Geyser TEHO

High-power battery for a life-long heavy-duty use

or

High-power battery for heavy users

"Teho" is a Finnish word for power. TEHO product line represents the core of Geyser Batteries technology – providing solutions for industrial machinery and automotive industries, and serving the most demanding needs of customers in other heavy-duty segments.
The products of this line are all capable of extremely fast and frequent charging and discharging. The ECR modules are based on standardized cell blocks and the block amount and their interconnection can be customized.
Geyser TEHO is a safe and sustainable alternative to Li-ion batteries for many industrial applications.

Product examples

​

Blocks of cells

​

48V/???? 

Geyser Batteries ECRs are made using bipolar design, where cells are stacked together in blocks from which modules are built. This means improved power performance. It also provides additional boost in power and energy density, and eases the cooling requirements.

Geyser TEHO modules are built with 48V blocks. Using standardized blocks gives flexibility in design, and allows for customization to serve even the most complex and demanding customer needs. The blocks are characterized with flat discharge curves and high energy density: 

Performance

  • Standardized 12V, 48V blocks of cells. 

  • Custom designs (voltage, power performance) possible

  • 1.000,000+ cycles

  • Up to 20 Wh/kg (stored energy)

  • Up to XX kW/kg (ESR? Matched impedance, and so on)

  • Up to XXX W/kg continuous cycling

  • Low ESR

  • Flat discharge curve (no extra DC-DC conversion required)

  • Up to 15 Wh/kg delivered @25% DOD

  • Used at -40 to +60 °C

Benefits

  • Safe: non-toxic, non-flammable

  • Structural integration

  • Sustainable

  • 15+ years lifespan
