Patent Images
1. A method to manage charge of a rechargeable battery comprising at least one electrochemical cell having a predetermined maximum continuous charge current (IMR_C) allowed for given temperature and state of charge conditions, the method comprising the steps of:
- measuring an instantaneous charge current (I);
defining an overcharge capacity (Cap)-determining an instantaneous maximum current allowed in charge (IMR) as a function of the overcharge capacity.

Abstract
A method to manage charge and/or discharge of a rechargeable battery comprising at least one electrochemical cell having predetermined maximum continuous charge current (IMR_C) and/or discharge current (IMD_C) allowed, the method comprising the steps of:
- measuring an instantaneous charge current (I);
- defining an overcharge capacity (Cap);
- determining an instantaneous maximum current allowed in charge (IMR) as a function of the overcharge capacity; and/or
- defining an over thermal capacity (CapTh);
- determining an instantaneous maximum pulse current allowed in discharge (IMD_max) as a function of the over thermal capacity.
