Abstract
A method of controlling a supercapacitor energy storage unit (), included in a motor vehicle micro-hybrid system, is disclosed. The storage unit is suitable for performing the functions of an alternator, starter and automatic stop-restart of the vehicle heat engine, regenerative braking and torque assistance. The energy storage unit () is a plurality of supercapacitor elementary cells connected in series (Cto C) and capable of delivering information (Vmax, Temp and DeltaV) on its internal status. The method includes various stages of: comparing a maximum elementary voltage (Vmax) with a first voltage threshold (Vmax); comparing a temperature (Temp) with at least one temperature threshold (ST=55° C., ST=65° C. and ST=70° C.); and, deciding on limitations of the availability of functions of the unit when the (Vmax) information reaches threshold (Vmax) for a predetermined duration (T) and/or when the (Temp) information reaches the temperature threshold (ST=55° C., ST=65° C. and ST=70° C.).
