Battery Management System (BMS) Development

Battery Management System (BMS) Development

Role Overview

You will be responsible for the development of the battery management system (BMS) for the flying car.

  • Study the BMS specifications and create the required specifications based on the aircraft system requirements and battery specifications.
  • Request design and manufacturing to partners, and conduct coupling tests and analysis with the airframe system and battery.
    (e.g., analysis and evaluation of battery measurements/SOC status estimates, evaluation of communication with aircraft systems, etc.)
  • Safety analysis (FTA, FMEA, etc.) to obtain type certification, and compilation of evidence for design review/evaluation results, etc.
  • Relationship building with partners
  • Implementation of partner selection, control, quality audit, etc.

There is nothing better than the joy of creating a “flying car” with your own hands. Various teams, such as power electronics, flight control, aerodynamics, and certification, work in unison and concentrate on the single goal of creating a flying car.
In addition, since we are involved in the entire process from specification development to actual testing, from upstream to downstream, it is an environment where we can strongly feel that we have created the product with our own hands.
We are proud to be an environment where you can enjoy “One & Only” development that you can only experience at SkyDrive.

The lithium-ion battery used in the flying car must have a large capacity and light weight in order to “fly safely”, and above all, it must be safe and reliable.
In addition, as a small and elite development team, you will be involved in upstream processes such as the formulation of requirement specifications, and you will be involved in a wide range of technical elements that make up the battery, such as cells, packs, and controls. This is an environment where you can fully feel the satisfaction of having created the battery control system for a flying car with your own hands.


Experience in ECU/microcomputer board software or hardware development (at least 5 years in either case


One of the following

  • Experience in the development of eVTOL, automotive and/or aircraft ECUs
  • Experience in functional safety development
  • Experience in the development of battery SOC/SOH state estimation control logic.
  • Experience in modeling development in MATLAB.

What we are looking for

  • The ability to work towards achieving objectives while flexibly incorporating the opinions and ideas of others.
  • The person who can think independently and proceed with things while checking with the supervisor.


  • Development Base Toyota(Asuke-Chiku, Toyota City, Aichi)or Tokyo

*If you live outside Aichi Prefecture, you must be able to travel to the development site.

Benefits and Others
