Regeneration capacity The very first steps in energy regeneration were made on the i-StARS GEN2 for the Serena S-Hybrid 2012, though the recovery rate was limited by the operating voltage and battery type, much higher levels can be attained starting with the i-StARS GEN3 and the upcoming Valeo 48Volts e-machines. What’s more with i-StARS? Engine-Off coasting and reflex start Engine-Off coasting is the ability while driving to: 1-Switch the gearbox to neutral when no engine torque is required 2- Stop the engine , the unique mechanical energy source being at that time the vehicle kinetic energy 3-Drive the vehicle in freewheeling conditions up to a standstill state.

i-StARS's power electronics improve the system's electrical efficiency to make it one of the most efficient alternators on the market. ●● i-StARS solution is lighter ●● i-StARS connectivity is comparable to the one of an alternator ●● Electronics continuous operating temperature capability is +25% higher ●● i-StARS is scalable up to 3 kW ●● i-StARS benefits from and increased torque capability ●● Best in class alternator efficiency thanks to synchronous rectification ●● Thermal management for higher peak torque output ●● Durability: 600,000 restarts

i-StARS provides complementary services to its predecessor StARS

Boost /Torque assist

Valeo offers a torque assist option on i-StARS, this feature was first applied on the Nissan Serena S-Hybrid 2012 , for the Asian market, delivering some torque assist for a short duration when driving from standstill.

This feature is offered since the i-StARS GEN2.
