Abstract

This invention relates to battery test system, which comprises charge unit and battery, wherein, the system comprises control unit, sensor unit and the control unit is to receive battery property data from sensor unit and to send charge or stop orders to charge unit; the said control unit and sensor unit and charge unit are connected; the sensor unit is to collect battery property data.

Description

technical field [0001] The present invention relates to a test system, in particular to a battery test system and a test method. Background technique [0002] The charging performance of the battery has an important impact on the service life of the battery. [0003] After the battery is fully charged after a certain charging process, continue to charge. If the charging current is too large or the charging time is too long, the oxygen generated inside the battery will not be consumed in time, which may cause internal pressure rise, battery deformation, liquid leakage, etc. unpleasant sight. At the same time, its electrical performance will be significantly reduced. [0004] For lithium-ion batteries, the charging requirements are even more stringent. When a lithium-ion battery is being charged, lithium ions will dissolve out of the layered structure and enter the negative electrode. If it is overcharged, the lithium ions in the positive electrode will dissolve too much, ...
