Charge And Discharge Performance 

Item Test Item Specification Test condition
4.6.1 Discharge performance

Capacity @ 0.5ItA discharge / Capacity @ 0.2ItA discharge ≥95%;

Capacity @ 1.0ItA discharge / Capacity @ 0.2ItA discharge ≥90%;

Capacity @10.0ItA discharge / Capacity @ 0.2ItA discharge ≥80%

Under the conditions:23±2℃,65±5%RH, stand charge first, then discharge with 0.2C to 2.75V/cell;and then standard charge, then discharge with 0.5C to 2.75V/cell;standard charge again, then discharge with 1.0C to 2.75V/cell;finally standard charge, and then discharge with 10.0C to 2.75V/cell,record the capacity @different discharge current.
4.6.2 Life cycle Remained capacity/Initial capacity≥80% Under the conditions:23±2℃,65±5%RH, standard charge first,then standard discharge, record the initial capacity. The battery repeat for 300 cycles as above, and calculate the remained capacity percentage.
4.6.3

High/Low temp.

performance

In stand discharge,

Capacity @ -10℃ discharge / Capacity @ 23℃ discharge ≥80%;

Capacity @ 0℃ discharge / Capacity @ 23℃ discharge ≥90%;

Capacity @ 60℃ discharge / Capacity @ 23℃ discharge ≥95%;

In fast discharge,

Capacity @ -10℃ discharge / Capacity @ 23℃ discharge ≥75%;

Capacity @ 0℃ discharge / Capacity @ 23℃ discharge ≥85%;

Capacity @ 60℃ discharge / Capacity @ 23℃ discharge ≥90%;

Store the battery for 3h under 23℃, standard charge under 23℃,then standard discharge under 23℃; repeat the first step; and then store for 3h under 23℃, standard charge under 23℃, and standard discharge under 0℃; and then store for 3h under 23℃, standard charge under 23℃, and standard discharge under 60℃; record the capacity @ different discharge temp.;

Use another battery to be test as above,but fast discharge the battery in different temp. and record the capacity @ different discharge temp.

4.6.4 Storage Remained capacity/ Initial capacity≥85% Under the conditions:23±2℃,65±5%RH, standard charge first,then standard discharge, record the initial capacity, and then store the battery for 28 days under 25℃,after storage, standard discharge the battery and record as remained capacity, to calculate the remained capacity percentage.
