Lithium For Everything?Finding the Best Chemistry for the Application

Glenn Austin Green

Assistant Business Development Manager

EVB Technology (HK) Ltd

Agenda

• EVB Technology (HK) Ltd Background

• Presentation Purpose

• Li-ion Advantages (Real World Case)

• Case Studies for not selecting Li-ion

• Other EV applications?

• Take Away Point

EVB Technology Background• 100% owned by GP Batteries Group

• Factory located in Hong Kong

• Manufactures in Nickel Metal Hydride (NiMH)

and Lithium Ferro Phosphate (LiFePO4)

• 17+ years experience manufacturing large

format batteries

• One of the first Ovonic licensees for NiMH

• Second largest producer worldwide in NiMH

• Owner of Vectrix (e Maxi Scooter)

• Quality Accreditation – ISO/TS16949 Certificate

from DNV

Presentation Purpose

• To showcase via real world cases why we

must look at the total application (e.g.

working environment, nature of the task,

etc.) to judge the best chemistry for the

solution.

Advantages of Using Li-ion

NiMH

•3 Layers

•80kgs

•6.8 sec Acceleration (0 – 80km)

•~80km Range

LiFePO4

•1 Layer

•45kgs

•5.8 sec Acceleration (0 – 80km)

•~100km Range

Dangers of Lithium

Commercial Advantage vs. Li-ion

•Switched customer from

Pb Acid to NiMH

•Able to partner for 10

years/100,000km warranty

to end customers.

•No expensive BMS

system to drive cost up

further

Operating Environment Issue

•Li-ion operates best in mild

climates

•Extremes at both end of the

temperature range affects the

performance.

December 2010:

Oslo had a series of -28°C days –

only 3 failures.

2 software errors and

1 wiring error.

ZERO BATTERY FAILURES!!

Better Performance Demands

•Already using NiMH and

only wanted better

performance.

•Application had a high

max current draw (500 –

600A)

•Customer preference

limited the potential of a

Li-ion option.

Any EV Application?

Non-road mobile machinery contribute 7% (6.800

tonnes) and 11% (600 tonnes) of local emissions

of Nitrogen Oxides (NOx) and respirable

suspended particulates (RSP) although only

13,500 vehicles – Hong Kong Environment

Protection Department (May 2010).

Take Away Point

We must effectively communicate with our

customers on their application to strike the right

balance between expectations, budget limitations,

and technology.
