Mitsubishi Motors Corp (MMC) announced Oct 3, 2019, that it has participated in an energy management test in the Sumba Island, East Nusa Tenggara Province, Indonesia.

An electric vehicle (EV) will be operated by using solar electricity. The aim of the test is to find a way to efficiently use energy in an isolated island where it is difficult to secure gasoline.

The test has been conducted by Kyudenko Co Ltd and the Agency for the Assessment and Application of Technology of Indonesia (BPPT) as a project subsidized by Japan's Ministry of the Environment since December 2017.

Electricity generated at an existing solar power plant set up by the Indonesian government is stabilized with Kyudenko's lead-acid battery and energy management system (EMS), and a certain amount of electricity is supplied to the power grid of the island.

MMC donated two units of the "i-MiEV" EV in February 2018, eight units of the "Outlander PHEV" plug-in hybrid vehicle (PHEV) and four units of a rapid charger to the Indonesian government.

Among them, one unit of the i-MiEV and one unit of the rapid charger are used in the island. The rapid charger is connected to the power grid of the island, and the amount of electricity used for charging the EV is covered by solar electricity via Kyudenko's EMS.

In Indonesia, there are several thousands of inhabited islands, many of which use old-fashioned diesel generators. The output of the solar power plant used for the test is 500kW, and the capacity of the lead-acid battery is 1,152kWh. The ratio of renewable energy will be increased by using Kyudenko's EMS, contributing to stable operation of the power grid of the island, which often goes down.
