared to traditional testing power supplyEffectively saving customer testing space.

After the customer adopted NGI bidirectional DC power supply, the single cycle testing time was greatly reduced, while effectively reducing procurement costs. This technology is becoming a key engine driving the iteration of portable energy storage device products and seizing market opportunities.

In addition, NGI can also provide high-performance battery cell simulators, simulated fast charging electronic loads, and other products that can be used for portable energy storage productsBattery Protection BoardFast charging port and other tests.
