Global battery production costs have dropped to approximately
US$125/kWh, meaning for
example that car-makers are buying a 100kWh battery pack for $12,500 before they’ve
even dropped it into the car.
Hyundai for its Kona Electric? $13,465.97
before fitment and labour costs. Ouch!

Financial analysts predict the price of battery production will fall below
US$100/kWh by
2025—a benchmark figure that will make the cost to produce EVs on par with conventional
vehicles – and to less than
US$80/kWh by 2030.
