1.Definition Of Terms For CATL 240ah cell
term
definition
product
The “Product” in this specification refers to the 240Ah 3.2V rechargeable lithium iron phosphate energy storage battery produced by CATL.
client
Refers to the buyer in the CATL EV Product Sales Contract.
CATL
Refers to the seller in the CATL EV Product Sales Contract.
PN
In order to distinguish the battery application in different use areas or under different application conditions, C A TL is 24 0 A h 3.2 V Material number defined by rechargeable lithium battery.
Ambient temperature
The ambient temperature of the battery. The temperature tolerance is ±2℃.
Battery management system( BMS)
A customer monitoring and recording system that tracks and records operational parameters of a product throughout its service life. The tracked parameters include, but are not limited to, voltage, current, temperature, etc., to control the products operation and ensure that the operating environment and conditions comply with the specifications in this specification.
Temperature of cell
The temperature of the cell is measured by a temperature sensor attached to the battery, and the selection of the temperature sensor and measurement circuit is agreed between CATL and the customer.
Fresh battery status
Refers to the status within a 7-day period from the date of battery manufacturing
C-Rate Charging Rate
The ratio of the charging current to the battery capacity measured multiple times by the battery management system. For example, when the battery capacity is 240Ah and the charging current is 240A, the charging rate is 1C; when the battery capacity drops to 192Ah and the charging current is 192A, the charging rate is 1C.
Cycle recurrence
A battery is charged and discharged according to the specified charging and discharging standards as one cycle. A cycle includes a short normal charging or regenerating charging and discharging process, in which there may be only normal charging without regenerating charging during the charging process; discharge may be formed by some partial discharge combinations.
date of manufacture
The manufacturing date of the battery. The date code shown on the top label of each battery is the manufacturing date.
Open circuit voltage (OCV)
The battery voltage measured without any load or circuit connected.
Recoverable capacity
After battery storage, the capacity measured according to the standard charging and discharging conditions listed in Article 2.2 and 2.3 of this specification shall be selected3. Average of the next measurement.
Product supply agreement
CATL and the customer have signed the terms of trade for the products in this specification.
Standard charging
The charging mode described in Article 2.2 of this specification.
Standard discharge
The discharge mode described in Article 2.3 of this specification.
Charging status (SOC)
The ratio of the actual charge to the full charge of the battery characterizes the charging state of the battery. The charging state of 100%SOC means that the battery is fully charged to 3.65V, and the charging state of 0%SOC means that the battery is completely discharged to 2.5V.
temperature rise
Such as the increase in cell temperature during charging or discharging as specified in this specification.
measurement unit
“V” (Volt) Volts (V), unit of voltage
“A” (Ampere) is the unit of current
“Ah” (Ampere-hour) Load unit
“Wh” (Watt-Hour) Energy unit
“Ω” (Ohm) Ohm (Ω), unit of resistance
