Founded in Italy’s Motor Valley, Tenax International has become a leading company focused on manufacturing, distributing and supporting ecological street sweepers for cleaning and road hygiene. City councils including Paris, Brussels, Krakow, and Vigo have relied on these solutions, while users as diverse as major campsites, wineries and large factories have chosen Tenax’s electrical machine to care for their own spaces.
The machine, known as the Electra 01, has to provide the same level of autonomy as a diesel solution. Accordingly, Tenax turned to EnerSys as a reliable partner that could consistently supply the battery solutions that they needed. The first request to EnerSys was to provide energy to the sweeper machine for an entire shift of eight hours.
EnerSys responded by performing a careful analysis, verification and elaboration of the new project. Based on this, EnerSys identified a solution based on a 48V 620Ah battery, which guaranteed coverage of an eight-hour shift. This guarantee was backed by an extended warranty period.
Other factors besides the batteries themselves serve to maximise energy efficiency - EnerSys also provided its Life IQ high frequency chargers, together with its Wi-iQ battery monitoring device for checking each battery’s status. The data loggers communicate with the battery chargers and report data in a software package. This information is utilised in optimising charge profiles, extending battery life, reducing charging times, optimising quality, and increasing efficiency.
