Electric Vehicle
Management System
v2.0
The ultimate multifunctional,
integrated control system for your EV
Introduction
Thank you for purchasing ZEVA’s Electric Vehicle Management System. The EVMS was
developed to address the need for safer, more reliable and better integrated EV conversions.
It combines many common functions and a range of fault detection, providing warnings of
operating errors and automatically responding to serious faults.
Instrumentation including voltage, current, power, battery charge, temperature, and
•
insulation integrity.
Analog gauge outputs to re-use OEM fuel gauge, temp gauge and tachometer.
•
Battery management including cell voltage and temperature monitoring with auto-
•
matic response to under/over-charged batteries, and automatic pack balancing.
Contactor control for management of auxiliary contactors, allowing battery pack
•
break-up and isolation for safety when vehicle is not in use.
Optional 2-stage precharger with fault detection for soft-starting motor controllers
•
Detection of over 15 different operating errors/warnings.
•
A complete EVMS consists of a Core, usually installed in the vehicle’s engine bay,
communicating over industry-standard CAN bus with a Monitor module in the vehicle
cabin, and battery management modules located within your battery boxes.
This manual describes the installation and operation of both the EVMS Core and EVMS
Monitor devices. Please refer to documentation supplied with your BMS modules for
information relating to those devices.
Safety Warning
Electric vehicles are high powered machines which involve potentially lethal voltages and
currents. Proper precautions and electrical safety procedures should always be observed,
voltages above 110VDC should be considered dangerous, and vehicles should never be
worked on while power contactor(s) are engaged. Please read this manual carefully to
ensure correct installation and operation. If you are unsure of anything, please contact us
before proceeding.
We have endeavoured to make a safe and reliable product which performs as described,
however since ZEVA has no control over the integration of its products into a vehicle, we can
assume no responsibility for the final safety or functionality of the completed vehicle.
It is up to the end user to determine the suitability of the products for the purpose employed,
and the end user assumes all risks associated. Products should only be installed by suitably
qualified and experienced persons, and should always be used in a safe and lawful
manner.
