What is the voltage of new energy vehicles?

[Emma]

Low-speed electric vehicle battery packs typically have voltages of 48V/60V/72V, while high-speed electric vehicle battery packs generally operate at 380V-560V. Here is additional information: 1. Power battery principle: Power batteries mainly consist of positive electrodes, negative electrodes, electrolytes, separators, etc., requiring high energy density, long lifespan, and reliable safety. Their working principle involves generating electron movement through chemical reactions between positive/negative electrode materials and electrolytes to produce current. During charging (taking lithium batteries as an example), Li﹢ is generated at the positive electrode, moving from the positive electrode through the electrolyte to embed in the negative electrode; the reverse occurs during discharge, with Li﹢ moving from the negative electrode to embed in the positive electrode. 2. Classification: Currently, the three most common types of power batteries are nickel-metal hydride (facing obsolescence), lead-acid (maintained by existing stock), with lithium batteries being the most mainstream currently.
