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
•
isolation integrity.
Battery management including cell voltage and temperature monitoring with auto-
•
matic response to under/over-charged batteries, and automatic pack balancing.
Analog gauge outputs to re-use OEM fuel gauge, temp gauge and tachometer.
•
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 many different operating errors/warnings.
•
A complete installation consists of an EVMS, usually installed in the vehicle’s engine bay,
communicating over CAN bus with a Monitor module in the vehicle cabin, and a current
sensor and battery management modules located within your battery boxes. The CAN bus
may also include up to three TC Chargers and a ZEVA motor controller.
This manual describes the installation and operation of both the EVMS and Monitor devices.
Please refer to documentation supplied with your BMS modules, motor controller and
charger for further 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 or
battery system, 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.
