Standard Charging Model:
At room temperature, charged to 4.35V at a constant current of 169A, and then, changed continuously with constant voltage of 4.35V until the current was not more than 8.4±0.5A.
Absolute Charging Temperature:
No matter what the charging model is, once the temperature of the cell is above the absolute charging temperature, charging should be stopped.
Absolute Charging Voltage:
No matter what the charging model is, including pulse charging, once the voltage of the cell is above the absolute charging voltage, charging should be stopped.
Standard Discharging Model:
At room temperature, discharged to 2.8V at a constant current of 169A.
Maximum pulse charging current allowed:
During the process of product being used, pulse current created in regenerative braking can recharge the battery. Maximum charging current allowed and the pulse duration in different temperature conditions must strictly observe the conditions listed in the following table. Violating the described conditions may cause permanent damage to the battery and thus is exempt from the responsibility of CALB for product quality.
After each brake charging, the battery needs to rest for certain time, which should be equal to or longer than the duration of the pulse charging. During the rest, the battery can be in the discharged state, or in a non-working state. But in the rest period, the battery is not allowed to pulse recharge again.
Precautions for Transportation:
The batteries should be packed in boxes for transportation which should be conducted not less than 30% SOC. They are also should be prevented from vibration, shock, extrusion, sun-scorched and rain-drenched. It could be delivered by car, train, boat, etc. If it will be delivered by air, please refer to MH/T 1020-2013 Standards for transport of lithium batteries by air.
Precautions for Storage:
The batteries should be stored (more than 1 month) in a clear, dry and ventilated room under ambient temperature of -20℃~25℃, and it should be kept away from caustic material, combustion source and heat source. Do not turn over battery during storage; mechanical shock and stress should be avoided.
If the batteries kept unused for a long time, it should be charged and discharged at the standard model every six months. Store the battery in the state of 10%~30% SOC.
