EXEMPLARY PROJECT REALIZATIONS

Scope, tools & features:

The goal of the project was to provide hardware and software for a prototype design of a valve built upon the use of Shape Memory Alloy element monitoring system. The project requirement was that the valve is to be commanded by the controller over LIN bus.

  • Hardware and software prototype design for valve controller for SMA element.
  • Building valve controller circuit.
  • Requirements analysis and solution definition.
  • HW and SW prototype design.
  • Electronic schematics.
  • Software for the controller.
  • Bill of materials (prototype electronic components list).

Scope, tools & features:

The goal of the project was the development of 48V battery for Mild-Hybrid vehicles for one of the top European automobile manufacturers.

Following tasks were fulfilled: proactive liaising between the battery pack development and cell R&D. Creating and authoring the requirements specification for the battery energy storage (pack). Requirements Elicitation per ASPICE methodology to derive OEM requirements into cell level SOR. Ensuring consistency between requirements, implementation, and V&V methods throughout the project.

  • Responsibility for engineering activities (specification, design, Verification & Validation) related to the performance (energy, power and aging) of the energy storage (cells).
  • Ensuring consistency between the Battery pack specifications and the cell specifications.
  • Working closely with program managers to ensure the milestones are reached on time.

Scope, tools & features:

The project carried out in the United States, for a customer who is creating a new brand of premium electric cars. The project scope includes software development and creating its architecture in accordance with AUTOSAR standard.

Designated tasks include implementation of the device drivers, low-level software modules as well as Complex Device Drivers (CDDs) with creation and configuration of the interface between CDDs and AUTOSAR application layers.

Beyond that the project requires configuring the AUTOSAR stack and defining the software architecture.

  • Software development
  • Architecture definition
  • Configuration of the AUTOSAR stack
  • Implementation of device drivers, low level software modules and Complex Device Drivers (CDDs)
  • Debugging
  • Board bring-up
