Start arranging the battery packs in ascending numerical order. Connect each cells terminal to the opposite terminal of the next cell-negative to positive. The negative terminal of cell №1 is the battery pack`s negative terminal. Begin with SLAVE №1 using cable bundle №1. Connect wire “-1” to the negative terminal of cell №1, and wire “+1” to the positive one. Next cell is №2. Connect wire “+2” to the cell`s positive terminal and so on up to wire “+12” (connected to the positive terminal of cell №12) according to the picture shown below. Continue with SLAVE №2 by using cable bundle №2. Connect cell`s №13 negative terminal to wire “-1” from cable bundle №2 and so on. If the available cells for any SLAVE are less than twelve, then connect all free wires, including wire “+12”, to the positive terminal of the last cell.
The connection between SLAVE UNITS is built by “Slave” wires (written on their ends), and the connection between MASTER and SLAVE UNITS is built by wire “Master-Slave”, respectively connected.
If your CHARGER is TC-Charger, then connect the blue coupling “PWM Charge” to it.
Drive across charger`s and load`s wires through HALL SENSOR following the current`s direction!
Always use contactors and fuses for power circuit breaking!
The relay outputs have normally open and normally closed contacts. You can use it for different applications, for example: to interrupt the regenerative mode when the cells get charged or to restrict the car`s maximum speed when the cells energy store is under the undervoltage limit.
Always check the wires insulation and the connections between them.
