Description
| Component | Function | |
|---|---|---|
| Battery current sensor | Current sensor | Detects the charging/discharging current of the battery. |
| Temperature sensor | Detects the temperature around the battery. | |
| Battery | Battery supplies power supply voltage to each unit and parts. | |
| IPDM E/R | The IPDM E/R transmits the generator voltage request signal to the ECM via CAN communication according to battery voltage and the battery temperature sensor signal. | |
| ECM | The ECM controls power generation voltage to the generator according to the request from the IPDM E/R received via CAN communication. | |
Signal transmission function list
| Signal name | Input | Output | Description |
|---|---|---|---|
| Battery current sensor signal | Battery current sensor | IPDM E/R | Transmits the battery current sensor signal to the IPDM E/R. |
| Battery temperature sensor signal | Battery current sensor | IPDM E/R | Transmits the battery temperature sensor signal to the IPDM E/R. |
| Generator voltage request signal | IPDM E/R | ECM (CAN) | Transmits the generator voltage request signal via CAN communication. |
SYSTEM DESCRIPTION
The IPDM E/R has an energy management system that recognizes the battery status from the battery current signal from the battery current sensor, the battery temperature sensor signal, and the battery voltage from the battery and maintains normal battery status. Refer to the following for details:
