4.5 PARALLEL USE OF BATTERIES
•
MD48-50-2U and MD48-100-3U support multi machine parallel connection to
increase capacity. They support up to 15 parallel units respectively.
•
For parallel connection between batteries and communication cascade
between batteries, the original cable of BST must be used.
•
Conditions for parallel connection of multiple batteries: the SOC is the same,
and the voltage difference between batteries is less than 1V.
•
It is recommended that the output current of the single battery be lower than
0.5C.
•
When the total output current is less than 100A, a single cable connection shall
be adopted, and the power cable must be output from the top and bottom
batteries respectively. As shown in Figure 4.5.1 below.
•
When the total output current is greater than 100A and less than 200A, the
two-wire cable shall be used for connection, and the power cable must be
output from the top and bottom batteries respectively. As shown in Figure 4.5.2
below.
