Agus Tjahajana Wirakusumah, Special Staff to the Minister of Energy and Mineral Resources (ESDM) for the Acceleration of Industrial Development for the ESDM sector, said that the standardization of EV batteries and infrastructure must refer to the results of an agreement between three parties such as producers, consumers and the government. So far, standardization still does not exist.

He explained that battery standardization and EV support facilities would be uniform, such as battery performance benchmarks.

"Determining the standard size of the battery is a bit difficult, because the types of motors vary," he said.

Evvy Kartini, founder of the National Battery Research Institute (NBRI) said uniformity in battery types must start from the cell level to the battery pack. Battery pack is a combination of a number of battery cells. In general, electric motors have 80 battery cells combined into a set of battery packs.

According to her, this uniformity must target the volume, weight and capacity of the battery so that it does not cause a difference in the battery, especially when recharging at SPBKLU.

She added, the issuance of regulations regarding battery standardization was effective in increasing sales of electric vehicles, especially for electric motorbikes and converted electric motorbikes.

This uniformity is considered urgent to reduce the concerns of electric motorbike users who want to increase their electric battery power.

"Our study shows that currently there are 20 different lithium-ion batteries. Both in terms of volume, output capacity and performance," said Evvy, on August 8, 2023.

She further added, Indonesia actually already has standard battery standards. However, this standardization is still not binding and only regulates basic things, and does not regulate fundamental aspects such as weight or battery load.

For this reason, Indonesia needs to refer to countries such as South Korea and India as countries that are more advanced in uniforming electric vehicle batteries.

Currently, South Korea has stipulated a battery that can be installed in each electric motorbike, with a maximum battery weight of 12 kilograms (kg) so that it is friendly for women who want to exchange batteries at SPBKLU.

"This standardization needs to be regulated in regulations passed by the government so that it has strong binding power. Connectors for charging must also be regulated," she said.
