ENAX
the leading engineering company
to materialize rapid prototyping of advanced lithium ion batteries

Power Supply = Battery System Performance

The customer’s needs is nothing more than to have expected performance as the power supply on their system.
To meet this demand and respond to customer’s requirements, we determine the battery performance, fix the pack control technology and finalize with manufacturing prototype units to verify the specification with sense of speed.
Rapid MODELING is the function ENAX is expected to provide the market.

Two Rapid Service Models

ENAX’s Rapid MODELING is based on following two service models.

  • (1)Rapid ONE
    Propose the selection of battery specifications and pack control technology customized for each requirement.
  • (2)Rapid TWO
    Manufacture and analyze data from prototype units (ES units*) for testing and verification to determine final specifications of CS units**.

Plus ONE

The final stage of performance verification is made with CS units to be installed on to customer’s existing system.
Producing sizable quantity of CS units required for their purpose with sense of speed is crucial.
ENAX has flexibility to manufacture the products in requested quantities; from small-scale production (several hundred cells and several dozen units) to mass-production level in larger quantities.

* ES units: Engineering Sample units
** CS units: Customer Sample units

MESSAGE

To build “the future created by lithium ion batteries (LIB)” with absolute certainty, ENAX never cease to pursue nor challenge

Masaki Saikusa
President and CEO

As the momentum gathers to transform electrification of vehicles into reality, just as with cloud services through the integration with AI, the values sought for batteries for automotive applications (LIB) has been changing drastically from ownership (tangible factors) to utilization (intangible factors).

This is all the more reason ENAX believes the value proposition we offer is our agile solutions. We are capable and feasible. To propose specifications speedily for LIB and its system to materialize the power source needs of customer’s “intangible factors”. To convert these specifications into actual products as “tangible factors”.

Proposing One Stop Solutions to resolve challenges for “intangible factors” and providing Rapid Prototyping Solutions to bring them into shape. These are two keywords to describe ENAX’s activities.

With our promising and reliable technology reinforced by rich experience in research and development over the past years, ENAX has implemented various joint development projects in partnership with worldwide leading companies in the automotive and machinery industries.

Today, as we expand our potential with introducing the new business model leading from system proposals to solution proposals, we aim to make an extensive growth together with our innovative customers.

Remaining to be your best Technology Partner and Solutions Partner, up until now and from now on, ENAX looks forward to your continuous support as we undertake the challenges and outface the new stages of battery industry with innovative technology and solutions.
