20 years experience in electric vehicle applications, development of electrical complete Zero or low emission transportation concepts makes EVM the ideal partner for all EV applications.
Batteries
Lead Acid Batteries
Main used battery in electric vehicle application. Major advantages are low cost, good cycle life, easy to recycle. Disadvantages are low energy density and heavy weight. Small electric vehicles with low voltage drive system are best served with a flooded product, preferably a thin tubular plate product. Higher voltage systems and all hybrid vehicles should be fitted with Valve regulated batteries. Gel technology is best in cycle life, where Agm batteries perform better at high current discharge.
NiZh + NiMeH
Ni-Zn is a relatively new Ni-based battery technology; absolutely maintenance free and a good energy density are the major advantages. Ni.MeH, one of the successful advanced battery systems is available in higher capacities. Many hybrid vehicles are powered by this battery technology.

Sensor Technologies
AC Sensor
ABERTAX Technologies offers a number of sensors to suit any application environment. Sensors are available to measure a number of parameters, namely:

- Electrolyte level
- Thermal level
- Liquid in tray


Such sensors are in turn available in a number of configurations to meet a number of installation requirements namely:

- Multi-layer batteries
- External LEDs for dashboard mounted applications
- External probe for ease of installation
- Beeper to provide audio output as well as visual indication
Management Systems
BMU / BMS
The Battery Monitoring System (BMS) gives essential battery information which includes: the number of charge/discharge cycles, temperature and electrolyte low level timings amongst others. All this information can then be downloaded to a PC for further evaluation.

The Battery Management Unit (BMU) can control batteries having voltages from 24V to 96V. The BMU is capable of storing a set of parameters for a number of cycles. These parameters also include the ones mentioned above for the Battery Monitoring System. The BMU has an external temperature sensor as well as an optional external level sensor for flooded battery applications.

The data from the BMU can be transferred to a PC via a number of ways namely RS232, USB, GPRS, Bluetooth and Wifi.
Magnetic Valves
Water Inlet Valve
ABERTAX Technologies also provides solutions for water inlet valves. Such valves feature a magnet which in turn operates a diaphragm type valve. As the water level rises, a float will rise with it until the magnet moves a plunger to close the valve.
VRLA Accessories
GRS
A Gas Release System is available for Gel and AGM batteries. This system offers the ideal control valve for gas release in such battery types. The design incorporates a feature which acts as a fire barrier, thus greatly reducing the possibility of fire entering the cell and thus enhancing the overall safety of the system.
Intelligent Battery
This is an innovative concept which offers a modular battery box to facilitate installation and reduce the number of connectors required. This comes from the length to width ratio allowing any direction of assembling. An optional feature is an electronic management system which controls battery operations. This module also stores a number of parameters which can also be then transferred to a PC.
