Abstract
The disclosed system includes two battery packs, at least one motor, a generator subsystem, controllers, and a switch wherein the battery packs are independent of one another but can either be undergoing charging or propelling an EV separately. A controller monitors comparative charge levels of the two battery packs and at a predetermined charge-difference value triggers the switch to reverse the roles of the battery packs.
Claims20
A system comprising:
- a first battery pack;
- a second battery pack;
- a first motor in operative communication with a vehicle propulsion system, the first battery pack, and the second battery pack;
- a generator subsystem;
- and
- a controller configured to initiate use of at least one of the first battery pack or second battery pack to power the first motor.
3 more elements
A method comprising:
- monitoring, via at least one controller, a first state of charge in a first battery pack in an electric vehicle;
- monitoring, via the at least one controller, a second state of charge in a second battery pack in the electric vehicle;
- determining, via the at least one controller, if the first state of charge or the second state of charge falls below a threshold value;
- instructing, via the at least one controller, use of at least one of the first battery pack or the second battery pack to power a motor in operable communication with a vehicle propulsion system;
- and
- instructing, via the at least one controller, a generator subsystem to charge at least one of the first battery pack or the second battery pack not powering the motor in operable communication with a vehicle propulsion system.
3 more elements
A system comprising:
- a first battery pack;
- a second battery pack;
- a first motor operative to propel a vehicle;
- a generator subsystem operative to charge at least one of the first battery pack or second battery pack;
- at least one controller operative to measure battery pack charge levels;
- the at least one controller operative to compare measured charge levels to a predetermined charge-level-difference value;
- the at least one controller operative to trigger a switch subsystem wherein the first battery pack is used to propel a vehicle and the second battery pack is being charged;
- and
- the at least one controller operative to trigger the switch subsystem wherein the first battery pack is being charged and the second battery pack is used to propel a vehicle;
- wherein the switch subsystem is configured to, under controller command, reverse roles of the first battery pack and the second battery.
