Enables various standards compliance testing combining temperature conditions and charge/discharge conditions.

Enables synchronous operation of temperature tank and charge/discharge power supply.

Power supply run in parallel creates high power.(Restrictions on voltage and current exist.) Can be used for state of charge adjustments in safety testing for compliance with regulations required for lithium-ion batteries such as the UN Recommendations on the Transport of Dangerous Goods, and UNECE Regulation R100.Enables evaluation testing such as constant-current/voltage discharge tests, discharge temperature characteristic tests and discharge rate characteristic tests.Reduces power loss caused by cables and improves electrical response, enabling high-precision, high-quality testing. The integrated structure of the charge/discharge controller and temperature chamber creates an in-chamber, cable-free design.Test Navi: Impact assessment in safety testing of lithium-ion secondary battery ( 165KB) Test Navi: Lithium-ion secondary battery accelerated testing ( 270KB) Test Navi: Secondary battery assessment method ( 66KB) We also have a comprehensive range of testing/certification services for compliance with UNECE Regulation R100.Įnergy Device Environmental Test Center Related pages In addition to charge/discharge testing, ESPEC provides lithium-ion battery evaluations, and safety testing, test consulting and certification services for vehicle battery packs/modules. There are discharge load characteristic tests (in which the current rate is varied when the sample is discharging), and charge load characteristic tests (in which the current rate is varied when the sample is charging). There are discharge temperature characteristic tests and charge temperature characteristic tests.Ĭonstant-current load characteristic testing is done to determine how much capacity can be input/output with varying current rates. Temperature characteristic testing is done to determine how much capacity can be input/output under several different temperature conditions. Some profiles have a slightly larger charge quantity than discharge quantity, and others have a slightly larger discharge quantity than charge quantity. A combination of charge/discharge profiles is used. For vehicle batteries, IEC 62660-1 calls for cycle life testing with the charge/discharge rates rapidly varied. Temperature cycle testing is also often performed, in which the test temperature is raised and lowered by placing the sample in a temperature chamber. The standard method is to charge and discharge repeatedly at the recommended charge and discharge rates. The test objective is to determine the number of times a battery can be used by evaluating it until it deteriorates after repeated cycles of charging and discharging. Charge/discharge cycle testing is one evaluation test method used to meet this demand. The growth of devices running on lithium-ion batteries has created demand for high levels of precision and quality to support various applications.
