All models in Renault Z.E range have the high-performance and enduring lithium-ion battery. Lithium-ion battery technology is currently the most efficient on the market: its high energy density can store a maximum of KWh per kg for optimized battery life. Recharging is very easy, with the ability to charge the battery even when it is not completely discharged. In an electric vehicle, the battery acts as an energy reservoir. The architectural design of the battery depends on the type of vehicle for which it is intended. For example, the Fluence ZE battery comprises 48 power modules, each consisting of four elementary cells. It is in the interior of these cells that the electrochemical reactions take place to produce power or store energy. The Lithium-ion battery fitted to the models of the Renault ZE range is recyclable when dead.
