1. A method for managing an electric or hybrid vehicle comprising at least one rechargeable electrical energy storage module, each storage module comprising one or more Lithium-Metal-Polymer batteries and being arranged in order to:
- provide a high-voltage electrical supply signal for driving said vehicle; and
be maintained at a temperature, called operating temperature, by a heating means;
said method comprising;
before a prolonged period of non-use of said vehicle, a phase, called winterizing phase, comprising a step of cooling each storage module in order to reach a predetermined temperature, lower than said operating temperature; and
following a prolonged period of non-use of said vehicle, a phase, called dewinterizing phase, comprising a step of heating each storage module in order to reach an operating temperature comprised between 60°
C. and 80°
