By 2040, the country is expected to have 1.5 million electric vehicles (EVs), the Dewan Rakyat was told.
The aim, according to Minister of Natural Resources, Environment, and Climate Change Nik Nazmi Nik Ahmad, follows a global shift to EVs from internal combustion engines (ICEs) that use petrol and diesel.
He said that the new goal is higher than the previous goal of 90,000 EVs by 2040 set by the Planning and Implementation Committee for Electricity Supply and Tariff (JPPPET).

Besides range anxiety – the concern about how far you can go on a fully charged battery pack – has been on the minds of people who consider hybrids or electric vehicles, the other issue has also been the cost of the battery pack itself. In the early years, when the technology was still young, battery packs were very expensive and discouraged many people. But there has been constant advancement of the technologies, along with prices coming down, although they still are much more expensive than the small batteries that you see in the engine bay.
The battery packs have generally been reliable and how long they last has depended on many factors, both environmental as well as driving. It’s like batteries in laptops or mobilephones – some people enjoy a long service life while others may have to replace them within a couple of years when they cannot hold their charge properly.
PHEVs sold since December 2015 are covered
To give customers peace of mind, many companies have offered longer warranties on the battery packs. Volvo Car Malaysia announced its extended warranty in March 2020 but the coverage was only for models in its Plug-in Hybrid Electric Vehicle (PHEV) range registered from January 1, 2020.
Now the company has extended the coverage to all Volvo PHEVs purchased since December 3, 2015 when the XC90 T8 PHEV was launched in Malaysia. The company says that this has been prompted by ‘the enthusiastic response from customers and realising the positive impact that long-term electrification can bring to the environment’.
“As we continue our journey into sustainability, we are happy to announce this new, extended warranty coverage for our customers who have purchased any Volvo PHEVs since the launch of our first XC90 PHEV in Malaysia. This is our way of showing gratitude to the early adopters and also for those who are striving to make a more sustainable decision,” said Nalin Jain, MD of Volvo Car Malaysia.
The Volvo range of PHEVs for the Malaysian market consists of the S60 T8, XC60 T8, XC90 T8, and S90 T8. Prices range from RM295,888 to RM409,888 (excluding insurance).

When people started buying hybrids and electric vehicles, the issue of battery pack costs was not so apparent. Perhaps it was due to having used batteries in conventional cars which could last a few years and replaced periodically at a relatively low cost. However, the battery pack in an electrified vehicle (hybrid/EV) is different from the typical 12V battery in millions of vehicles. While the small battery in the engine bay provides electricity to start the engine primarily, the battery pack in an electrified vehicle actually powers the vehicle.
Due to the need to store large amounts of electrical energy, the battery packs have to be bigger and use more advanced technologies and materials. Conventional 12V batteries have typically used a lead-acid combination and though improved over the years, their process of generating electricity through chemical reaction has not changed.
Because battery pack technology is still evolving as storage capacity increases, the cost of the new technology is still high, not to mention the economies of scale are still lower than for conventional lead-acid batteries. This means they cost much more and for the early owners of electrified vehicles, there was the sudden shock of discovering that the cost of replacement was very high.
In Malaysia, depending on the model, the price was RM7,000 upwards. This led to reduced appeal for electrified vehicles and in order to provide peace of mind, the companies selling such vehicles began to offer a separate warranty on the battery pack which was longer than the factory warranty for the vehicle.
The prices have come down a bit and the battery pack for some Honda models sold in Malaysia is around RM5,500. Like those 12V batteries, the battery pack can last a while though there is no specific service life promised. Extreme operating conditions or rare system problems can shorten the life which is why the warranty is useful. But this does have an effect on resale value since the next owner would have to consider the added cost of replacement at some point in time.
To address this key concern for electrified vehicle ownership, BMW’s high-voltage battery presents solutions to concerns around repair and maintenance by developing their batteries where single modules are replaceable. In the case of a lithium-ion battery pack (increasingly used) that houses multiple modules, there are multiple cells.
In most cases, if a battery pack starts to have problems or has reached the end of its service life, the whole unit has to be replaced – at considerable cost. However, the high-voltage battery pack used in BMWs does not necessarily require this expensive approach.
In the 530e M Sport, for example, the battery pack gas up to 6 cell modules. Should one of the modules be faulty, it does not mean the whole battery pack needs to be replace. Just that module can be changed and the cost is RM5,000 per cell. Although built to last the lifetime of the vehicle, BMW Group Malaysia still offers a comprehensive warranty coverage of 6 years/100,000 kms for the battery packs in its vehicles which should give peace of mind to owners.
The lightweight battery pack is capable of storing a great deal of energy, giving the 530e M Sport a maximum output of 83 kW which can get it to a maximum speed of 120 km/h in full electric driving. Recharging time is dependent on the type of system used but said to be under 3 hours with the BMW i Wallbox, with a fully charged battery pack giving an all-electric range of up to 40 kms.
BMW’s high-voltage battery technology is available in the plug-in hybrid variants of the 5-Series, 7-Series, as well as the all-electric i3s and the MINI Plug-In Hybrid.
