PERFORMANCE

Voltmec’s unrivalled experience and expertise enable fast design, development and manufacturing of bespoke lithium batteries for every customer.

Use of state-of-the-art cells and cutting-edge control algorithms resulting from unmatched experience, these are the ingredients that produce optimum performance in terms of:

High power motorsport up to 20C
Fast chargeup to 5C: 80% in 15 minutes
Robustness under extreme
environmental conditions
active temperature management and multilevel protection
Excellent reliability individually selected cells with acceptance test certificate
Safety multi-sensor active and passive protection systems
Maintenance free standalone electronic control and remote diagnostics
Very long service life stringent choice of cells and components

these are the distinguishing features of Voltmec batteries.

We offer original solutions that allow fast, low-cost retrofitting of new lithium batteries on existing systems as a replacement for lead-acid batteries, whilst maintaining the existing charging system, with excellent performance benefits

COMPONENTS

All components used in our batteries are supplied by leading international manufacturers: cells, sensors, electronic components, contactors, connections and materials are chosen without cost cutting;

We have a test report for EVERY INDIVIDUAL cell used in our batteries;

All this guarantees

VERY LONG SERVICE LIFE

EXCELLENT RELIABILITY

Whatever the application, a single failure more than offsets the savings achieved by using mediocre components!

DESIGN

Batteries are designed entirely in-house, from casing design to control algorithms and from wiring to modules;

The modules used in our batteries are developed in direct partnership with cell manufacturers in order to optimise quality, performance and costs.

Electrical and electronic design and, above all, control algorithms are the result of twenty years’ experience and make our batteries the very best in terms of:

Charge and discharge performance

Efficiency, resulting in reduced energy loss

Safety provided by dozens of sensors and exacting cell selection

MONITORING

Batteries are equipped with a communication system in order to control them and optimise performance by communicating with the power supply unit

A monitoring system using a GPRS SIM card is available and allows

WEB BASED REMOTE MONITORING

It is also possible to utilise all the main industrial and automotive protocols in order to communicate with the battery:

custom protocols based on customer specifications

Sectors

INDUSTRY

Lithium batteries for AGVs, LGVs, cart movers and forklift trucks

Fast charging and high efficiency

Lower charging times: 60 minutes, as little as 10 minutes possible (compared to 6-7 hours for lead-acid); greatly extended mission times.


Charging efficiency exceeding 90%, less wasted energy and lower costs.

No emissions

Sealed, emission-free batteries, safe, free charging in all surroundings.

Maintenance free

No routine maintenance or top-up, lower costs, greater reliability.

Extended battery life

The greater initial outlay quickly repays itself, whilst service life is very long.

Unwavering performance

Solid build ensures nominal performance is maintained even after many years.

Greatly reduced weight

The weight is reduced to a fifth of that of a lead-acid battery, resulting in less wear of the AGV and a higher payload..

ESS and UPS (Energy Storage System, Uninterruptible Power Supply) lithium batteries

Voltage from 48 V to 750 V,

capacity from 20 Ah to 600 Ah and greater

No emissions

Sealed, emission-free batteries, safe, free charging in all surroundings.

Maintenance free

No routine maintenance or top-up, lower costs, greater reliability.

Extended battery life

The greater initial outlay quickly repays itself, whilst service life is very long.

Unwavering performance

More constant capacity ensures nominal performance is maintained even after many years.

Reduced weight and footprint

The weight is reduced to a fifth of that of a lead-acid battery and volume to a third.

VEHICLES

About Voltmec

History

VOLTMEC is an engineering and manufacturing company; a system of ideas, products and services focused on energy and propulsion. From conception and design to manufacture.

VOLTMEC designs, develops prototypes, manufactures and sells battery systems for vehicles and standby applications. It produces and integrates electric propulsion and develops energy and vehicle monitoring systems.

VOLTMEC’s strengths include a solid manufacturing base, as well as the expertise and proven experience of its engineers in areas ranging from the design of electric road vehicle propulsion to standby storage systems and remote terminal units for vehicles and energy.

VOLTMEC’s ideas and innovative skills are the result of more than twenty years’ experience gained by its engineers in the electric mobility sector; from conception and development to the manufacture of hundreds of vehicles and prototypes to be found on the roads.

Battery voltage ranges from 24-96 V (AGV – automated guided vehicle) up to 650-750 V (high performance propulsion, large UPS, marine propulsion).

VOLTMEC can handle small and medium-sized production runs with fast development, delivery and commissioning.
