3D‐printable parts

Here's a collection of 3D-printable parts that you can utilize in your build.

Board fixtures / enclosures~

BMW iX, i4‐i7 (Gen5)~

  • covers for the large rear connector, smaller front connector and internal blanking covers for BMU: Thingiverse.

BYD Vehicles~

Ford Mach‐E~

Kia/Hyundai 39/64kWh~

Nissan LEAF~

Heater port cover~

The 2013-2023 batteries have an external high voltage heater port. The socket can be covered with 3D printed backoff. It can also be plugged with silicone, but beware that certain types of silicone are conductive while uncured. Allow the silicone to cure for 24 hours before engaging contactors in such a case.

LV connector cover and fixation ring~

This is a dust and water spill protection cover for the data connector of Nissan Leaf 2011-2023 batteries. It slides on top of the connector, and uses two cable glands (a PG9 and a PG13.5) to access separately the CAN and a contactor control / BMS power cables:

There's also a fixation ring for the data connector socket on 2023+. It slides in the knot at the base of the socket. Use it to prevent the socket to fall into the battery - this can occur when the workers who originally dismounted the battery pack from the car were not careful enough and lost the original spring. This ring is a quick fix you can apply without having to open up the battery penthouse.

LV connector~

If you can't source the original Yazaki sockets, you can use these models to keep dupont pins in place: ZE0 ZE0 with tabs, AZE0/ZE1.

Service Disconnect Switch~

Here is a 3D printed SDS for 2013-2023 batteries (AZE0, ZE1) 3d_AZE0_ZE1_SDS

The link contains the drawing of the copper contact part, you can cut yourself and/or ask a workshop to cut and silver-plate it.

HV Connector~

If you are mounting the battery indoors, you can also 3D-print a high voltage plug. This is generally not recommended, due to no IP rating, and no voltage rating. So try to source a real HV connector if possible! That said, this is the link to Pelle_C's excellent 3d-printable connector: gitlab/pelle8

CAUTION

Working with high voltage is dangerous. Always follow local laws and regulations regarding high voltage work. If you are unsure about the rules in your country, consult a licensed electrician for more information.
