For highest demands in industrial applications

Lithium-titanate – technology of a new standardBenefit from unprecedented cell qualities

With 15,000 charging and discharging cycles the lithium-titanate cell LecCellis particularly suitable for long-term investment and low-maintenance storagesystems. The costs for maintenance and exchange are minimal and shorten thereturn on investment period.

15,000 full cycles

The heart of any storage device is the cell. Its quality determines the performance of the entire storage system. Cells provided with a lithium-titanate anode are vastly superior to conventional lithium-ions with regard to capacity, service life and load cycles.

The quality of the cell permits a stable current of 4C. Thus a cell is chargedor discharged within 15 min.

Permanent charging/discharging rate of up to 4C

The possible Depth of Discharge of LecCell of 100% considerably increasesthe effi ciency of the storage system. The depth of discharge persists over the15,000 charge/discharge life of the cells.

100% DoD (= Depth of Discharge)

The service life of the cell is not infl uenced by the operation of the cell ina specifi c SOC (= State Of Charge) range. Whether primarily in a range of30% SOC or 60% SOC: The service life is entirely independent of the SOC.

Stable operating range on any SOC level

As the only manufacturer worldwide Leclanché avoids using ecologicallydamaging solvents in electrode manufacturing and using water based method.This method is environmentally friendly and prolongs the service life of the cell.

Water-based cell manufacturing

• Wide temperature range for operating the cell• CE and UN 38.8 tested by TÜV Rheinland• Individual ID for each cell for tracking the manufacturing

process• Continued internal and external tests

Innovative Technology – quantifiable added value in the fieldProfit from our sound partnership with ads-tec

Leclanché energy storage systems are individuallydesigned, developed and produced accordingto the customers‘ requirements. Depending on the specific demand and application alternative cell technologies are used. The integration of the storage system into existing systems is possible without problems owing to the use of prevailing industry

Flexibility

The heart of any storage device is the cell. Its quality determines the performance of the entire storage system. Cells provided with a lithium-titanate anode are vastly superior to conventional lithium-ions with regard to capacity, service life and load cycles.

Maximum safety – of the cell, module and storage systemExperience permanent, secure operation

Safety ranks first at Leclanché: with regard tothe operation of the storage system,the connected components as well as the system itself.

• From a chemical point of view the lithium-titanate cell is one of the safest lithium-based cells

• It has an exceptionally high tolerance against overcharging

• The patented ceramic separator of LecCell prevents thermal runaway or a short circuit in the cell

• Hazardous gas formation which might widen the cell or make it burst is excluded in LecCell

• Internally or externally induced mechanical damage has no impact on the safety of the system

Cell level

• Tracing of the temperature, voltage and current of each cell by continuous monitoring

• Module voltage below 60 VDC• Each module is additionally equipped with a

separate hardware protection.

Module level

• Module voltage (DC) of less than 1000 VDC• The galvanic separation is effected on the BMS

level, between communication and battery• The compliance with all current and future

standards is continuously monitored for cells, modules and storage system

• Every string is secured by a string box• A fire protection system may be integrated

New perspectives – versatile solutions as an alternativeRely on upgradable and flexible concepts

• Proportional supply of dynamic loads from storage• Fixed or dynamic limiting of the power consumption

Limiting the power consumption from the public grid

• With the help of the storage, the power fed into the grid can be limited according to a dynamic trend or by a fixed value. In this way, feed-in directives can be satisfied or personal

Limiting the feed-in power into the public grid

• The self-produced energy is distributed over time with the aid of the storage system in such a way that the desired percentage of produced energy is directly consumed by oneself and is not fed back into the grid

Optimisation of personal consumption

• The storage serves to cover the load curve of the connected loads with the specified self-sufficiency rate from self-produced and stored energy

• Black start capacity and network formation by the systemIsolated function

• Online UPS supply of consumers in the event of power failureUPS
