Battery-electric vehicles (BEV) have emerged as a favoured technology solution to mitigate transport greenhouse gas (GHG) emissions in many non-Annex 1 countries, including India. GHG mitigation potentials of electric 4-wheelers in India depend critically on when and where they are charged: 40% reduction in the north-eastern states and more than 15% increase in the eastern/western regions today, with higher overall GHGs emitted when charged overnight and in the summer. Self-charging gasoline-electric hybrids can lead to 33% GHG reductions, though they haven't been fully considered a mitigation option in India. Electric 2-wheelers can already enable a 20% reduction in GHG emissions given their small battery size and superior efficiency. India's electrification plan demands up to 125GWh of annual battery capacities by 2030, nearly 10% of projected worldwide productions. India requires a phased electrification with a near-term focus on 2-wheelers and a clear trajectory to phase-out coal-power for an organised mobility transition.
电池电动汽车 (BEV) 已成为缓解许多非附件 1 国家（包括印度）交通温室气体 (GHG) 排放的首选技术解决方案。印度电动四轮车的温室气体减排潜力取决于何时何地充电：今天，东北部各州的减排量为 40%，东部/西部地区的减排量增加了 15%以上，而夜间和夏季充电会导致更高的总体温室气体排放。自充电汽油-电动混合动力车可以减少 33%的温室气体排放，但在印度尚未被完全视为一种缓解选择。电动两轮车已经可以通过其较小的电池尺寸和更高的效率实现 20%的温室气体减排。印度的电气化计划要求到 2030 年每年达到 125GWh 的电池容量，占全球预计产量的近 10%。印度需要分阶段实现电气化，近期重点是两轮车，并制定明确的轨迹，逐步淘汰燃煤发电，实现有序的交通转型。
