Patent number: 10358043Abstract: An automatic rechargeable battery control module for a vehicle, such as a golf cart incorporates an automatic battery control system that automatically switches from charge to discharge modes with a single relay, thereby preventing the need to manually reset a relay switch due to an over or under voltage situation. An automatic battery control circuit is coupled with a battery management system and a relay contactor is opened and closed by a signal from the battery management system. The battery management system monitors a state of charge of the battery unit as well as current flow to and from a battery unit. The automatic rechargeable battery control module may have a state of charge output that is connected with a state of charge indicator to inform a driver of an approximate driving range or time remaining.Type: GrantFiled: September 12, 2017Date of Patent: July 23, 2019Assignee: Elite Power Solutions, LLCInventors: Yuan Dao, William Jeffrey Schlanger, Jennifer Dao

Patent number: 10116149Abstract: An automatic battery control system automatically switches from charge to discharge modes with a single relay, thereby preventing the need to manually reset a relay switch due to an over or under voltage situation. An automatic battery control circuit is coupled with a battery management system and a relay contactor is opened and closed by a signal from the battery management system. The battery management system monitors a state of charge of the battery unit as well as current flow to and from a battery unit. A parallel resistor is configured across the input and output sides of the single relay contactor and the voltage drop across the resistor indicates a connection to either a charging power source or a load. The connection is communicated to the battery management system by an optocoupler and if the battery unit has an acceptable state of charge, the relay contactor is closed.Type: GrantFiled: July 24, 2017Date of Patent: October 30, 2018Assignee: Elite Power Solutions, LLCInventors: Yuan Dao, William Jeffrey Schlanger

Patent number: 9929571Abstract: An integrated battery control system for energy storage incorporates a power control system to reliably provide power to a load and protects lithium ion batteries from over-charging and over-discharging. One or more power sources, such as renewable power sources, such as solar or wind power generators, or a generator, may be coupled with the integrated battery control system to provide power for charging the battery pack and/or for supplying power to said load. A portion of the power from a power source may be used to charge the battery pack and a portion may be provided to a load. A control circuit and one or more microprocessors may control the components of the system to provide power in an efficient manner. Power to and from the battery may run through an inverter and a control system may open and close switches to control flow of power in the system.Type: GrantFiled: March 29, 2016Date of Patent: March 27, 2018Assignee: Elite Power Solutions LLCInventors: Yuan Dao, William Jeffrey Schlanger

Patent number: 9595847Abstract: An uninterrupted power supply system incorporates a plurality of lithium batteries as a back-up power supply to an AC power supply. In the event that there is an interruption in the AC power supply, a power output switch is automatically activated by a power control system to draw power from a lithium battery pack. In an embodiment, a battery pack is monitored by a battery management system that is coupled to battery monitoring modules couple to each battery. The battery management system may be configured to monitor the voltage and/or temperature of each battery. In another embodiment, an uninterrupted power supply system comprises a battery unit balancing system that maintains each battery within a battery unit below a threshold voltage value. A charging circuit and discharging circuit are used to maintain the batteries in a ready state of charge when not being used for the output power.Type: GrantFiled: March 25, 2014Date of Patent: March 14, 2017Assignee: Elite Power Solutions LLCInventors: Yuan Dao, William Jeffrey Schlanger

Patent number: 9553460Abstract: A wireless battery management system includes a computing device and first and second battery unit monitoring modules. The computing device includes an output data request port and an input data port. In response to a data request from the output data request port of the computing device, a first battery unit monitoring module transmits data of the first battery unit to the input data port of the computing device wirelessly and may transmits a data request to the second battery unit monitoring module. In response, the second battery unit monitoring module may transmit data of the second battery unit to the input data port of the computing device wirelessly or transmit data of the second battery to the first module for wireless transmission. In addition, each battery unit monitoring module may communicate wirelessly and independently with the computing device.Type: GrantFiled: March 13, 2015Date of Patent: January 24, 2017Assignee: Elite Power Solutions LLCInventors: Yuan Dao, William Jeffrey Schlanger

Patent number: 9371067Abstract: An integrated battery control system incorporates a battery management system and a power control system to reliably and safely provide power to vehicles and other mobile devices. The integrated power control system incorporates safety features to protect the batteries from dropping below a threshold voltage or being overcharged, and from operating the vehicle when it is coupled with an AC power supply. An integrated power control system may be contained in a control enclosure having a computing device, battery power input, an AC power input, a power output switch, a power output, a key-switch interface and a shunt to measure current flow. The power control system regulates electrical power delivery to a drive motor and a pre-charge resistor as a function of the battery state of charge. When a battery unit is below a threshold value, power delivery is disabled to the drive motor and a pre-charge resistor.Type: GrantFiled: March 20, 2015Date of Patent: June 21, 2016Assignee: Elite Power Solutions LLCInventors: Yuan Dao, William Jeffrey Schlanger
