Benefits of technology

The invention is a hybrid battery system for electric vertical take-off and landing (VTOL) aircraft. The system uses two different types of batteries to power the aircraft in combination or separately. The high energy density battery provides the power needed for sustained flight and the low energy density battery provides the power needed for vertical take-off and landing. The system also includes a switch to switch between the two batteries during flight to maintain optimal performance. The use of a high energy density battery in a hybrid battery system allows for efficient use of power and suppression of damage to the battery during vertical landing. The invention also includes various techniques for managing the power output of the batteries during different stages of flight.

Problems solved by technology

A high energy density battery may not be capable of supplying the power needed for vertical take-off or landing without sustaining damage to the battery.
Towards the end of flight, a typical high energy density battery may output too low of a voltage for a vertical landing.

Abstract

An electrically-powered vehicle comprising a hybrid battery system is disclosed. The vehicle comprises a motor and a hybrid battery system coupled to the motor. The hybrid battery system comprises a first battery of a first energy density and a first power density and a second battery in parallel with the first battery. The second battery has a second energy density lower than the first energy density and a second power density greater than the first power density. The vehicle is configured to draw power disproportionally from the first battery in a first mode and disproportionally from the second battery in a second mode.

Description

BACKGROUND OF THE INVENTION[0001]In vertical take-off and landing (VTOL) aircraft, large amounts of power are applied at the start and end of flight to enable the aircraft to take off and land in a short distance. In an electric VTOL aircraft, a battery or battery system must sustain the aircraft for the entirety of flight as well as supply surges of power during take-off and landing. A high energy density battery may be used to provide a cost-effective and weight-effective solution to powering an aircraft. A high energy density battery may not be capable of supplying the power needed for vertical take-off or landing without sustaining damage to the battery. Towards the end of flight, a typical high energy density battery may output too low of a voltage for a vertical landing.BRIEF DESCRIPTION OF THE DRAWINGS[0002]Various embodiments of the invention are disclosed in the following detailed description and the accompanying drawings.[0003]FIG. 1 is a diagram illustrating an embodiment...
