Method and apparatus for monitoring the maximum available capacity of a battery |
摘要 |
A method of monitoring a maximum available capacity of a battery includes providing a number of diverse end-of-discharge-voltage values. A counter is assigned to each of the end-of-discharge-voltage values. The battery is discharged. One of the end-of-discharge-voltage values at which the battery is discharged is determined. A counter reading of the counter assigned to the determined end-of-discharge-voltage value is incremented. The previous steps are repeated. The counter readings are read-off so as to obtain a number of read-off counter readings. Based on the read-off counter readings, a first factor representing a first measure of a decline in the maximum available battery capacity is determined. |

1. A method of monitoring a maximum available capacity of a battery comprising:
a) providing a plurality of diverse end-of-discharge-voltage values; b) assigning a counter to each of the plurality of diverse end-of-discharge-voltage values; c) discharging the battery; d) determining one of the plurality of end-of-discharge-voltage values at which the battery is discharged; e) incrementing a counter reading of the counter assigned to the determined end-of-discharge-voltage value; f) repeating steps c-e; g) reading-off the counter readings so as to obtain a plurality of read-off counter readings; and h) determining, based on the plurality of read-off counter readings, a first factor representing a first measure of a decline in the maximum available battery capacity. |
