Document Type and Number:
Japanese Patent JP6751947
Kind Code:
B2
Abstract:
To provide a battery charge/discharge tester with which, when a prescribed condition is satisfied that short cycle measurement results with respect to a battery state is recorded, it is possible to record the measurement results of battery state data on a prescribed short cycle while preventing an increase in storage capacity.SOLUTION: The battery charge/discharge tester comprises: a measurement unit; a control unit; a first record unit for recording characteristic values for each first cycle in a first memory; a second record unit for recording characteristic values for each second cycle shorter than the first cycle in a second memory; and a recognition unit for recognizing that a prescribed first condition is satisfied. The second record unit shortens the second cycle after the recognition unit recognizes that the first condition is satisfied and records characteristic values for each of the reduced second cycles in the second memory, as well as records at least the characteristic values for a first prescribed period before the recognition unit recognizes that the first condition is satisfied and the characteristic values for a second prescribed period after the recognition unit recognizes that the first condition is satisfied.SELECTED DRAWING: Figure 1
