The type code of the lithium-ion battery module consists of four characters:
The first character (M): Identification code of battery module;
The second character (M): Battery type, lithium-ion manganese oxide battery;
The third character (B): Battery type, see 4.1.1;
The fourth character (C): Functional configuration of battery management
system (BMS), see 4.1.2.
4.2.2 Electric energy
The rated electric energy is represented by three effective Arabic numerals; the
unit is kilowatt·hour (kW·h).
When the electric energy is less than 10 kW·h, keep 2 decimal places, such as
9.85 kW·h;
When the electric energy is greater than or equal to 10 kW·h BUT less than 100
kW·h, keep one decimal place, such as 13.7 kW·h;
When the electric energy 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 nominal voltage (U) of the formed lithium-ion battery module, in the unit of
V.
4.2.4 Rated discharge current/peak discharge current multiple
The rated discharge current is the rated discharge current (I) of the lithium-ion
battery module, in the unit of A.
The maximum discharge current is the product of the rated discharge current
value multiplied by the peak discharge current multiple (K), in the unit of A.
4.2.5 Structure code of module box
The structure code of the lithium-ion battery module box shall comply with the
requirements in JB/T 11141-2011.
1) The communication interface shall comply with the provisions of
Chapter 4 in JB/T 11138-2011.
2) The communication protocol shall comply with the provisions of Chapter
5 in JB/T 11138-2011.
5.4.5 Compliance and reliability
5.4.5.1 Compliance
The compliance requirements for the interface and communication protocol of
the lithium-ion manganese oxide battery module are divided into:
a) Compliance requirements for circuit interface and interface protocol,
including:
1) Compliance of WDT circuit interface and interface protocol;
2) Compliance of the interface of the charge and discharge control circuit
AND the interface protocol;
3) Compliance of the I/O charge and discharge interface circuit and
interface protocol.
The circuit interface and interface protocol shall comply with the provisions
of 4.2.3, 4.3.2, 4.3.3, 4.4 in JB/T 11138-2011.
b) Compliance of communication interface and communication protocol:
When the CAN communication interface of the lithium-ion manganese
oxide battery module is connected to the internal interface of the battery
assembly, it is automatically set as the internal interface AND execute the
communication protocol of internal interface. When connected to a charge
equipment, it is automatically set as a charge and discharge interface,
AND execute the communication protocol of the charge and discharge
interface. For this reason, the communication interface and
communication protocol of the lithium-ion manganese oxide battery
module shall meet the following compliance requirements:
1) Compliance of internal communication interface and communication
protocol;
2) Compliance of charge and discharge communication interface and
communication protocol.
The communication interface and communication protocol of the lithium-ion
battery assembly shall comply with the provisions of Chapter 5 and Chapter 6
in JB/T 11138-2011.
