4 Classification and Model
4.1 Classification
4.1.1 According to the battery type, it can be divided as follows:
--- Energy type lithium iron phosphate battery module (Code E);
--- 48/16: A battery module composed of 16 (16) batteries in series with a nominal voltage
of 48 V (48);
--- 50/9: The rated discharge current is 50 A (50), and the maximum discharge current is
450 A (50 A × 9);
--- 4007: The battery module adopts a standard battery module case with a type code of
4007.
4.2.1 Type code
The type code of the lithium-ion battery module consists of four characters:
The first character (M): Battery module identification code;
The second character (F): Battery category, lithium iron phosphate battery;
The third character (B): Battery type, see 4.1.1;
The fourth character (C): Function configuration of battery management system (BMS),
see 4.1.2.
4.2.2 Rated power
The rated power is represented by three significant Arabic numerals, and the unit is
kW • h.
When the rated power is less than 10 kW • h, retain 2 digits after decimal point, such
as 9.85 kW • h;
When the rated power is greater than or equal to 10 kW • h, but less than 100 kW • h,
retain 1 digit after decimal point, such as 13.7 kW • h;
When the rated power is greater than or equal to 100 kW • h, it is represented by a 3-
digit integer, such as 143 kW • h.
4.2.3 Nominal voltage/the number of modules
The nominal voltage (U) of the battery modules that compose of the lithium-ion battery
assembly, in V.
The number of battery modules (N) that compose of the lithium-ion battery assembly.
The nominal voltage of the battery assembly is equal to the algebraic sum of the
nominal voltages of the modules.
