Q0065
Yes, but smart charging should come before widespread vehicle-to-grid export. Malaysia can first manage when EVs charge so they avoid local peaks and absorb lower-cost or renewable electricity. Bidirectional vehicles could later supply buildings or the grid, but this needs compatible cars and chargers, communications standards, approved connection rules, aggregation, compensation and evidence that battery wear and driver inconvenience remain acceptable.
EV batteries will represent a large pool of storage that is purchased primarily for transport. Coordinating charging could reduce grid stress and renewable curtailment, while uncontrolled charging could create new evening peaks and accelerate local network upgrades.
Unidirectional smart charging can delay, slow or accelerate charging within the driver's required departure time and minimum state of charge. It is simpler than bidirectional operation and can respond to tariffs or network limits.
Vehicle-to-load powers individual devices. Vehicle-to-home or building supports onsite loads and backup. Vehicle-to-grid exports through an approved connection and may provide energy, frequency response or local network relief.
The vehicle must be plugged in, have sufficient charge and remain available long enough. Workplace fleets, buses, delivery vehicles and cars parked overnight may be more predictable than a dispersed private fleet.
Compatible vehicles, bidirectional chargers, metering, communication protocols, charger-management systems and aggregator platforms must exchange state of charge, departure time, grid signals and safe operating limits.
Extra cycling can cause degradation, although managed operation may avoid damaging states or temperatures. Owners need compensation that exceeds incremental wear, conversion loss and inconvenience, supported by warranty terms.
Charging flexibility can reduce transformer and feeder peaks. Export could help during a constraint but can also create reverse flow or voltage problems. Programmes need location-aware control rather than a national price signal alone.
