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 (11)

1. A dynamic boost charging method, comprising:

measuring total DC current and/or battery current with a monitoring component;

transmitting output data of the DC current measured by the monitoring component to a battery charger control system;

determining an initial charge time by the battery charger control system;

determining, by the battery charger control system, a time to complete a recharge cycle and/or a charge to complete a recharge cycle, based on the output data of the DC current measurement;

selectively producing a charging current from at least two preset DC voltage settings with the battery charger control system, one of the at least two preset DC output voltages being a float voltage, and another of the at least two preset DC output voltages being a boost voltage; and

maintaining boost voltage for the determined time to complete a recharge cycle and/or until the determined charge to complete a recharge cycle has been provided.

2. The dynamic boost charging method of claim 1 , wherein selection of DC voltage settings is performed by the battery charger control system which includes a DC current sensor integrated with the monitoring circuitry of the battery charger control system.

3. The dynamic boost charging method of claim 1 , further comprising computing a given time to transition between boost voltage and float voltage with the battery charger control system, and recharging the battery at a faster rate and with greater returned charge with the given time than a non-computed time period.

4. The dynamic boost charging method of claim 1 , further comprising monitoring a magnitude and a timing of output current of the selectively used two preset DC output settings with the battery control system.

5. The dynamic boost charging method of claim 1 , further comprising computing the transition between boost voltage and float voltage settings with the battery charger control system using time and/or returned charge.
