“A lot has been written about energy storage but a lot hasn’t been demonstrated, so we’re very excited. It’s one thing to write it in a text book, but it’s another thing to actually get into a live environment and provide benefits for a modern smart grid application.”
-Carmine Pizzurro, founder of eCAMION
eCAMION has developed a novel energy storage system based on Lithium-ion batteries, termed Community Energy Storage (CES). The first version of the system has been developed with funding support from Sustainable Development Technology Canada (SDTC) and is a collaborative effort alongside the University of Toronto, Dow Kokam and Toronto Hydro.
The first 500kW/250kWh unit was installed adjacent to Roding Arena and Community Centre, 600 Roding Street, North York, ON, Canada. The CES unit is tied to the Community Centre’s 75kW solar panels and is grid-connected to Toronto Hydro. Two more CES units are scheduled for installation in 2013/2014 to complete the SDTC project.
The CES system has better performance and lower costs for high power/energy applications; it is 98%+ efficient and can operate in -20°C and up to 60°C. The footprint is sized to fit standard utility padmount switchgear. It is more unobtrusive and integrates seamlessly for utilities to install, operate and maintain.
- Innovative designs including patent pending module design and cooling
- Flexible and scalable module design from 75kWh to 250kWh
- Grid support for up to 150 homes
- Smart Battery Management System (BMS)
- Intelligent controls with utility grid integration and coordination that automate the CES’ operations based on local utility grid conditions
- Master controller monitors the system and has appropriate safety redundancies
- Each battery module is analyzed, monitored and optimized for State of Charge (SOC), Voltage, Current, Cell Capacity, Temperature & Efficiency
- Cell balancing
- Safety protocols with safety alarms and shutdowns
- Protections against under/over-voltage, temperature and over currents
- Nano second switches between charge/discharge
- Web based and Ethernet ready
- Designed and configured to work smoothly with Control, Protection Power Management system
- Stand-alone unit within CES control box that that has built in intelligence to manage Energy Storage system, Inverter system and grid-controls
- Unified hardware-software architecture that encompasses strategies and the corresponding algorithms associated with control, protection, power-energy management for Community Energy Storage (CES) unit.
- The CPPM selects and activates a new CES mode of operation by means of its software
intelligence and logics, based on real time commands from utility control room, from a
customers remote signal or on site commands
- In conjunction with Utility requirements selects and invokes a CES mode of operation based on the battery State Of Charge (SOC) and distribution grid immediate and longer-term (few hours) needs
- The Design structure is easily customizable to can accommodate additional functions in
terms of operation of the Inverter and interface with the utility
- Can provide fast, medium and slow control/EMS functions without changing its algorithms
- Can be customized with off-the-shelf hardware platform depending on the customers
- Has operational clearly defined modes at different speed (slow to fast) depending on the
grid and the type of Inverter
