Summary

Our vision – Renewable Energy

Optimized range of technologies and products for storage in renewable energy applications.

• Reliability, performance and efficiency.

• Diversified product offering

• Wide spectrum of technology offering to accommodate various applications

Lead based Chemistry

Nickel based Chemistry

Lithium based Chemistry

PowerSafe batteries are designed and optimised against specific applications for efficient

cycling in the evolving Renewable Energy space of Solar, Wind and Water power

generation.

Working closely with customers, we help them scope solutions to manage their stored

energy effectively and efficiently.

Solar Off-Grid market

Worldwide trend on solar-based power utilities.

Laws and regulations are focused on renewable more and

more. > Governments financial support provided !

There are currently two main

markets within the Solar Off-Grid

applications:

Large solar plants using proven

technologies like OPzV, NiCd, OPzS

- Small to medium

All kinds of technologies, RE

Requirements: > 700 cycles / DOD60%

Market overview (1/4)

Hybrid market

Save fuel on diesel generator to reduce costs and carbon

footprint. > 40,000 base stations in Africa !

Networks expanding at 120,000 base stations per year

The financial economics and the remote

Location logistic demand a battery life

Of at least 3 years.

3 years means > 1100 cycles at a DOD

of 50% or more.

Therefore 2 battery ranges are proposed:

OPzV, AGM pure lead

Market overview (2/4)

Smart Grid

..means an optimized management of energy generation,

distribution and consumption. >provide energy at any

time and at any places when needed! Therefore an energy

storage is absolutly essential.

- Voltage/frequency regulation

- Peak shaving

- Load leveling

Flat plate technology with large

capacities are required for this

application: VRLA AGM,

VRLA Gel, VRLA AGM Gel

• TPPL pure lead thin plate technology

- 12 volt: SBS B14/B14F, C11/C11F, 100/100F, 170F & 190F

- 2 volt: SBS 410

• Key benefits & claims: – 15 years design life (20°C)

– High cycle capability (up to 1200 cycles @ 60% DOD)

– Compact design & High energy density

– Operating temperature range: -40°C to +80°C

– 2 year shelf life @ 20°C

• Made in UK

• Main applications: Hybrid

PowerSafe SBS EON (1/3)

The advantages of high purity materials are:

• Low rate of grid corrosion

• Low float charge current

• Low gassing rate

= High temperature resistance

Longer Service Life

• Low rate of self discharge = Long Shelf Life

• Thinner positive grids = High Energy Density

High Performance

High purity materials (TPPL) are more expensive….

but the advantages outweigh the extra cost
