Simple CAN bus state of charge / battery voltage display

Post by clanger9 »

I made a thing: https://openinverter.org/wiki/State_of_ ... Teensy_4.0

It's a prototype CAN bus state-of-charge meter based on a Teensy 4.0. It displays a state-of-charge or voltage value according the integer number sent over CAN bus to the configured address(es)
I used a 4-digit 7-segment LED display for a proper 80's vibe.

A touch sensor allows you to toggle the display between SoC and voltage and it includes automatic night time dimming.

I plan to build it into an existing analogue ammeter on my bike project. Hopefully the code is useful for others here.

Are you getting battery voltage through can from an openinverter board? Ive been looking to see if battery voltage is available through can . Im using a dual motor board for prius gen 3 inverter.

I'm using an Isabellenhütte IVT-S for now, but I'm expecting the pack voltage and/or SOC will eventually come from the BMS (Orion)...
