Power source apparatus, vehicle and power storage system using the power source apparatus
First Claim
1. A power source apparatus comprising:
- a plurality of modules;
a main controller connected to the plurality of modules to control said modules; and
a current detection section to detect output line current flow,wherein each module comprises;
a battery block having a plurality of battery cells stacked together and connected in series and/or parallel;
a battery state detection section that detects the state of the battery cells; and
communication interface units for data communication with other modules and the main controller,wherein the main controller is connected to the communication interface units of the modules via communication lines,wherein the plurality of modules are connected in series and/or parallel with the output line,wherein the current detection section is connected to the main controller via a signal line, andwherein the main controller can perform computations based on data sent from the modules via the communication lines and/or information related to output current sent from the current detection section via the signal line.

Abstract
The power source apparatus is provided with a plurality of modules (10), and a main controller (2) connected with communication interface units (16) in each module via a communication line CB. Each module is provided with a battery block (12) having a plurality of battery cells (11) stacked together and connected in series and/or parallel, a battery state detection section (14) to detect the state of the battery cells, communication interface units for data communication with other modules and the main controller, and a memory section (18) that can store data received through the communication interface units. The plurality of modules are connected in series and/or parallel with an output line OL.
