Renault Kangoo 36

The phase 2 Renault Kangoo 36kWh pack consists of 12 modules, roughly 16kg 14x21x31 cm each in a 2P8S configuration. The usable capacity is apparently 33kWh. It uses a centralised BMS, like the Nissan Leaf, as opposed to a distributed BMS with each module having it's own satellite board. So care must be taken to ensure the cell tap plugs are connected in to the modules in the correct order or the BMS may be damaged. Also note the cell taps will have potentially high voltage across them.

Contactor Box

The pack doesn't have a negative contactor, the only way to isolate it is to pull the service disconnect. In the contactor box there's a current sensor, pre-charge resistor, pre-charge relay, main contactor and a 275a 1000V fuse.

The main contactor is 150a rated.

There are 2 external Low voltage Connectors for the battery pack.

I've started putting together a DBC file, but this only covers the standard CAN frames.

DBC file:

For the BMS to send out can frame a message on 0x423 needs to be sent.

When driving the contents of the 0x423 message is

0x07 0x1D 0x00 0x02 0x5D 0x80 0x5D 0xD8

When charging the contents of 0x423 is

0x0B 0x1D 0x00 0x02 0xB2 0x20 0xB2 0xD9

And When rapid charging the contents of 0x423 is

0x07 0x1E 0x00 0x01 0x5D 0x20 0xB2 0xC7

I've not yet tested what affect these different messages have, if any.


To get the individual cell voltages and some other information, ISO TP requests are required. I've written some code that'll decode these. Will be extending to run on an ESP32 to make the ISO-TP requests and decode.
