Titanate industrial storage

The TiRack63 is a storage rack for large scale energy storage applications based on Leclanché powerful Lithium Titanate cells. The main benefit of this rack is that it can be used for 15000 charge/discharge cycles at 100% Depth of Discharge. The racks can be charged at a high rate of 3C (300A) and discharge at the same high rate providing a lot of power.

TiRacks are used to build large storage systems in containers or in buildings.

Each TiRack includes:

  • 15 lithium Titanate modules
  • One Rack controller to monitor and manage the rack
  • Switch unit to connect/disconnect the rack in the large system

This product has been developed to address a number of applications where a lot of power is required like:

  • Grid stabilization in on-grid applications
  • Providing short term power to cover the first seconds in a grid failure incident to industrial users.
  • Managing the integration of renewable energy (solar and wind) into off grid applications with diesel generators (e.g. mining),

Main Features

  • 63 kWh storage capacity
  • Long cycle life of 15000 cycles at 100% Depth of Discharge
  • Rapid charging and discharging at 3C
  • Modular setup – start small and grow when needed
