Seven myths about electric vehicles
By Jim Motavalli, Mother Nature Network
A few things about the e-jeepney project:
1. range is only 65 kilometers (with new, fully charged batteries). It is also important to note that as the batteries age (during regular use) the range of the ejeepney drops well below the claim 65 km range.
2. recharging takes at least 8 hours.
3. powered by lead acid batteries.
4. slow top speed.
5. recharging power still taken from the Meralco power grid (what happened to the garbage fueled recharging station?)
6. Each ejeepney costs P650,000. A quarter is battery cost alone. Does not include cost of the vital recharging system.
7. A standard jeepney costs around the same. A multicab is much cheaper.
8. lead acid batteries storage capacity decline with each recharge cycle. Deep cycle batteries have a maximum cycle life of around 500 cycles if done properly. Less than optimum recharge (wrong recharging rate) or discharge conditions (example: drained too much) drastically shortens battery life. So assuming one cycle per day and operated daily, the batteries will need to be replaced in 1 year and five months time.
9. E-jeepney owner/operator will need to have P170,000 in his savings to purchase a new battery pack to replace the worn out old battery-pack in his 1.5 year old e-jeepney.
10. makati route e-jeepneys have yet to prove they are economically self-sustaining for public transport operators since they are still financed by foreign NGOs in their day-to-day operations.
11. SM MOA, one of the first to adapt electric powered "trams" to ferry people around the commercial complex have ditched the electric powered trams and replaced them with petrol power trams instead. Ever wondered what made one of the most success business owner change his mind about electric transport around his flagship commercial complex?
12. In the end, when taken as a whole, it will cost more to operate than a regular jeepney.
13. e-jeepney published "press-kits" are deceptive when they state the operating cost of the e-jeepney because they do not include the cost of operating the re-charging "station" nor the cost of the expensive replacement battery-pack into the calculations.

hello po,
That was very informative, thanks! I already visited U.P. and they currently have 3 E-Jeeps being tested at the Nat. Transp. Bldg.
Well question ko lg po (sorry if na ulit), ano yung mga indicators that shows na viable yung application ng e-jeep sa isang city... is there already a national program for the adoption of e-jeeps for testing in their cities?
regarding the battery life... I think Motolite can think of ways to make this cheaper. charging stations.. studies are still lacking, coordination between cities on how to properly integrate other forms of transport systems in the current one.
I may change my project to the study of the e-jeeps application in Marikina city, since they already have a community with good living conditions; I enjoy seeing people on bikes, affordable alternative transports being used.
critique and opinion po,

Simple accounting of the operating costs of the ejeeps including the purchase prices, ROI period, replacements parts (including battery), etc.
Then compare those figures with operating a standard jeepney or multicab public transport.
Try getting an estimate of the amount of money the drivers of jeepneys usually earn at the end of the day. Can the e-jeepney (charging the same fare as jeepneys) make the same or more money for the drivers/operators?
You will also have to consider the limitations of the e-jeepney like maximum driving range in a day, long recharging time between uses, replacement battery pack after a year & half of operating, etc.
From what I know, it is still based on the local government's decision if to adopt the ejeep or not.is there already a national program for the adoption of e-jeeps for testing in their cities?
There is no national program to promote it. I think that is the best because each local city would have it's own special needs and requirements.
regarding the battery life... I think Motolite can think of ways to make this cheaper.
The problem is not "cheaper".
The problem is making a deep cycle battery that is cheaper yet lasts long.
The basic construction of a deep cycle battery is similar to what is found in car batteries but with one big difference, the plates are much thicker. This means more lead is needed. If less lead is used, it will be cheaper but also less charge is stored.
Motolite might make it temporarily cheaper by reducing their profit margins but that is not sustainable in the long run, especially when more electric vehicles are on the road. Would you want to be stuck with a locally made electric car in where you can not afford to buy a replacement battery pack because the only (local) manufacturer decided it will not support the price discounting anymore.
You have to remember Motolite is a company that needs to profit from the sales of their products. They are not a charity.
Studies are not just lacking... they are absent.charging stations.. studies are still lacking,...
Who pays for the electricity? Where will the electricity be sourced? Who maintains the recharging stations?
These are basic questions yet absent in the ejeepney press-kits. Clearly overlooked by overzealous product promoters and politicians alike.
is short, do a life cycle analysis and an economic analysis. do the economic analysis that is being done by environmental economists and not the one used by business and financial people.
hindi ba ejeepneys are supposed to replace diesel PUJs?
that was the original plan of the ejeepney makers diba?
to convince PUJ operators to replace their diesel PUJs with ejeepneys
that plan didnt turn out well
if for every ejeepney sold, one diesel PUJ is taken off the road, i guess that would be considered a success (for environmentalists)
but thing is, for every ejeepney sold, no diesel PUJ is taken off the road
so what exactly is the environmental impact of ejeepneys?
somebody pls enlighten me

this one of the misconceptions with regards to e-jeepneys.
although it doesn't have tailpipe emission, it doesnt necessarily mean it is good for the environment. why? some would argue that the emissions are just transferred from the tailpipe to some other place (most probably in coal-fired power plants). now, the said argument may or may not hold water depending on how clean we produce our electricity.
another one is the battery. we all know batteries have toxic substances in it. the critical factor as already mentioned before is the overall lifespan and mileage of one full charge. if batteries don't last long enough and we don't have the right facilities to recycle or dispose it, we may have adverse environmental impact from its usage.
this has been mentioned before. we can compare the amount of energy used in transporting X number of passengers for T amount of time for conventional jeeps and e-jeepneys. other benefits and costs can be valued for comparison. e-jeepneys should have lower energy requirement, higher benefit and/or lower cost than conventional jeepneys for it to be worth considering.
i know what your saying and i'd like to add more to what you said
but first, environmentalists (like the ejeepney promoter here in the forum) only talk about how "green" ejeepneys are coz they have zero emissions
how about what goes into producing ejeepneys?
all the parts that make up the ejeepneys
they have to be made somewhere, shipped from somewhere
if the parts are made in China, then factories in China have to use energy and materials to produce those parts (China factories are powered by electricity produced by coal-fired power plants)
the parts have to be shipped here inside container vans loaded on ocean freighters which burn fossil fuel
pag dating dito sa Manila port, the parts have to be delivered to the ejeepney assembly plant using diesel trucks
then the energy used to assemble the ejeepneys (Meralco power) isnt all green (not all Meralco power comes from hydroelectric plants)
then the batteries... we all know how toxic lead acid batteries are
then they gotta paint the ejeepneys
is the paint produced in "green" paint factories?
a lot of things that go into producing ejeepneys arent green
so basically, what i'm saying is --
maybe the environment is better off if the ejeepney wasnt produced at all
the ejeepney isnt reducing the carbon footprint of other carbon emitters
buti sana if for the number of ejeepneys sold, an equivalent number of carbon emitters (PUJs) are eliminated
but no carbon emitters are being eliminated
and they keep producing more ejeepneys
the production of ejeepneys has its own carbon footprint
so dagdag carbon pa yan without carbon reduction somewhere else

My take on the e-jeepneys:
Its future:
I hope I'm wrong about this. The way this project is to get going is that there would be interest from the operators and drivers alike. The government cannot force feed them this vehicle wherein they know that it will not be capable of doing what an ordinary jeepney can do. It has to be viable by a long margin against the jeepney.
Probably city governments will subsidize them at first, just like what Makati does. But when they start breaking down and the local government won't give money to have them fixed, the e-jeepney is going the way of the dodo.
Exactly my point. The e-jeepney cannot be financed by the local government or by some non-profit agency forever.
The e-jeepney needs to be economically viable to stand on it's own financially to be even considered a "successful" project.
Yet here we have so manypeople arguing without brains.
the last part of my post will answer you questions. plus the life cycle analysis i've mentioned prior to that.
i am not counting e-jeepneys out as possible solution to some of our pollution problem. we just need to study more of the e-jeepneys we have in our country. lots of studies really because it is not only the environment that will be affected. as what GH also mentioned, the capability to provide effective transportation should also be factored in.
As it stands, I am counting out e-jeepneys as a feasible mass transport system in our cities. It has too many short-comings of a technology used not ready for it's intended application.
In a two year life cycle, it would probably cost more to purchase, run and maintain than a similar capacity conventional diesel powered jeepney.
The promoters & marketeers of the e-jeepney are just using the so-called "green" credentials of an electric vehicle as the only selling point of the e-jeepney. They omit specific facts from getting to the public that would give the people a more balanced view of the ejeepney. They also overstate certain facts as well.
Those facts have already been mentioned in this thread time and time again so I need not to mention them.
More than anything, the ejeepney is more of a political campaign toy than a serious public mass transport system.

I always thought that the best method is an overhaul of all jeepney and bus lines in the metro. Take for example, on certain parts of Shaw Blvd, there are about 6-8 lines plying a part of that road. Tendency is that they all get bottled up.
Redraw all the routes, with consultation with the transport groups. Reduce the number of jeepneys or bus plying lines where the MRT/LRT/LRT 2 lines are existing. Jeepneys will be designated for short trips while buses for long ones. Identify stops, etc.
This could be plotted within 6 months and implemented partially by route over a span of a year.
