Abstract

This control apparatus includes (A) a first connecting part, which is connected with a driving control apparatus for controlling driving of a power unit for assisting a human power or with the power unit, and through which a current relating to charging and discharging of an electrical power storage device flows, (B) a second connecting part, which is provided separately from the first connecting part, and through which a current relating to charging to the electrical power storage device flows via an electrical connection, and (C) a controller to control charging and discharging of the electrical power storage device, which are performed by using a current, which flows in the first connecting part and/or the second connecting part.

First claim

What is claimed is:

1. A control apparatus, comprising:
a first connecting terminal, which is connected with a driving control circuit for controlling driving of a power circuit for assisting a human power or with the power circuit, and through which a current relating to charging and discharging of an electrical power storage device flows;
a second connecting terminal, which is provided separately from the first connecting terminal, and through which a current relating to charging to the electrical power storage device flows via an electrical connection; and
a controller configured to switch charging modes according to states in the electrical power storage device,
wherein the controller is configured to perform the charging to the electrical power storage device in a first charging mode, upon detecting a first state in the electrical power storage device where a value of a current or electrical power relating to the charging to the electrical power storage device is limited to a value less than a maximum value defined for the electrical power storage device, and to perform the charging to the electrical power storage device in a second charging mode, upon detecting a second state in the electrical power storage device where the value of the current or electrical power relating to the charging to the electrical power storage device is allowed to be the maximum value, and
in the first charging mode, the controller is configured to suppress or stop charging by a second current or electrical power that is supplied from the second connecting terminal and relates to the charging to the electrical power storage device and to put priority on charging by a first current or electrical power that is supplied from the first connecting terminal and relates to the charging to the electrical power storage device, even when the second current or electrical power is detected, or even when the charging from the second connecting terminal is instructed, and
in the second charging mode, the controller is configured to control the charging to the electrical power storage device so that a sum of a value of the first current or electrical power and a value of the second current or electrical power is equal to or less than the maximum value, when the second current or electrical power is detected, or when the charging from the second connecting terminal is instructed.

2. The control apparatus as set forth in claim 1 , further comprising a third connecting terminal, which is provided separately from the first connecting terminal, and through which a current relating to discharging of the electrical power storage device flows via a second electrical connection,
wherein the controller is configured to control outputs by putting priority on a third current or electrical power among the third current or electrical power and a fourth current or electrical power, wherein the third current or electrical power is outputted to the first connecting terminal and relates to the discharging of the electrical power storage device, and the fourth current or electrical power is outputted to the third connecting terminal and relates to the discharging of the electrical power storage device.

3. The control apparatus as set forth in claim 2 ,
further comprising a fourth connecting terminal, which is provided separately from the first connecting terminal, and through which data output is performed,
wherein the controller is configured to output, through the fourth connecting terminal, an amount of current or electrical power, which has been outputted through the third connecting terminal.

4. The control apparatus as set forth in claim 2 ,
further comprising a fifth connecting terminal, which is provided separately from the first connecting terminal, and through which data input and/or output is performed with wired or wireless, wherein the controller is configured to output, through the fifth connecting terminal, an amount of current or electrical power, which has been charged through the second connecting terminal, when requested through the fifth connecting terminal.

5. The control apparatus as set forth in claim 2 ,
further comprising a fifth connecting terminal, which is provided separately from the first connecting terminal, and through which data input and/or output is performed with wired or wireless, wherein the controller is configured to output, through the fifth connecting terminal, an amount of current or electrical power, which has been outputted through the third connecting terminal, when requested through the fifth connecting terminal.

6. The control apparatus as set forth in claim 1 ,
further comprising a third connecting terminal, which is provided separately from the first connecting terminal, and through which a current relating to discharging of the electrical power storage device flows via a second electrical connection,
wherein the controller is configured to control the discharging of the electrical power storage device so that a sum of a value of a third current or electrical power and a value of a fourth current or electrical power is equal to or less than a first predetermined value, or so that a sum of a ratio of the value of the third current or electrical power to a certain constant value and a ratio of the value of the fourth current or electrical power to the certain constant value is equal to or less than a second predetermined value, wherein the third current or electrical power is outputted to the first connecting terminal and relates to the discharging of the electrical power storage device, and the fourth current or electrical power is outputted to the third connecting terminal and relates to the discharging of the electrical power storage device.

7. The control apparatus as set forth in claim 1 ,
further comprising a third connecting terminal, which is provided separately from the first connecting terminal, and through which a current relating to discharging of the electrical power storage device flows via a second electrical connection,
wherein the controller is configured to suppress a value of a current or electrical power, which is outputted to the first connecting terminal and relates to the discharging of the electrical power storage device, when a current or electrical power output through the third connecting terminal is requested.

8. The control apparatus as set forth in claim 1 ,
further comprising a third connecting terminal, which is provided separately from the first connecting terminal, and through which a current relating to discharging of the electrical power storage device flows via a second electrical connection,
wherein, in a state in the electrical power storage device where a value of a current or electrical power relating to the discharging of the electrical power storage device is limited to a value less than a second maximum value defined for the electrical power storage device, the controller is configured to suppress or drop to zero a value of a current or electrical power, which is outputted to the third connecting terminal and relates to the discharging of the electrical power storage device, when a current or electrical power output through the third connecting terminal is request.

9. The control apparatus as set forth in claim 1 ,
further comprising a third connecting terminal, which is provided separately from the first connecting terminal, and through which a current relating to discharging of the electrical power storage device flows via a second electrical connection,
wherein the controller is configured to control outputs by putting priority on a fourth current or electrical power among a third current or electrical power and the fourth current or electrical power, wherein the third current or ele
