Charge control device for batteries
First Claim
1. A charge control device designed to execute charge control for a battery by controlling an output power of a power generator for a vehicle, the charge control device comprising:
- a nonvolatile memory configured to store therein a control program and control data required to execute the charge control for the battery;
a rewriting unit configured to rewrite a content of the nonvolatile memory based on information inputted from an external device; and
a communication circuit that is connected to the external device upon rewrite of the content of the nonvolatile memory by the rewriting unit so that the external device and another device installed in the vehicle are selectively connected to each other,wherein selection of any of the external device and the other device to which the communication circuit is to be connected is performed by connection of the communication circuit to any of the external device and the other device via a communication line.

Abstract
In a charge control device installable in a motor vehicle and designed to execute charge control for a battery based on an output power of a power generator, a nonvolatile memory stores therein data required to execute the charge control for the battery. A communication circuit is communicably connectable to first and second devices different from each other. The first device allows entrance of information required to rewrite the data stored in the nonvolatile memory. A rewriting unit rewrites the data stored in the nonvolatile memory based on the entered information only when the first device is communicably connected to the communication circuit.
