Testing a battery before purchasing

It is possible to connect the Battery-Emulator up to the battery, with a 12V lead acid battery, and read out the battery cellvoltages and statistics before purchasing a battery. To do this, you will need Pin 1 3 4 5 6 7 12 (see the wiring diagram further down)

Compiling the software for Gen1 Zoe

When using the 22/41kWh Gen1 battery, be sure to enable the line #define RENAULT_ZOE_GEN1_BATTERY in the USER_SETTINGS.h file. You can also enable Automated Contactor Control via GPIO pins to automatically turn on the conactors when the emulator turns on, skipping the need for manually supplying power to the pins.

Safety fuse/switch

Note the battery fuse. Do not confuse it with the version from the 52kWh battery, using the incorrect one could result in blown fuses or worse. Use OEM fuse, part no: TBC (This part no. is for the sticker not the fuse: 993B1 5333R)

Renault ZOE Gen 1 fuse has to have continiuity between two external sides (positive line): image

There are also two other fuses inside the pack. There is a fuse under the cover for the contactors and a fuse at the join of the two halves of the pack at the opposite end from the connectors. If the fuse in the middle of the pack blows, this shows as a cell imbalance with cell 48 being somewhere around 0v. Replacing the fuse restores operation.

Troubleshooting

  • If the cell number 48 is low, your internal battery fuse most likely has blown. Then you need to open up the battery and replace the fuse.
