Advanced Safety Tester (ADST Series)
Lithium-ion secondary batteries are adopted wider applications in everything from consumer use to storage and automobiles, and there is greater interest not only in advancing performance testing but also in safety testing. ESPEC designed the Advanced Safety Tester to perform multiple safety tests under precise temperature environments.
Tests such as nail penetration, crushing, short circuit and overcharge/discharge testing is possible in a temperature (&humidity) controlled space. Constructed with an integrated system using a measurement control unit this system provides centralised management of testing operations and minimizes complex operations for performing tests.
One unit with four functions:
The function elements of the safety tester are in separate modules, enabling flexible system construction and expansion.
The combination of each unit enables support of batteries from small cells to large packs.
Constructed with an integrated system using a measurement control unit. This system provides central management of testing operations and minimizes complex operations for performing tests.
One-stop service provides enhanced product and service quality as well as speed.
