High precision Coulomb Counter to monitor battery SoC

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.

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 is now part of French Tech

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.

PowerTech Systems attends Hyvolution exhibition on April 4 and 5, 2018

Poissy, April 3, 2018

During two days, the hydrogen storage actors meet during the Hyvolution congress at the Parc Floral in Paris. The event will begin on Wednesday morning with the presentation of a prospective study on France.

PowerTech Systems, will be present at stand 17, with PowiDian, designer of autonomous power stations using renewable energies and hydrogen as fuel.

About PowiDian products

  • MobHylpower

    Presented for the first time at Hyvolution 2018, the Mobhylpower is a generator that uses hydrogen as fuel and can therefore provide mobile electricity without any polluting emissions. It is equipped with the PowerRack® modular Lithium-Ion storage system, now approved by Bureau Veritas Marine & Offshore. It is available in 30kW and soon in a 4kW version.

  • SAGES Station

    The SAGES stations are energy storage stations that mix several technologies (modular Lithium-Ion storage system (LiFePO4) PowerRack®, hydrogen fuel cell…) allowing to meet the needs in electrical storage for many applications (isolated sites, self-consumption) thanks to its technology allowing to use the capacities of each technology to the best of its capacities.

By 2016, 650 people had participated in the first edition of Hyvolution. There are twice as many registered for this second edition, proof that the hydrogen industry is moving forward.
