Abstract

An uncertified battery replacement countermeasure apparatus for an electric vehicle including a power source that is driven by an electric power from a replaceable battery, in which it is judged whether or not a post-replacement battery is a battery certified to the electric vehicle, and when it is judged that the post-replacement battery is not the battery certified to the electric vehicle, a power output of the power source is restricted while permitting driving of the power source.

Claims

1. An uncertified battery replacement countermeasure apparatus for an electric vehicle including an electric motor as at least a part of a power source which is driven by an electric power from a replaceable battery, in which the electric vehicle comprises an electric auxiliary equipment that is actuated by an auxiliary power source provided separately from the battery, the auxiliary power source being charged with an electric power from the battery, and when the auxiliary power source is in a non-chargeable state, the power output of the power source is restricted in accordance with a reduction of a capacity of the auxiliary power source, the uncertified battery replacement countermeasure apparatus comprising:

A controller comprising a battery propriety judgment section configured to judge whether a post-replacement battery is a battery certified to the electric vehicle or a battery uncertified to the electric vehicle; and

a power output restricting section configured to restrict a power output of the power source while permitting driving of the power source when it is judged that the post-replacement battery is the battery uncertified to the electric vehicle by the battery propriety judgment section,

wherein the power output restricting section is configured to apply a specific configuration of power source output restriction corresponding to the reduction of a capacity of the auxiliary power source among configurations of power source output restriction corresponding to the reduction of capacity of the auxiliary power source.

2. The uncertified battery replacement countermeasure apparatus for an electric vehicle as claimed in claim 1, wherein the battery propriety judgment section is configured to judge whether the post-replacement battery is the battery certified to the electric vehicle or the battery uncertified to the electric vehicle by referring an identification code attached to an individual battery to a predetermined identification code.

3. The uncertified battery replacement countermeasure apparatus for an electric vehicle as claimed in claim 2, wherein the power output restricting section is configured to execute the output restriction such that a ground speed of the electric vehicle is suppressed.

4. The uncertified battery replacement countermeasure apparatus for an electric vehicle as claimed in claim 1, wherein the power output restricting section is configured to execute the output restriction such that a ground speed of the electric vehicle is suppressed.

5. The uncertified battery replacement countermeasure apparatus for an electric vehicle as claimed in claim 4, in which the electric vehicle comprises an electric auxiliary equipment that is actuated by an auxiliary power source provided separately from the battery, the auxiliary power source being charged with an electric power from the battery, and when the battery is in a defective condition, the ground speed of the electric vehicle is restricted in accordance with a reduction of a capacity of the auxiliary power source,

wherein the power output restricting section is configured to apply a specific configuration of ground speed restriction corresponding to the reduction of a capacity of the auxiliary power source among configurations of ground speed restriction corresponding to the reduction of capacity of the auxiliary power source.

6. An uncertified battery replacement countermeasure apparatus for an electric vehicle including an electric motor as at least a part of a power source which is driven by an electric power from a replaceable battery, in which the electric vehicle comprises an electric auxiliary equipment that is actuated by an auxiliary power source provided separately from the battery, the auxiliary power source being charged with an electric power from the battery, and when the auxiliary power source is in a non-chargeable state, the power output of the power source is restricted in accordance with a reduction of a capacity of the auxiliary power source, the uncertified battery replacement countermeasure apparatus comprising:

a controller configured to;

judge whether a post-replacement battery is a battery certified to the electric vehicle or a battery uncertified to the electric vehicle;

restrict a power output of the power source while permitting driving of the power source when it is judged that the post-replacement battery is the battery uncertified to the electric vehicle; and

apply a specific configuration of power source output restriction corresponding to the reduction of a capacity of the auxiliary power source among configurations of power source output restriction corresponding to the reduction of capacity of the auxiliary power source.
