ELECTRIC VEHICLE POWER STORAGE SYSTEM
First Claim
1. An electric vehicle power storage system provided with a plurality of power storage element rows composed of a plurality of power storage elements connected in series and mounted on an electric vehicle comprising:
- a parallel connecting switch configured to select the power storage element row and connect the same in parallel, and perform connection and disconnection with respect to an electric load mounted on the electric vehicle from one power storage element row to another;
a parallel connection switch controller configured to control the parallel connection switch;
a vehicle power requirement calculating unit configured to calculate a vehicle power requirement;
a remaining level detecting unit configured to detect a remaining level of the power storage element row;
a voltage detecting unit configured to detect a voltage of the power storage element row; and
a power storage system control apparatus configured to control the parallel connection switch on the basis of the vehicle power requirement, the remaining level of the power storage element row, and the voltage of the power storage element row.

Abstract
An electric vehicle power storage system includes a plurality of power storage element rows comprising a plurality of power storage elements connected in series, and includes a parallel connecting switch which selects the power storage element rows and connect the same in parallel, and performs connection and disconnection with respect to an electric load from one power storage element row to another. A parallel connection switch controller controls the parallel connection switch. A vehicle power requirement calculating unit calculates a vehicle power requirement, and a remaining level detecting unit detects a remaining level of the power storage element row. A voltage detecting unit detects a voltage of the power storage element row. A power storage system control apparatus controls the parallel connection switch on the basis of the vehicle power requirement, the remaining level of the power storage element row, and the voltage of the power storage element row.
