For aeronautics use, it is imperative to use rechargeable batteries allowing to have the maximum of energy for the minimum mass. Today, it is the Lithium - Polymer technology (or "Li-Po") that presents the best specific energy.
ELECTRAVIA has chosen KOKAM Lithium-Polymer cells. KOKAM is the world leader of such batteries.
REALIZATION OF CUSTOMIZED LI-PO BATTERIES
Since 2009, ELECTRAVIA proposes its expertise for the realization of customized Li-Po batteries:
= > studies of integrated Li-Po batteries with electronics of control, balancing, display and recording of parameters
= > integration of every packs of batteries Li-Po on the basis of KOKAM cells : see catalog KOKAM
= > conception and realization of the electronics of surveillance and balancing of Li-Po cells :
* BMS (Battery Management System), managing the load and the discharge of the battery
* PCM (Protection Circuit Modulates), modulates connected to every cell checking permanently its voltage
* Equalizer of every cell
These circuits are made customized according to the cells and the use of batteries.
= > conception and realization of the communication's protocols
= > manufacturing of the dedicated instrumentation
=> conception and realization of specific packaging for the cells
= > selection or realization of dedicated chargers. The load of Li-Po cells is made in constant intensity until obtain a tension of 4,2V by cell, then it continues in constant voltage until the intensity of load passes below c / 20. For the industrial Li-Po cells, the load can intervene at once after use. For example, the complete refill of a battery Li-Po of 3kWh sets 1:30. Li-Po batteries are useful immediately after refill.
