Mileage anxiety is still the main concern of drivers who have a wait-and-see attitude towards incorporating fully electric vehicles into their lives. Even experienced users of battery electric vehicles will take more foresight when using electric vehicles for long-distance trips in cities where charging facilities are scarce. Sexual planning.

In some cases, charging points cannot be included in the above plan, and this is where backup measures are needed. When the gasoline or diesel engine vehicle runs out or is about to run out of fuel and the gas station is not close enough, oil tanks can usually be used.

Most people have mastered new skills and craftsmanship at all stages of our pandemic-driven lockdown. Electric car enthusiast Datuk Abdul Jafar Rumli designed a flat battery rescue form for BEV—— EV Jerry Can, started the project in June this year, completely self-funded.

Ghaffar first entered the government department in 1979 and joined the Tun Ismail Atomic Research Center (PUSPATI) as a researcher. In 1984, he was appointed as the head of the nuclear technology project. Ghaffar served as the director of the National Defense Science and Technology Center and became director of the National Defense Science and Technology Institute (STRIDE) in 2002 until his retirement. year 2013.

The EV Jerry Can prototype is essentially a “very large power bank” for electric vehicles, which is virtually displayed to the community of electric car enthusiasts through video calls. The device takes the form of a box, about the size of a trolley bag carried by an airline.

Ghaffar said it is installed in a series of 32650 LFP (lithium iron phosphate) batteries, and a 500 W external charger will fully charge the EV Jerry Can (2.4 kWh) in about four to five hours. The connection with the electric vehicle adopts the CEE 16 protocol, and then connects to the portable EVSE and type 1 or type 2 connector, depending on the needs of the vehicle.Jafar Reno Zoe EV uses type 2 connectors.

Although the battery pack has a rated power of 2.4 kWh, Ghaffar said that due to some waste batteries, he could not get the maximum value from the battery pack. However, early measurements indicate that the AC to DC conversion efficiency is 82%, which should produce approximately 2 kWh. Based on Zoe’s energy consumption rate of 140 Wh per kilometer, the 2 kWh provided by Jerry Can should provide an additional 14 to 15 kilometers of cruising range.

Admittedly, 14 or 15 kilometers is not much, and it is really to get you to the more important supply port. Looking ahead, Ghaffar is developing his second supplementary battery pack, which will use 16 prismatic batteries instead of the 128 cylindrical 32650 batteries currently weighing 35.4 kg.

The second battery pack will not have its own inverter, but will be paired with the inverter of the existing battery pack. Ghaffar decided to limit the capacity of the second battery pack to 2.5 kWh to reduce the weight to 28 kg, instead of the previous 4 or 5 kWh capacity target, which weighed 37 kg.

In theory, this will provide a total battery capacity of 4.9 kWh, and use a second battery pack to double the additional cruising range of 14 to 15 kilometers to about 30 kilometers. However, this must not be consumed all at once, but in order-because the voltage in each package may be different, for safety reasons, you need to use one at a time, Ghaffar said.

So far, the cost of developing this battery pack is RM3,500. Will it eventually be sold as an end-user product? “I’m not going to commercialize it, although I’ve talked to some companies to see if they’re keen,” Ghaffar said. He is also considering renting out these battery packs or providing them to vehicle recycling companies for use in electric vehicles. Emergency charging on the roadside. He said it “would be cheaper than a trailer.”
