## Abstract

Apparatuses, systems, and methods are presented for battery charging. A charging connector may connect to power terminals of a battery. A data connector may connect to a battery. A charger controller may read battery data from a battery via a data connector, set a completion threshold based on the battery data, and charge the battery via a charging connector until the completion threshold is satisfied.

## Claims

### Claim 1

An apparatus comprising:
a charging connector configured to connect to power terminals of a battery;
a data connector configured to connect to the battery; and
a charger controller configured to:
read battery data from the battery via the data connector,
set a completion threshold based on the battery data, and
charge the battery via the charging connector until the completion threshold is satisfied, and
stop charging the battery in response to the completion threshold being satisfied,
wherein the data connector comprises one or more electrical conductors distinct from electrical conductors of the charging connector, and
wherein reading the battery data comprises reading one or more of:
a charge cycle count for the battery, a battery identifier, a battery temperature, a temperature per cell, a battery current, a current per cell, a battery voltage, a voltage per cell, a battery state-of-charge percentage, and one or more safety alert flags, and
wherein setting the completion threshold based on the battery data comprises adjusting the completion threshold to less-than-full capacity,
wherein charging the battery comprises:
supplying power to the battery above a peak battery voltage, and in response to the battery charge reaching a predetermined charge threshold, reducing the power supplied to the battery,
wherein the battery data comprises an open-circuit voltage for the battery and a state-of-charge percentage for the battery,
and wherein the charger controller is further configured to perform a deep cycle discharge of the battery, prior to charging the battery, based on determining that the state-of-charge percentage is inconsistent with the open-circuit voltage.

### Claim 2

An apparatus comprising:
a charging connector configured to connect to power terminals of a battery;
a data connector configured to connect to the battery; and
a charger controller configured to:
read battery data from the battery via the data connector,
set a completion threshold based on the battery data, and
charge the battery via the charging connector until the completion threshold is satisfied, and
stop charging the battery in response to the completion threshold being satisfied,
wherein the data connector comprises one or more electrical conductors distinct from electrical conductors of the charging connector, and
wherein reading the battery data comprises reading one or more of:
a charge cycle count for the battery, a battery identifier, a battery temperature, a temperature per cell, a battery current, a current per cell, a battery voltage, a voltage per cell, a battery state-of-charge percentage, and one or more safety alert flags, and
wherein setting the completion threshold based on the battery data comprises adjusting the completion threshold to less-than-full capacity,
wherein charging the battery comprises:
supplying power to the battery above a peak battery voltage; and in response to the battery charge reaching a predetermined charge threshold, reducing the power supplied to the battery,
wherein the battery data comprises an open-circuit voltage for the battery and a state-of-charge percentage for the battery, and
wherein the charger controller is further configured to perform a deep cycle discharge of the battery, prior to charging the battery, based on determining that the state-of-charge percentage is inconsistent with the open-circuit voltage, and
further comprising:
a second charging connector configured to connect to power terminals of a second battery; and
a second data connector configured to connect to the second battery, wherein the charger controller is configured to read second battery data from the second battery via the second data connector, and to direct power between the charging connector and the second charging connector based on the battery data and the second battery data.

### Claim 3

A system comprising
a battery configured to provide power to an electrical device;
a charging apparatus separate from the electrical device, the charging apparatus comprising:
a charging connector configured to connect to power terminals of the battery;
a data connector configured to connect to the battery; and
a charger controller configured to read battery data from the battery via the data connector, to set a completion threshold based on the battery data, and to charge the battery via the charging connector until the completion threshold is satisfied,
and to stop charging the battery in response to the completion threshold being satisfied, and
wherein setting the completion threshold based on the battery data comprises adjusting the completion threshold to less-than-full capacity, and
wherein the charging apparatus further comprises:
a second charging connector configured to connect to power terminals of a second battery; and
a second data connector configured to connect to the second battery,
wherein the charger controller is configured to read second battery data from the second battery via the second data connector, and to direct power between the charging connector and the second charging connector based on the battery data and the second battery data.
