The phenomenon of rising electric vehicle battery prices in Indonesia has raised consumer concerns and sparked debate regarding the role of the state in price regulation. This study aims to analyze the authority of the National Consumer Protection Agency (BPKN) in regulating electric vehicle battery prices from the perspective of competition law and consumer protection. The research method employed is normative juridical with statutory and conceptual approaches, analyzing Law No. 8 of 1999 on Consumer Protection, Law No. 5 of 1999 on the Prohibition of Monopolistic Practices and Unfair Business Competition, as well as other related regulations. The findings indicate that BPKN has limited authority in regulating electric vehicle battery prices, with its role being more coordinative and consultative through monitoring and advocacy mechanisms directed at business actors, rather than direct price determination. The authority to set prices is more appropriately vested in the Business Competition Supervisory Commission (KPPU) in cases of monopolistic practices or unfair competition, as well as in relevant technical ministries for strategic goods. This study recommends strengthening inter-agency coordination, enhancing BPKN’s capacity in monitoring the electric vehicle battery market, and drafting specific regulations governing price monitoring mechanisms for batteries as strategic components within the national electric vehicle ecosystem.
