Abstract

Systems and methods are provided for displaying operating data for a re-chargeable battery for an electric vehicle. The system comprises a re-chargeable battery for powering components of an electrical vehicle, a sensor that detects a present level of charge in the battery and a display. The display receives the present level of charge of the battery from the monitor and displays the present level of charge in the battery, a required level of endurance for the battery that is based on a planned operational parameter for the vehicle, a minimum level of charge in the battery that meets the required level of endurance, and an amount of time needed to re-charge the battery to achieve the minimum level of charge.

Claims (15)

  1. A system for displaying operating data for a re-chargeable battery for an electric aerial vehicle, comprising: a re-chargeable battery for powering components of the electric aerial vehicle; a sensor for the battery that detects a present level of charge in the battery; and a display that receives the present level of charge of the battery from the sensor, and shows, the present level of charge in the battery, a required endurance level for the battery, where the required level of endurance is based on a planned operational parameter for the electric aerial vehicle, a minimum charge level in the battery that meets the required endurance level of the battery, and an amount of re-charge time for the battery to achieve the minimum charge level in the battery.
  2. The system of any preceding claim, where the planned operational parameter for the electric aerial vehicle is automatically determined from a flight plan for an aircraft by a flight management system (FMS).
  3. The system of any preceding claim, where the planned operational parameter for the electric aerial vehicle is manually entered by an operator of the electric vehicle.
  4. The system of any preceding claim, where the minimum charge level includes a buffer to allow for an increased required endurance level of the battery during operations.
  5. The system of any preceding claim, where the re-charge time for the battery is calculated based on the historical recharge data of the battery.
  6. The system of any preceding claim, where the re-charge time for the battery is calculated based on the age of the battery.
  7. The system of any preceding claim, where the re-charge time for the battery is calculated based on the temperature of the battery.
  8. The system of any preceding claim, where the required endurance level and the minimum charge level are continuously recalculated and dynamically updated during operation of the electric aerial vehicle based on a present discharge rate of the battery.
  9. The system of any preceding claim, where the display further shows a corresponding battery charge level that will remain upon arrival at one or more waypoints and a destination of the electric aerial vehicle.
  10. The system of any preceding claim, where the re-chargeable battery is part of a multi-battery pack comprising a plurality of individual re-chargeable batteries.
  11. The system of Claim 10, where the display shows the present level of charge, a required charge level, and an amount of re-charge time for each individual re-chargeable battery.
  12. The system of Claim 8, where the system provides a warning if the battery will reach a zero percent charge prior to reaching its destination, as determined by the present discharge rate.
  13. The system of any preceding claim, where the display further shows an alert message comprising at least one of: a number of hours until maintenance is required for the battery, a number of hours until a replacement is required for the battery, and a number of hours until a predicted failure of the battery.
  14. The system of any preceding claim, where the display indicates a warning that the battery is malfunctioning, improperly installed, or is an improper type of battery.
  15. The system of any preceding claim, wherein the electric aerial vehicle comprises an unmanned aerial vehicle, UAV.

Description

TECHNICAL FIELD The present invention generally relates to operations of electric vehicles, and more particularly relates to a system and method for a mission-based battery status display for electric vehicles. BACKGROUND As electric powered vehicles become more common, is critical for both operators and maintenance personnel of those vehicles to receive accurate information regarding the operational status of the batteries which power the vehicles. The operational status may include such information as: the current charge level of the batteries: the range of the vehicle at the current charge levels; the time required to charge the batteries; etc. Hence, there is a need for a system and method for a mission-based battery status display for electric vehicles. BRIEF SUMMARY This summary is provided to describe select concepts in a simplified form that are further described in the Detailed Description. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. A system is provided for displaying operating data for a re-chargeable battery for an electric vehicle. The system comprises: a re-chargeable battery for powering components of the electric vehicle; a sensor for the battery that detects a present level of charge in the battery; and a display that receives the present level of charge of the battery from the sensor, and shows, the present level of charge in the battery, a required endurance level for the battery, where the required level of endurance is based on a planned operational parameter for the vehicle, a minimum charge level in the battery that meets the required endurance level of the battery, and an amount of re-charge time for the battery to achieve the minimum charge level in the battery. A system is provided for displaying operating data for a re-chargeable multi-battery pack for an electric vehicle. The system comprises: a re-chargeable multi-battery pack for powering components of the electric vehicle, where the multi-battery pack comprises a plurality of individual re-chargeable batteries; a sensor that detects a present level of charge in each battery; and a display that receives the present level of charge of each battery from the sensor, and shows, the present level of charge in each battery, a required endurance level for the multi-battery pack, where the required level of endurance is based on a planned operational parameter for the vehicle, a minimum total charge level for the multi-battery pack that meets the required endurance level of the battery, and an amount of re-charge time for each battery to achieve the minimum total charge level for the multi-battery pack. A method is provided for displaying operating data for a re-chargeable battery for an electric vehicle. The method comprises: detecting a present level of charge in a re-chargeable battery with a sensor, where the battery powers components of the vehicle; receiving the present level of charge of the battery from the sensor with a display; and showing on the display, the present level of charge in the battery, a required endurance level for the battery, where the required level of endurance is based on a planned operational parameter for the vehicle, a minimum charge level in the battery that meets the required endurance level of the battery, and an amount of re-charge time for the battery to achieve the minimum charge level in the battery.
