Rav4-EV Validation Prototype Battery Monitor


The following pictures show a custom traction pack monitoring system
developed by this vehicle's previous owner.

It displays traction pack overall voltage, module high - average - and
voltages, individual module voltages, ambient, front,
middle and rear traction pack temperatures. The monitor updates
once per second.

A very useful tool for actively monitoring the traction pack in
real time, and even
more important for working with older traction
packs. This vehicle's original modules are
20 years of age (c2017).

The monitor is linked via a 3a always-ON fuse to the auxiliary
battery circuit
and transmits data in either the key-ON
or charger-ON modes. We have also added a micro on / off toggle
switch to the dash for easy operation.

A very well conceived and useful modification.
