[SIZE="4"]E-jeepney and Jack[/SIZE]

IN a month or so, a new kind of public jeepney will be plying the streets of Bacolod City. This costs about P380,000 each, is made of fiberglass, seats only 13 including driver and doesn’t need gasoline to run. It’s an e-jeepney.

E-jeepney is an electric-powered jeepney that will debut in the streets of Bacolod, a city where the latest automobile models cruise. If you want to find out what’s new in the auto industry, you’ll find your answer in this city that’s 20 flying minutes from Cebu.

Since it does not run on gasoline or diesel, the e-jeepney is dependent on rechargeable batteries. For it to go an 80- to 100-kilometer trip a day, it needs to be charged for eight hours.

So what happens when the battery is almost drained, does the e-jeepney stop in the middle of the road, or does it warn the driver that it can go only for this distance so he can tell the passengers, “Guys, this is where you get off now. It’s only about two kilometers to your destination anyway and walking will do you good.”?

Green Renewable Independent Power Producer Inc. (GRIPP), the private sector group that is behind the e-jeepney endeavor, wants to test the viability and sustainability of the electric-powered mass transport in Bacolod before it brings the vehicle to other cities, maybe Cebu.

I called up Jack Jakosalem, the Cebu City councilor who seems to have an answer to whatever question I ask him, be it the distance between his house in Maria Luisa and the moon or a behavioral analysis of the mayor. Jack heads the Council committee on transportation, energy, utilities and communication.

Do you think an electric-powered jeepney can work in Cebu, Jack?

He answered: We’re moving towards that direction—using vehicles with hybrid engines, partly gasoline, partly energy. They cause less strain on our environment and our pockets. But so far, it’s still private vehicles, no public transport yet. The private cars running on hybrid engines are expensive.

Later, he texted: With the inventive instinct of the Filipinos and the jeepney being a Filipino concept, I’m sure they will find a way to make the jeepney a cheaper and more maintenance-free mode of public transportation eventually.”

Off the cuff, I think the e-jeepney might be environmentally friendly but it might not be practical for Cebu City where the increasing number of vehicles is aggravating the traffic congestion. If the e-jeepney seats only 12 passengers (I think its Chinese makers have the average Asian size in mind), then it has the size of a multicab. What Cebu needs is a mass transport similar to the KMK buses that accommodate passengers of three to four 12F jeepneys.

There is more to the e-jeep than passenger sizes, fiberglass body and probably a crocheted sign of “God knows Hudas not pay.” It will be powered by electricity that is produced from waste. The e-jeep will be charged by batteries that will be charged at a power plant.

As described in news reports, the power plant consists of a generator, a high solid anaerobic digester and gas engine. Organic refuse will be emptied into the digester where this will be dissolved and converted into gas, which in turn will be pumped into an engine that will now produce the electricity. A physicist or a science teacher, or maybe even Jack, can explain this process better than I do.

When I visit Sun.Star Bacolod next month, I’ll try the e-jeepney, but I’ll be crossing my fingers that I get to my destination before it goes low-batt.

Interesting. With current locally available battery technology, I don't know how well this will work, but it's interesting.

[jundogg]

another good idea when it comes to philippine automotive industry.
big savings on petroleum, but needs a lot of power!

ive seen one like this on tv, i think it's in australia.
battery powered delivery mini-van. more than a dozen of car batteries are used, connected in series, to power up and make the whole vehicle run.

recharge stations along the way, built-in "super-chargers" or solar panels could help. 8 hours of charging might waste a lot of time for the driver to meet his boundary.

I believe that this is also the same e-jeepney na ilalaunch sa makati sa june 22, nakausap ko people from greenpeace and i am waiting for their invitation para tsikot can cover the said event.

sa kwento nila sakin, 2 hours charging nito, good for 6 to 8 hours na sya, dumating na yata sya the other day from china. ang cost daw nito is around 400k. Magkakaroon din ng 1 week public showing ito sa makati.

[drey]

so di ito Pinoy - made?

[jedi]

* drey, yes definitely, di sya pinoy made

[architect]

Hmmm. Maybe we can install solar panels on the roof of the Tableta as well - eTableta?

[jpdm]

* drey, yes definitely, di sya pinoy made

Ay ganun po?di bale gawa na lang pinoy version.maraming magagaling na manufacturer ng AUV, jeepney sa Iloilo, Bacolod at Cebu. Magaganda at matibay pa. surplus nga lang engine. Sana makipag-collaborate din MVPMAP dito sa mga ito.

[safeorigin]

e-Tableta, eh? hmmm... parang vw van ng hippy siguro kakalabasan nun.

[mazdamazda]

Hmmm... not really a new thing... just plop in a few lead-acid batteries and you have your electric vehicle ready. The problem with lead-acid batteries is that they take up a lot of time to charge and that they are bulky & heavy.

Electric vehicles might be more feasible to use for low load applications like for postal & delivery services.

[ghosthunter]

The range of the e-jeepney's batteries might be an issue since it will only go 80 to 100km per charge. But you can extend the use simply by swapping the batteries for a freshly charged set. If they can develop a quick swap "battery pack" system (something you can do in less than 15 minutes with only one person), it would probably solve the practical range problem.

BTW, is that 80 to 100km range based on regular car batteries or deep cycle storage cell batteries?

[drey]

I saw it already...

2 units parked in front of Mayor Binays mansion this morning... Dunno if its still there tho.

Maliit sya.

[russpogi]

I saw that running along Ayala Ave. around 8am with police escorts. The pictures are on the front page of some of today's papers.

[fukengruven]

mas matagal siguro battery kung deep cycle nga to.. kaya lang dagdag mahal :D

correct sir jedi ..nandoon nga mga taga greenpeace..pati si richard gutierrez at georgina wilson( naka green shirts pa) ..nag drive sila ng e-jeepney

Correct Ghosthunter minor solution can be made 'BATTERY PACK' system. And can be charged by photovoltaic solar panel for whole day...No fossil fuel involved and electricity cost...TSK! TSK! TSK! pag nagkataon bagsak ang sales ng diesel ng big 4 oil company...multiply how many jeep rely on diesel suddenly zero sa electric jeepney....Sana walang pulitikahan na mangyari matuloy na ito at ma-improve pa. Para naman bumaba ang pamasahe ng mga kababayan natin. At higit sa lahat mabawasan ang pulusyon sa manila.

kaya lang sir, all imported from China ata.kaya medyo sa tingin ko tagilid ito.mahirap i-maintain yan. Of course, malaking bagay yang project na yan ng Makati at Green peace, very laudable pero untested ang technology.

tapos ginawa pang pampasahero, naku baka di tumagal. mga available na electric vehicles abroad e limited lang ang passengers, bugbog sarado yan. warak kaagad makina.

Dapat, PHUV na lang na may eco-friendly engine powered by biodiesel or CNG.

Making the E-Jeepney a roadway powered electric vehicle can solve the battery issue. In an RPEV the batteries are charged with power from electrical coils embedded in some parts of the road (like at jeepney stops or at traffic lights).

The infrastructure required for this type of project is too expensive. The better solution is the swappable battery pack. This gives the e-jeeps flexibility in their routes as long as the recharging base station is within reasonable distance. A single recharging base station can service e-jeeps from multiple routes as compared to the cost required to install inductive changing systems in the roadway. Not to mention potential health risks due to EMF radiation, especially to unborn babies.

I know the swappable battery pack is NOT the final solution but a stop-gap solution until improvements in electric battery technology (and costs) and electric motor efficiencies can catch up.

Here is one possible way to increase the e-jeep's system efficiency. A rubber band to store kinetic energy when the e-jeep uses it's brakes to stop. We know the e-jeep will be doing stop & go operations. A "rubber band" will store the kinetic energy and release it to give the e-jeep an initial acceleration to around 15 to 20 kph. This saves battery energy used up to move the e-jeep from a standing start. BTW, the system might not use actual rubber bands, it could be a spring steel wound springs like those used in pull back toy cars.

[donbuggy]

Or a flywheel to store the energy.
