Mitsubishi Pajero EVC – JKR’s EV conversion detailed

The simply concluded Worldwide Electrical Mobility Showcase held in KLCC had no scarcity of shows centred round electrification, however none stood out fairly like this one did, just because it seemed fairly misplaced amidst all the trendy components on name.

Your eyes don’t deceive you. That’s a 1994 Mitsubishi LO49 Pajero, and a public works division (JKR) unit at that. Decked out in a yellow and gray exterior scheme previously, the car was a typical sight within the 90s. After all, greater than three a long time on, it’s now nothing greater than a legacy, of a time passed by.

So why then was this explicit car on present on the Nationwide EV Pavilion space of the occasion? Effectively, that’s as a result of it’s an electrical car, or quite one transformed into an EV by the division. It’s truly the second such car of the sort to endure the conversion into an EV, the primary being a low-powered proof of idea train with a 1993 Pajero again in 2021, your entire venture being accomplished in 41 days.

This one, referred to as the JKR EVC 2, scales the tech up, basically commissioned to reply just a few questions, from gleaning in-depth information about conversion elements to trying on the viability of changing the federal government’s fleet of outdated inner combustion engine (ICE) automobiles to electrical ones. Because it seems, the venture has additionally helped to outline insurance policies, offering priceless info for the EV conversion (EVC) pointers being drafted by the street transport division (JPJ).

Some notes in regards to the Pajero EV. Its diesel mill has been changed by a 90 kW (120 hp) everlasting magnet synchronous reluctance motor which affords round 60 to 65 kW of most steady output and 235 Nm of twist. With energy despatched to the rear wheels, the EVC 2 has a most pace of 120 km/h and accomplishes the 0-60 km/h run in 17 seconds.

The electrical motor is juiced by a 58.36 kWh LiFePo4 (lithium iron phosphate or LFP) battery, which affords the EVC 2 a most journey vary of 200 km. Charging is through AC solely, with a 6.6 kW onboard charger getting the battery from a zero to 90% state of cost in round eight hours.

The battery, which sits on the rear of the car, weighs 400 kg, basically making it a like for like substitute for the discarded engine and different {hardware} on the entrance, with the burden being redistributed to the again of the automobile. There’s round 75 kg of further weight, caused by electrical parts (motor, inverter, DC-to-DC converter), and the suspension has been suitably modified.

Work on the automobile started on September 12 final 12 months, with the venture involving quite a lot of events, together with JKR’s mechanical and electrical division groups in addition to these from collaboration companions EMAR Know-how, UniKL, BateriKu, Vector Labs and Celcom.

Preliminary work – from October to December – consisted of the removing of the Pajero’s engine and doing up the bodywork, together with portray the automobile. Throughout the identical interval, procurement of {hardware} and format design was undertaken, and from March to mid-June, part set up and system integration work was carried out, with working trials starting after that.

By the way, although it’s a prototype, WDP 4161 is totally road-legal, with the division being given a two-year approval to run the car as a R&D testbed by the JPJ. Curiously, the street tax – which is after all zero – for the EVC 2 is vaild all the way in which to 2027, suggesting that street legality for it may prolong all the way in which to then. EV conversions are at present not authorized however authorisation can given by the JPJ in particular instances, similar to for demonstrators or testing.

Whereas fascinating, the initiative to transform the Pajero can be intriguing, provided that the division is related to the development of roads and authorities infrastructure, and EV conversions are nicely off the scope for it. Why then, was the query posed to Megat Zuhairy Megat Tajuddin, former engineering director of JKR, the person behind the electrical Pajero.

“Why is JKR making conversions? Everybody thinks JKR builds roads and authorities buildings and infrastructure. Sure, that’s our core enterprise, however one in all our roles can be sustaining the federal government fleet, and given the nation’s goal of working in direction of a low-carbon footprint, it is just pure to take a look at methods to affect the federal government’s car fleet,” he stated.

“Again in 2021, the division was requested to see the way it may help with that goal. From the JKR perspective, I considered how we may enhance the infrastructure of offering EV chargers in authorities buildings or in areas involving public roads,” he stated.

At that time, Megat stated he wanted an EV to know the necessities. “I didn’t have the finances to purchase a brand new automobile, however we discovered a number of companions, one in all which was trying into EV conversions, and so we determined to discover that avenue,” he stated. As for the selection of the Pajero, it was just about ordained. “After I requested a car for conversion, the JKR workshop handed an inventory of outdated Pajeros that it was keen to supply for the venture,” he defined.

Whereas it began off as an train to ship an EV for figuring out infrastructure necessities, the venture shortly grew to become bigger than the car, evolving into an goal to be sure that EV conversions had been viable and possible in Malaysia. “Though it began out as an inner venture, we now have now been known as to be a part of the nationwide EV initiative as a member for course of and process,” he stated.

Moreover aiding the institution of conversion pointers, he stated it has additionally opened the street for brand new alternatives, particularly for the nation. “One is that so as to perform conversions to required laws, it’s essential to make sure that those that are doing that work are competent,” he said.

As such, coaching turns into essential, and so the concept is to ultimately set up certification for workshops, beginning with JKR’s personal workshops. “It will present a mannequin or reference for any new EVC workshops within the nation, non-public or public,” he stated. He added that conversions would additionally profit native part producers, as elements will certainly be wanted for the exercise.

The price of the Pajero conversion? Round RM150,000, which doesn’t make for a very good enterprise case, however with scale this could simply be halved and ultimately trimmed additional, Megat defined. “After all it has to have economies of scale. Doing one isn’t possible, however go into 1000’s and it’ll alter. The bigger image is the way it will profit native part producers,” he stated.
