E-Waste Silistra EAD EAD (jsc.) holds a permit for annual treatment of used batteries from electric vehicles with a total capacity of 18 thousand tons. The activity takes place in the industrial zone of the town of Silistra.
E-Waste, in cooperation with academic partners as well as industrial integrators and companies for building and management of photovoltaic solar systems for industrial and domestic purposes, has set up a solution for electricity storage by re-configuring used lithium-ion battery modules from electric vehicles. The solution is tailor made to match the specific individual capacity needs of our clients.read more
The process of transformation of used lithium batteries into stationary electrical energy storage systems comprises the following basic steps:
the battery systems (or modules) of the main components: lithium-ion cells, metal housing, metal bars that hold the individual cells; copper conductors in the form of cables and busbars; electronic components and boards to provide charge and discharge control at cell level.
each individual lithium-ion residual cell, if necessary, with (with an additional charging device supporting adequate charging curve technology and current and voltage levels) rescue / training cycles to increase capacity and improve the performance of the cell.
of several lithium-ion cells (with the same or very similar residual capacities (state of health) ) depending on the expected operating voltage and current of the module, followed by a BMS to manage the cell group (module).
a power storage system consisting of a metal housing (slots box) with rails to guide the individual elements in which the lithium-ion modules are connected and arranged, which are controlled by electronic circuits, charging controllers, inverters converting DC power into AC and interface to perform configuration and display of performance - user display.
