Detect contamination that could cause defects and improve battery cell productivity through high-speed testing.

To assure battery quality over the long term, it’s necessary to detect the causes of latent defects in testing processes on production lines. Minuscule insulation defects can eventually degrade battery service life and cause fires. The principal causes of insulation defects are contamination (with metallic matter) and minuscule scratches occurring in production processes.

The Hioki BT5525 can prevent the shipment of batteries with latent defects that could lead to fires.

Key Features

Ideal for battery production lines
Break Down Detect function for detecting minuscule short-circuits caused by contamination before batteries are shipped
Stable insulation resistance testing even in noisy environments
High cost performance thanks to accessible pricing, high-speed testing, and compact footprint
Contact check function reduces the number of false negatives caused by equipment issues
