摘要 |
<p>The invention proposes a method for powering an electric engine (3) of a motor vehicle using a set of battery packs (10, 11, 12, 13) connected in series, at least one of the packs being able, successively, to be excluded from or included in the set powering the engine (3), by means of a switch or a pair of switches (30). While the vehicle is travelling, the switch or pair of switches is controlled in such a way as to limit the output voltage of the battery so that it remains compatible with the vehicle systems or so as to optimise the useful energy of the battery, even if the packs have very different charge states.</p> |
