Lithium Flash Battery

Flash Battery develops and manufactures custom lithium batteries for industrial machines and vehicles. Depending on the specific application, the desired autonomy and your integration constraints, we will offer you Flash Battery lithium batteries adapted to your needs.

Why choose lithium?

Lithium is the lightest known metal and the least dense solid element with the best electrochemical potential, which offers excellent energy performance and weight control and is therefore used in the manufacture of lithium batteries.
Its very high electrochemical potential (its ability to transfer electrons) makes it a powerful component of lithium batteries.

The security of Flash Battery technology

the 3 key factors of lithium battery safety are:

• Choosing the right chemical formula for lithium batteries
• The type of lithium battery assembly
• The electronics that control the lithium battery

Chemistry: safety is one of the strong points of Flash Battery batteries. Flash Battery uses the safest and most stable chemical formula available on the market, LFP (LiFePO4). It has a very long lifespan: more than 4,000 charge cycles and it is available in large capacity formats (100-200-300 ah), for the industrial systems market.

Assembly: is also essential to ensure the intrinsic safety of the battery, in particular the number of cells in parallel within the battery is the key element. Flash Battery chose to use the prismatic lithium cells because they are more resistant, safe and suitable for medium / large batteries.

Electronics: the real battery brain, the undisputed focal point of Flash Battery, on which the technical and R&D departments are constantly working to ensure maximum innovation. With more than 8,000 batteries sold worldwide, Flash Battery is the best-selling lithium battery in Italy.

The balancing system: how is Flash Battery technology different?

High frequency combined active and passive balancing
Short charging times with balancing time less than 30 minutes
Active support of weaker cells during discharge

Lithium Flash Battery technology means that the cells have different capacities, resistances and self-discharges. This means that when one cell is 100%, another could be 95%. This difference may seem slight, but it can become more and more significant with each cycle and reduce the general level of battery and vehicle autonomy. To avoid this loss of efficiency, the Flash Battery electronics succeeds in standardizing the level of each cell, during charging and discharging.

In a traditional Lithium battery, the control electronics called Battery Management System uses passive low-power systems to carry out balancing, this phase takes 8 to 10 hours without counting the time necessary to replenish the energy, which can vary by battery charger, but can usually be estimated at 3 hours.

The full charge of these traditional batteries can take up to 13 hours and when the balancing is interrupted due to the need for use or intensive use, the gap between the most charged and discharged cells increases, gradually reducing the energy available: vehicles and machines lose a little of their autonomy with each cycle.

The FLASH BALANCING SYSTEM integrated in the Flash Battery acts in active and passive with a much higher balancing power (20A) and not only during charging, but also in active mode during discharge.

This allows balancing 20 times faster, maximum 30 minutes in cyclic applications, which makes it insignificant on the overall charging time.

The “Plus” Efa

Efa France, specialist in vehicle electrification, offers a “charger to wheel” service.

Each of the components of your electric powertrain must be chosen with care so that your vehicle perfectly meets your needs.

Batteries and chargers are no exception: with our partners, we define them precisely to guarantee their good communication with the other components, and to obtain the expected performance (recharge time, autonomy, peak power, duty cycle, etc.).
