Project Status

Project Update

The project has received UL 1973 certification. Battery test beds have arrived to the UCSD site and are being tested in warehouse until LRIP facility is established, which is currently what the REMS group is tasked with. MOAB enclosure arriving to UCSD site Q2, 2023. Plan to begin field testing Q3, 2023. LRIP facility begins Q 3, 2023. TAC meeting being held in Q3, 2023. Holding 1st CPR report September 2023.

The Issue

As California approaches its goal of 5 million zero-emission vehicles on the road by 2030 (Brown, Executive Order B-48-18), there is an increasing need to find alternative applications for the vehicle batteries after they have reached the end-of-life in the vehicle application. However, the cost-effectiveness of reusing second-life EV batteries is hindered by lengthy and costly processes of logistics and repurposing, compromised system performance, and long-term safety and reliability concerns.

Project Innovation

Smartville developed and demonstrated a prototype battery energy storage system that addressed many of the challenges associated with repurposing EV batteries for stationary grid storage, including the mitigation of battery imbalances inherent to used lithium-ion batteries as well as the low-cost integration of batteries with multiple form factors and electrical and thermal characteristics.

Smartville’s solution centers on its battery energy storage system called MOAB (Modular Assembly Battery) unit that includes vertically-integrated designs and components for communication and power control interfaces, DC-switching and pre-charge controls, isolation and common mode current protections, and thermal and environmental controls. Under this grant, Smartville will seek to reduce fabrication and build costs compared to its prototype MOAB V1 design developed under EPC-19-038 and achieve the required standards certifications to offer MOAB as a competitive product in the California market under relevant jurisdictional permitting and financial sectors.

Project Goals

Finalize the design and pre-production engineering of Recipient’s MOAB Version 2.
Demonstrate operation of MOAB Version 2 (V2) at a utility customer site for a minimum of 12 months.
Improve repurposed EV battery operations through battery controls.
battery State-of-Health (SOH) and extend the overall lifecycle of retired EV batteries.
Address lithium-ion supply chain issues through the reuse of battery assets available within California.
Establish an initial LRIP facility and process for MOAB V2.
Dramatically decrease the cost of Recipient’s MOAB product per-unit build.
Lower per-unit production labor hours to increase unit production yields.
