TRACTION BATTERY REGENERATION

Your company works with forklifts, electric trolleys, cranes or, for example, a tourist vehicle?
In that case, you certainly encounter problems with charging the batteries powering your equipment.

Nowadays, when working in two or three shifts is unavoidable, the equipment drains the batteries quickly and needs to be supplemented constantly. With time, of course, this impairs the batteries’ capacity and shortens their life cycle.

IN ONLY ONE WEEK, AN INDUSTRIAL BATTERY UNDERGOES ABOUT 7 CHARGE CYCLES

Frequent charging and discharging causes the batteries to lose their capacity more quickly, and thus need to be charged more often. For the sake of comparison, the same happens to your cell phone’s battery. In the beginning, when it is still not “worn out”, you can use it for several days, but after it has been charged and discharged multiple times, it simply does not work as you would like it to.

Imagine being able to improve your traction battery performance by renewing their capacity, and save money at the same time!

Sounds impossible?
Not any more!

Imagine being able to significantly reduce electricity costs of charging traction batteries.

It is possible now!

Imagine being able to foresee the need for battery or charger servicing, that is, having a tool which facilitates your budgeting for the following period!

WE HAVE DEVELOPED AN OPTIMIZED TRACTION BATTERY CHARGING (OBC) SYSTEM

Having been involved in battery regeneration activities for years, we have noticed that the market lacks a product that would systematically monitor and manage the charging of different types of batteries.

We took the matter into our own hands and developed the OBC system for monitoring and managing battery charging!

Used properly, the OBC system can extend your batteries life cycle by 50 - 100 % and reduce charging costs by 50 %, while at the same time ensuring a return on your investment in a very short time!

THE INNOVATIVE OBC SYSTEM CONSISTS OF

MEASUREMENT UNITS - Micro controller devices for monitoring the charging of traction batteries.

CONTROL UNIT – A unit of the local measurement units network for charging stations and for connecting to the main control computer. The control unit can receive up to 64 measurement units, meaning one system can monitor and manage the work of a total of 64 chargers in real time.

SOFTWARE – The programme enabling remote control of charger operation and the monitoring of traction battery status. The software is located on the main control computer connected to the control unit. It works as an application displaying and analysing collected data, and it can also be used to create charging characteristics for the particular type of battery, to plan battery charging and undertake actions for maintaining chargers and batteries.

HOW DOES THE SYSTEM WORK IN PRACTICE?

The charging voltage and battery charging current on the serial resistor are measured by digital measurement units (1).

The data obtained are actually average data in 10-second intervals. Data are stored on an internal storage medium, enabling a high level of data collection subsystem autonomy.

Each measurement unit has its own real time clock (RTC) that records dates and the time of beginning and end of battery charging.

The time is set and adjusted through the control unit. The developed measurement unit can also be used in high-frequency chargers (2). This additionally increases the cost-effectiveness of the investment into system development and the scope of its commercial application. The control unit connects to the main control computer containing the database stored in the developed software. In the opposite direction, the control units and charger operation are controlled through this computer (3).

Measurement units are installed into the existing chargers in the charging stations or at the individual location for charging batteries.

MAIN OBC SYSTEM FUNCTIONS

supplementary charging of the batteries up to maximum capacity
monitoring the charging in real time
reducing electric power costs
controlling the duration of supplementary charging
desulfation control
detecting malfunctions
extending the life cycle of traction batteries

OBC systems are appropriate for use in traction battery charging stations in logistics centres, industrial plants, and in all industries where electric-powered forklifts, machinery and vehicles are used. The installed capacity of distribution and logistics centres with as little as 50 batteries is equal to that of a small power plant. That is why you need a tool that helps you monitor and manage your charging processes!

DO YOU NEED AN OBC TRACTION BATTERY CHARGING SYSTEM?

If you need to charge several pieces of industrial batteries frequently, the OBC system is an excellent solution for saving energy, reducing maintenance costs, extending battery life and doing business more cost-efficiently.

REWARDS

At the end of last year, we had the opportunity to be part of the 44th Croatian Innovation Salon with international participation - INOVE 2019 and 15th Exhibition of Innovations, Prototypes and Student Business Plans - BE A SAMPLE 2019 at which we introduced ourselves with our OBC system for optimized battery charging. The international judge panel recognized the value and success of our project and we won no less than a silver medal!
