Method for determining the operating state of a battery and battery implementing such a method

A method for determining an operating state of a battery with respect to one or more use profiles, comprising:

• defining, for the one or more use profiles, operational limits inside of a memory of said battery depending on parameters of the battery comprising a temperature, a level of charge of the battery, and one or more ageing parameters of the battery, wherein said operational limits delimit an operational zone in which the battery carries out the one or more use profiles and a non-operational zone in which the battery does not carry out the one or more use profiles, wherein the operational limits are defined by implementing tests for each of the one or more use profiles by checking whether the battery is capable of providing the use profile in a temperature range, in a level of charge range, and in an ageing parameter range;
• determining the operating state of the battery for a given one of the one or more use profiles based upon determining the parameters with a calculator integrated into the battery;
• comparing the operational limits and the parameters of the battery with the calculator;
• analyzing one or more of the parameters;
• and
• adjusting the temperature or a level of charge of the battery to return the battery to the operational zone.
