OXIS Energy is the lead partner in the Revolutionary Electric Vehicle Battery (REVB) project, a collaboration with Imperial College London and
Cranfield University. The project is developing the Ultralight cell technology specifically for Electric Vehicles and began in November 2013,
running until late 2016. It is funded by the Innovate UK’s Integrated Delivery Programme (IDP9) and will result in a compound increase in the
performance and safety of next generation electric vehicles.
Notes:
1.
Peak power figures are based on a 30 second discharge pulse.
2.
Maximum continuous discharge is expressed as a C-Rate, defined as a ratio of the maximum continuous discharge power (W) to the typical cell capacity (Wh).
3.
Cycle life is based on 80% Depth of Discharge at a temperature of 30°C, before its capacity is reduced to 80% of its beginning of life capacity. Depth of Discharge is the percentage of the cell’s rated capacity discharges relative to a fully charged condition. From 2017 Q1, cycle life for is the total number of charge and discharge cycles that the cell can
sustain using the simulated New European Driving Cycle test before its capacity is reduced to 80% of its beginning of life capacity. Prior to this date, it is based on 0.2C discharge rate and 0.1C charge rate
