| ① | BMU (Battery Management Unit) |
2G type | BMU monitors the cell voltage and temperature of each battery module, and protects the battery if an abnormality is detected. Additionally, this measures the charge/discharge current, and calculates the SOC value. Furthermore, this notifies the upper controller of the battery information, measurement/calculation information, etc. via Ethernet or CAN communication. | |
| ② | Contactor |
S type (Standard) |
The contactors are installed respectively to the positive terminal and negative terminal of the main circuit to shut down the main circuit in response to instructions from BMU if an abnormality occurs in the battery. * The drive signal cable comes with the H type. |
|
| H type (High current) |
|
|||
| ③ | Current leak sensor (ELS) | The current leak sensor detects leakage in response to instructions on the fault diagnostic signal from the upper controller after the main circuit is shut down. | |
|
| ④ | Current sensor (HCT) | C2 type | The current sensor measures the charging/discharging current. The measured data is sent to BMU via CAN communication. |  |
| ⑤ | Battery module(MDL) |
Type3 | The battery module consists of 24 cells (2 in parallel and 12 in series), and incorporates the cell monitoring unit (CMU) that monitors the voltage and temperature of these cells. |  |
| ⑥ | Termination plug (TP) | The termination plug is the termination resistor for CAN communication. | |
|
| ⑦ | Service disconnect(SDC) |
SDC-750 | The service disconnect is used to disconnect the main circuit when installing / removing the battery module or during the maintenance work. The built-in fast acting fuse to protect the battery in the case of external short circuit. * SDC-1500 does not have a built-in protection fuse. Use a commercially-available fuse additionally.
