Estimating the term…
The invention relates to a battery pack type device including a first terminal (101), a second terminal (102) and a plurality of energy storage elements between these terminals, each element including: a) at least one switch for connecting it with, or to disconnect it from, one or more other element(s); b) at least one conductor (15, 17) for conducting a current, parallel to the element, when the latter is not connected with one or more other element(s); c) at least one switch (20) for establishing a short-circuit between the terminals of the battery when the latter is disconnected or supplies a zero voltage; d) a control circuit (30), specifically adapted to: select at least one first energy storage element and at least one second energy storage element, at least one of these elements being to be heated up, to make a current circulate at least from the first element to the second element when the terminals (101, 102) are short-circuited; stop the current when a setpoint temperature for one or more element(s) of the pack is reached.
A battery pack device, comprising:
A method for heating a battery pack type device including a first terminal, a second terminal, and a plurality of energy storage elements between said first terminal and said second terminal, each associated with at least one switch to connect to or disconnect from one or more other of the energy storage elements, the method comprising:
