New version of PowerModule (v2) launched !

PowerTech is pleased to announce the launch of the new version of the PowerModule modular battery system. This product completes the PowerRack range for medium to high power applications.

PowerModule by PowerTech Systems

The design of the product has been engineered to reduce space requirements and facilitate integration.
The vertical and horizontal assembly of the modules allows a large number of combinations and meets a maximum of needs (Vehicles, marine, industrial machinery, rail, robotics, etc.)

New PowerBrick® version with new generation cell

Our PowerBrick® product range is expanding with 4 new versions using our new generation LiFePO4 lithium cells.

As a reminder, all our products now use the new generation cell which ensures a better service life (3000 cycles at 100% DoD at 1C, 4500 cycles at 80% DoD at 1C) and an increased energy density of +25%.

The PowerBrick 12V-30Ah makes its entry using the PowerBrick 12V-20Ah enclosure, i. e. an energy density increased by +50% in the same enclosure
The PowerBrick 12V-45Ah complements the 12V-40Ah version by using the same box (+12.5% more energy)
PowerBrick 12V-70Ah uses the same housing as the PowerBrick 12V-55Ah (+27% more energy)
Ditto for the PowerBrick 48V-72Ah which takes over the case of the 48V-61Ah version (+18% more capacity)

All previous ranges are preserved, and all now equipped with our new generation cell.

New high-performance lithium LiFePO4 cells

Lithium Iron Phosphate - LFP - LiFePO4-cell

After more than a year of intensive testing, we are now using a new high-performance lithium LiFePO4 cells to replace the cells used in our products.

This new generation of cell retains all the safety and robustness of those used in our products to date and adds two major improvements:

  • Specific Energy improved by 25% : It is possible to accommodate 1/4 more energy in the same volume.
  • Improved operation life by 50% : Cycling tests performed show a performance of 3000 cycles of full charge-discharge cycles (100% depth of discharge) at 1C. This represents a 50% increase in the number of cycles compared to the previous generation.
    At a DoD of 80% at 1C, the number of cycles performed rises to 4500.

Below chart shows the estimated number of cycles for our new generation of Lithium LiFePO4 cells, according to the discharge power and DOD figures. The test conditions are those of a laboratory (constant temperature of 25°C, constant charge and discharge power).

Lithium Iron Phosphate Life Cycle
Life Cycle chart of new LiFePO4 cell generation

We can read from the chart the below figures :

  • 3 000 cycles at 100% DoD @ 1C
  • 4 500 cycles at 80% DoD @ 1C
  • 10 000 cycles at 60% DoD @ 1C
  • etc.

It should be noted that following the number of completed cycles, the cell still have a nominal capacity > 80% of the original capacity.

Our main product ranges: PowerBrick, PowerRack and PowerModule, will benefit in the coming months from this new generation of cells with an increase in capacity, a reduction in weight but also a significantly improved lifespan.

World premiere: “Ducasse sur Seine”, the first 100% Electric Michelin Starred restaurant boat, equipped with the PowerRack battery system

Ducasse sur Seine electric boat - PowerRack
Ducasse sur Seine – PowerRack

PowerTech Systems is pleased to announce that it is equipping the “Ducasse sur Seine”, 100% electric boat with its  PowerRack®  modular lithium battery system.

This 100% electric boat (propulsion, on-board equipment, kitchens, etc.) is powered entirely by our Lithium Iron Phosphate batteries, representing a stored energy of 720 kWh divided into two totally independent PowerRack banks.

The PowerRack battery system, certified by Bureau Veritas in early 2018, consists of 24 cabinets of 30kWh in 700V DC, connected in parallel. These batteries represent a weight of about 9 tons on board. This cabinet system limits floor space and allows energy to be stacked over the entire height of the hull, making the installation compact and integrated into the boat.

The “Ducasse sur Seine” has been in production since September 10, 2018. It delights the taste buds of its passengers twice a day (lunch and dinner), every day of the week. The trip to the heart of Paris is done without vibrations, silently, and without any pollution.

The official inauguration of the new vessel took place on 25 September 2018 in the presence of Mrs Anne Hidalgo, Mayor of Paris, and other personalities.

New products : PowerBrick+ 48V-61Ah and PowerBrick+ 12V-250Ah

PowerBrick-61Ah-48V-and-250Ah-12V

Poissy, April 4, 2018

PowerTech Systems, a manufacturer of innovative energy storage systems specializing in Lithium-ion Iron Phosphate (LiFePO4) technologies, is expanding its PowerBrick+ product line and introduces two new batteries: PowerBrick+ 48V-61Ah and PowerBrick+ 12V-250Ah.
