Vehicles wading through water, high humidity along the coast, extreme cold and heat...The usage scenarios of automotive lithium batteries are becoming increasingly demanding, and sealing defects invisible to the naked eye may lead to the risk of thermal runaway.Traditional testing solutions often face a dilemma: it requires high-voltage detection of direct cooling plates (2MPa) and liquid-cooling plates (350kPa), and low-voltage leak detection of battery packs (20kPa), which requires equipment switching.This not only slows down the delivery pace, but also doubles the company's initial capital costs due to high procurement costs.

Hirays one-stop battery sealing testing solution

Industry pain points:

a.Multiple stress problems:The direct cooling plate needs to withstand 2MPa and the liquid cooling plate can withstand 350kPa high pressure, while the battery pack body only needs 20kPa low pressure leak detection. The traditional solution generally requires two sets of equipment, resulting in a bloated production line and doubling of equipment and management costs;

b. The charging stage of the 40L battery pack starts in 3 minutes.Occupying 70% of the inspection cycle, seriously dragging down production capacity；

c. Manually recorded data errors frequently occur, making it difficult to trace defective products.

As an industry expert with nearly 20 years of experience in the field of sealing and leakage detection, Hirays has delivered one-stop customized sealing detection solutions and equipment to a number of leading battery companies by virtue of its independently developed core software and hardware technologies, as well as its high-precision and high-stability equipment advantages.
