1. Electric vehicles (EVs) primarily rely on electricity stored in batteries as their power source. No direct gasoline or diesel combustion involved!
2. The most common battery type used in EVs today is lithium-ion (Li-ion). They offer high energy density (pack more power in less space), good efficiency, and long lifespans.
3. While Li-ion reigns supreme, research continues on alternatives like solid-state batteries, promising even higher energy density and faster charging times.
4. Some early EVs and niche applications still use nickel-metal hydride (NiMH) batteries, known for durability and longevity but lower energy density than Li-ion.
5. Lead-acid batteries, like those in starter batteries, aren't widely used in EVs due to their lower capacity and weight. However, they may find use in specific applications like micro-mobility.
6. The battery pack in an EV consists of numerous individual Li-ion cells connected in series and parallel to achieve the desired voltage and power output.
7. Battery management systems (BMS) are crucial for monitoring and regulating individual cells within the pack, ensuring safety and optimal performance.
8. Different EV models use varying battery capacities impacting range, with larger packs enabling longer distances between charges.
9. Charging infrastructure plays a crucial role in EV adoption, with options like home chargers, public charging stations, and even ultra-fast DC chargers becoming increasingly available.
10. While Li-ion batteries dominate now, the future of EV power sources remains open, with exciting developments in solid-state and other technologies on the horizon.
