Abstract

There is disclosed a dynamic boost charging system having a monitoring component configured to measure total DC current and/or battery current and a reporting component configured to transmit output data of the total DC current and/or battery current measured. A battery charger control system in operable connection with the monitoring component receives the data of the total DC current and/or battery current measured by the monitoring component, and is configured to: obtain an initial time and/or charge measurement; determine a time and/or charge to complete a recharge cycle based on the time and/or charge measurement; selectively use at least two preset DC output voltage settings, one of the at least two preset DC voltage settings being a float voltage, and another of the at least two preset DC voltage settings being a boost voltage; and maintain the boost voltage until the time has passed the charge has been provided.

Claims (22)

1. A dynamic boost charging system, comprising:

a monitoring component configured to measure total DC current and/or battery current;

a reporting component configured to transmit output data of the total DC current and/or battery current measured by the monitoring component;

a battery charger control system in operable connection with the monitoring component to receive the data of the total DC current and/or battery current measured by the monitoring component, and configured to:

obtain an initial time and/or charge measurement;

determine a time and/or charge to complete a recharge cycle based on the time and/or charge measurement;

selectively use at least two preset DC output voltage settings, one of the at least two preset DC voltage settings being a float voltage, and another of the at least two preset DC voltage settings being a boost voltage; and

maintain the boost voltage until the time to complete a recharge cycle has passed and/or the charge to complete a recharge cycle has been provided;

wherein the battery charger control system is configured to monitor a magnitude and a timing of output current of at least two selectively used preset DC voltage settings.

2. A dynamic boost charging system, comprising:

a monitoring component configured to measure total DC current and/or battery current;

a reporting component configured to transmit output data of the total DC current and/or battery current measured by the monitoring component;

a battery charger control system in operable connection with the monitoring component to receive the data of the total DC current and/or battery current measured by the monitoring component, and configured to:

obtain an initial time and/or charge measurement;

determine a time and/or charge to complete a recharge cycle based on the time and/or charge measurement;

selectively use at least two preset DC output voltage settings, one of the at least two preset DC voltage settings being a float voltage, and another of the at least two preset DC voltage settings being a boost voltage; and

maintain the boost voltage until the time to complete a recharge cycle has passed and/or the charge to complete a recharge cycle has been provided;

wherein the battery charger control system is configured to compute the transition between boost voltage and float voltage settings using time and/or returned charge.

3. The dynamic boost charging system of claim 1 , wherein the monitoring component is a DC current sensor, integrated with monitoring circuitry of the battery charger control system.

4. The dynamic boost charging system of claim 1 , wherein the battery charger control system is configured to determine a charge time to complete a recharge cycle to recharge the battery at a faster rate and with greater capacity returned than a predetermined time period.

5. The dynamic boost charging system of claim 2 , wherein the monitoring component is a DC current sensor, integrated with monitoring circuitry of the battery charger control system.

6. The dynamic boost charging system of claim 2 , wherein the battery charger control system is configured to determine a charge to complete a recharge cycle to recharge the battery at a faster rate and with greater capacity returned than a predetermined time period.
