EVEREST energy storage

EVEREST – Overview

The EVEREST system is a modular energy storage device, using second life battery packs from electric and hybrid vehicles, to act as aggregated grid support.
Incorporating bi-directional inverter rectifiers, banks of batteries will be linked together and managed by a single control unit that will allow the charging of the batteries with there is excess supply or utilise battery capacity to support peak demand.
The system can also support functions such as renewable energy integration as well as capturing regenerative energy from a battery simulator and a rolling road.
The modular energy storage device can reinforce the Low Voltage (LV) grid at the point of use, as well as taking advantage of off peak and green energy generation and provide potential revenue for the operator through its energy storage capacity.

Project consortium

The EVEREST consortium is lead by EValu8 Transport Innovations Limited, with Future Transport Systems as the technical lead and providing project management.

  • EValu8 Transport Innovations Limited – lead partner
  • Future Transport Systems – programme management and technical lead
  • Lotus Engineering – communications controller and technical support
  • Circontrol – power management conditioning
  • The APT Group – electric vehicle charging systems
  • Goodwolfe Energy – cell and battery system technologies

Project Outcomes

The primary use of the EVEREST unit is as a fast charge hub for electric vehicles, it will provide multiple significant outcomes:

2nd Life Battery Packs – as electric vehicle uptake increases, so will the number of 2nd life battery packs, which are expensive to decommission. The EVEREST system will greatly extend the life of these battery packs, significantly reducing the cost of decommissioning. With the modular systems being developed, additional and upgraded battery packs can be added, and the EVEREST system is scalable, so as battery pack technology improves and capacity increases, the EVEREST installations will be able to scale with them.

Extending the life of the battery packs will have a positive impact on the residual value of EVs, and therefore the associated overall costs of electric vehicles.

Fast Charge Capability – EVEREST will allow the installation of DC fast charge capability to areas that would not otherwise be able to support the infrastructure, potentially expanding the fast charge network across the UK leading to an increased uptake of electric vehicles.

A major cost associated with the installation of fast chargers is the infrastructure work required to support them, and this cost will be greatly reduced through the implementation of the EVEREST system.

Data – EVEREST will supply vital data on the degradation and capacity of 2nd life battery packs. This information will be utilised to explore other avenues for the use of 2nd life batteries, and may also assist in the future design of battery packs.

Grid Reinforcement and Renewable Energy – The Everest system is a modular energy storage device, using second life battery packs from electric and hybrid vehicles, to act as aggregated grid support. Through the integrated back office communication system all EVEREST modules can be linked to an aggregation mechanism, mimicking a larger single mono block installation. The EVEREST solution also offers the opportunity to integrate local embedded power generation technologies such as wind, solar and bio-fuel.
