A bidirectional battery charge control system for a portable electronic device that uses a rechargeable main battery. The system enables the connection of an auxiliary battery (16) to the device for inputting additional current to the device. A bidirectional charger (22) performs control of the current flow into and out of the auxiliary battery. The auxiliary battery can contain one or more readily available primary or secondary cells, and the bidirectional charger is such that an external charger connected to the device, generally used to charge the main rechargeable battery of the device, can also recharge a secondary cell or cells in the auxiliary battery, if such are installed. The use of such an auxiliary battery enables the main battery to be hard-wired into the device.

L'invention porte sur un système de contrôle bidirectionnel de charge de batterie d'un dispositif électronique portable qui utilise une batterie principale rechargeable. Le système permet le raccordement d'une batterie auxiliaire au dispositif de façon à envoyer à ce dispositif un courant additionnel. Le contrôle de l'arrivée et de la sortie du courant de la batterie auxiliaire s'effectue par un chargeur bidirectionnel. La batterie auxiliaire peut contenir un ou plusieurs éléments primaires ou secondaires facilement disponibles, et le chargeur bidirectionnel est généralement utilisé, tel qu'un chargeur externe raccordé au dispositif, pour charger la batterie principale rechargeable du dispositif, et permet également de recharger un ou des éléments secondaires de la batterie auxiliaire, s'ils sont installés de cette façon. L'utilisation de cette batterie auxiliaire permet de câbler la batterie principale au dispositif.
