HELIOS - High Energy Lithium-ion Storage Solutions
Overview
Background & policy context:
The reluctance of OEM worldwide to extend electric drive applications to the private customers depends partly on considerations with respect to customer acceptance: limited range in the case of electric vehicles, long charging time after battery depletion, costs). But also on the increased reliability and life span that private customers are entitled to expect. The mission of the large scale integrating project HELIOS is to make CMOS photonics accessible to a broad circle of users.
Objectives:
The first goal of HELIOS project was to evaluate electrochemical couples (of lithium–ion cells) whose lower voltage window matches perfectly with the stability window of the electrolyte, which should guarantee an outstanding steadiness of the performance during ageing, and an intrinsic excellent safety.
The items that were evaluated are: performance, safety, life, recyclability and global cost. Another issue addressed by the project was the definition of a European standard for safety and life (cycle/storage) tests, adapted to high energy applications such as electric vehicles, plug-in hybrid electric vehicles and Heavy Duty Hybrid Trucks.
Methodology:
The project partners included six OEMs, one battery manufacturer, test Institutes/Universities and one recycler.
HELIOS drove the European RTD in CMOS photonics and paved the way for industrial development. The project included the development of essential building blocks such as: efficient sources (silicon-based and heterogeneous integration of III-V on silicon), fast modulators and, beyond, the combination and packaging of these building blocks for the demonstration of complex functions, addressing a variety of industrial needs:
- a 40Gb/s modulator on an electronic IC;
- a 16x10 Gb/s transceiver for WDM-PON applications;
- a photonic QAM-10Gb/s wireless transmission system;
- a mixed analog and digital transceiver module for multifunction antennas.
The results of HELIOS will pave the way for applications of CMOS photonics for other fields, e.g. sensors or optical processing. HELIOS will make integration technologies accessible for a broad circle of users.
