Poissy – July, 5th, 2018


The French manufacturer PowerTech Systems obtains the Type Approval marine certification. This for its scalable Energy Storage System product line: PowerRack®.

Press release: July 5th, 2018


The Lithium-Ion storage system is designed for electric traction in marine applications.

PowerRack® product line has been approved by the Bureau Veritas Marine and Offshore. This actor in maritime field is the world leader player in testing, inspection, certification services.

The «Type Approval» certification opens up possibilities. Indeed, the PowerRack® product line can now be used in a huge variety of hybrid and 100% electric propulsion systems for marine applications.

As a use case, PowerRack®system will be set up in 2018 on-board a 100% electric restaurant boat (Michelin-starred restaurant). It is based at the foot of Eiffel Tower. This boat will operate on the Seine river. It will use stored energy in its batteries to power the electric motors and supplies energy on board.

The modular and scalable PowerRack® system offers the possibility to set-up all kind of energy storage configuration. That is to say from 2.56 kWh to 1MWh with a voltage ranging from 51,2V to 921,6V. The PowerRack® product-line is equipped with an innovating system called “BMS-Matrix®”. It allows full control and total safety of operation.

100% compliant

In order to get this marine certification, PowerTech Systems carried out a complete series of tests (safety tests, vibration and environment tests, resistance to severe environments, etc). These tests ensure our customers that our products are rated with high level of safety and reliability for marine applications.

The «Type Approval» certification covers the whole of the lawful, technical and safety requirements. These ones are defined by Bureau Veritas Marine and Offshore for the type “Steel Ship” with passenger’s transportation.

PowerTech Systems is proud for obtaining the «Type Approval» certification for our PowerRack® energy storage system.

This French-made product offers the possibility to ramp-up green energy adoption. It could be used for large transport vehicles. Such as the river or commercial vessels which is an important source of gas for greenhouse effects.

This storage solution for green energy is all the more relevant as it replaces the diesel groups on vessels. These latters often transit or operate in the middle of our city-centers. , Cyril Bergeaud, Founder and CEO.

Hydrogen mobile electricity generator MobHylpower

Poissy, June 26, 2018

PowerTech Systems is proud to participate in this event through its partnership with PowiDian and its 30 kW hydrogen generator set, the MobHylpower M30.
The latter is equipped with PowerBrick+® batteries and the modular Lithium-Ion Iron Phosphate (LiFePO4) PowerRack® storage system, approved by Bureau Veritas Marine and Offshore.

Applause for the PowiDian company that developed the “MobHylPower“, a mobile, silent and non-polluting electricity generator. It is supplied by hydrogen cylinders (type B20 or B50) and can be transported on land with limited access or in confined spaces.

It was a success! The generator provided clean energy throughout the event (from 16h to midnight), capable of managing a wide load range (from 1kW to 25kW).

Quick facts :
PowiDian offers two “zero emission” generator set power ranges: the “S4” with a power of 4 kVA and the “M30” with a power of 30 kVa.
Solutions that allow a number of start/stop times and an equivalent or even longer service life than generators in the same power range.

High precision Coulomb Counter to monitor battery SoC

Coulomb counter CC75 CC150 CC500

MyLithiumBattery extends its range of accessories with new charge indicators, including the CC75, CC150, CC500 coulomb counter

Poissy, May 29, 2018

High accuracy measurements of voltage (V), capacity (Ah), power (W) and battery energy

CC75, CC150, CC500 Coulomb Counters from MyLithiumBattery.com allow the user to obtain a state of charge in % (SoC – State Of Charge), and a precise depth of discharge (DoD) of the battery. They also calculate, in real time, the time remaining before the battery is completely empty.

Coulomb-Counter-C150-shuntCoulomb-Counter-C150-shunt
Coulomb-Counter-C150-shunt-resistorCoulomb-Counter-C150-shunt-resistor

The CC 75/150/500 are suitable for batteries with an operating voltage from 8V to 80V DC.
There are 3 versions :

  • CC75 measuring from 0 to 75A, compatible with M6 terminals
  • CC150 measuring from 0 to 150A, compatible with M8 terminals
  • CC500 measuring from 0 to 500A, compatible with M10 terminals

For applications using batteries, the situation is often critical if users are suddenly without energy (for example electric bicycles, security cameras, alarms, IoT, on-board sensors…).
In these cases, the accuracy of a Coulomb Counter for batteries State of Charge measurement is a “must have”.

Rely on CC75, CC150, CC500 coulombs counters

Simply measuring a voltage at the terminals of a battery is not enough to know its precise state of charge (SoC).

With our CC75/150/500, the advantage is real and allows precise counting of coulombs to determine their state of charge, as well as a measurement of the battery voltage and the instantaneous current used. This information is used to monitor the charge status of the system with battery.

Coulomb Counter allows accurate SoC nformation that can be communicated onto a bus network (CAN, TTL232, RS232).

Once the counter is initialized, it counts the coulombs used for a discharge, and those generated by a charger in order to take partial charges into account.

This principle has the advantage of being compatible with all battery technologies (lithium-iron-phosphate (LiFePO4), lithium-ion, Li-Polymer, lead-acid and nickel-metal hybrid batteries…).

PowerTech Systems joins French Tech community

Poissy, April 17, 2018

The French manufacturer PowerTech Systems, specialized in the design of Lithium-Ion energy storage systems, integrates the “French Tech” movement, the ecosystem of French start-ups in France and internationally.

French Tech” refers to all those who work in or for French start-ups in France or abroad. Convinced that it is necessary to encourage the emergence of successful start-ups in France to generate innovation, economic value and new jobs, the Government created this initiative in 2013.

The principle is simple: to rely on the initiatives of the French Tech members themselves, to enhance what already exists, to make the brand grow and evolve.

In turn, PowerTech Systems is committed to participating in this collective initiative. PowerTech Systems now carries high, a common standard for both French Tech members and the state that supports innovative companies.

The French Tech value is to be built collectively with all French actors (public actors, media, general public, large groups, research institutes, associations, etc…).

We are very proud to participate in this initiative, which highlights the innovation, technicality and expertise of our technicians and engineers on our territory. Joining this movement is also a way for us to highlight the quality of our scientific and technical training, as well as the enthusiasm of our employees to constantly innovate.
