It is undeniable the EV is future trend of automotive industry. The current concern mostly because of charging infra and range problem but these can be solved in near future.
Those who concern of charging infra, mind to ask where are the places the TNB not reachable? If you talk about jungle then don't buy it if you live long in jungle. As long as got 3 pin plug we can use it to charge the EV car, just matter of how long it takes. 1hr can give 3kwh, yes it will take about 24 hours to get about 70kwh but at least it still can charge. If we install 7.6kwh charger at home it will shorten by half.
Concern about range then we have to think about the EV battery technology. In the past there is only lithium available but battery tech move rapidly. There are many innovation on battery with many variants such as lithium, LFP, LMFP, sodium, semi-solid state and in the future solid-state battery. For ICE people talk about engine tech but in EV people concern about the battery tech.

Miti is expecting 4000 charging points this year. Imaging 5 years time it will be at least over 20k charging points or maybe even surpass 30k points. This is for public and not include private charging point for household. I predict most if not all petrol stations will ready with charging port in future.

Many people keep complaining 400km range is too low should have at least 500km or even 700km range. I guess this might achievable in future. But for now 400km WLTP is reasonable. How many people really travel 150km per day, probably less than 10%. Some concern KL bad traffic and cause more energy loss if driving EV. The concept of EV is almost upside down compare to ICE. EV give more range in city traffic and less range in highway cruise. In bad traffic the energy loss more in ICE and EV is less. ICE in bad traffic the engine is keep running to pull the fans belt to provide electricity to power electronic and also aircond. 2.0L idle for 1 hour is about 0.16 gallon (0.6L) without aircond. Assuming with aircond is 0.20 gallon per hour or 0.75L, it will be RM1.54 per hour stuck in traffic. https://www.energy.gov/eere/vehicles/fact-8...diesel-vehiclesWhile in EV the most consuming energy is aircond during idle or bad traffic. Imagine household non-inverted 1hp aircond is almost 1kwh, but car cabin is much smaller. Even if include all electronic stuffs and makes it at 1kwh during idle or bad traffic, it is only RM 0.571 per hour. So driving in City and bad traffic the EV is much saver than petrol even though Malaysia petrol is cheap. This post has been edited by autodriver: May 8 2023, 10:36 AM

QUOTE(EnergyAnalyst @ May 9 2023, 10:45 AM) Yet many perceived hurdles will remain hurdles perceived. To draw a parallel, many home dwellers has installed solar panel on their roof tops, and ended up paying much lesser bill (in some cases even zero bill) but many others on the other hand are still seceptical , saying it is upfront cost intensive, solar system will be less efficient in harvesting overtime, wait for technology to be more efficient first lah blah blah blah. Not knowing or being sceptical about the incentives and such financing scheme offered even by TNB subsidiary company and not taking advantage of it. Wait and wait and wait. Meanwhile complain about this and that, e.g. why only the rich get richer, complain about why electricity bill has gone up (after smart meters replacement rolled out) , complain about all these EVs are fancy flashy things only meant for the privileged yada yada yada. The majority mindset is only seeing problem and enlarge it instead of taking it as an opportunity. In Malaysia still many landed house which are extremely suitable to install solar panel. Some will say Malaysia although got hot days but also many raining days. There are getting more and more residents in European and US are installing solar panel and these countries are 4 seasons which has few sunny days like Malaysia. So if these 4 season countries getting more solar panel why not Malaysia. Installing solar panel in Malaysia can apply subsidy from TNB. Basically we only need to pay low electricity bill for household plus charging for EV car. No doubt many people wanted a range of 600km per charge but in reality how many of us really go pump petrol after travel of 500km. I strongly believe less than 10% people really need travel 500km in short time (1 or 2 days driving range). If in city or town drive 1 day travel most likely 100km or below and 1 full charge will at least last 3 days (min 60kwh battery size). If battery drop half after 2 days just charge it at night. Example like Telsa charge cycley is 1500 times. Even if we charge every 2 days the battery expect to last for 8 years. How many of us really charge every 2 days once? We are most likely need charge after 3 or 4 days usage for daily town drive.
