Electric storage apparatus
First Claim
1. An electric storage apparatus comprising:
- a plurality of lithium-ion batteries connected electrically in series, the plurality of lithium-ion batteries being divided into a plurality of blocks, the plurality of blocks including;
a first block having at least one lithium ion-battery which is replaced by a reusable lithium-ion battery, wherein the reusable lithium-ion battery is an old and used lithium-ion battery, anda second block having at least one lithium-ion battery which is configured to be used continuously without being a subject of replacement,wherein the first block has a resistance increase rate lower than a resistance increase rate of the second block, in a state immediately after the reusable lithium-ion battery is incorporated in the first block, and the resistance increase rate of each of the first block and the second block is larger than 1.

Abstract
A diagnosis apparatus performing a diagnosis for reuse of an electric storage apparatus including a plurality of electric storage elements connected electrically in series includes a voltage sensor detecting a voltage of each of a plurality of blocks, the plurality of electric storage elements being divided into the blocks; a current sensor detecting a current in the electric storage apparatus; and a controller calculating an internal resistance of each of the blocks based on outputs from the voltage sensor and the current sensor. The controller specifies the highest of the internal resistances of the plurality of blocks as a criterion to perform the diagnosis for the reuse of the electric storage apparatus.
