BQ25185 all-in-one Li-Poly board with 3.3V out 🔋🌞⚡

There are many types of electric vehicles on the market, including 48V, 64V, 74V, 80V, etc. How should we choose?

In terms of technical content, the higher the voltage, the better the performance and economy of electric vehicles. The overall performance of an electric vehicle equipped with five or six batteries is much better than that of an electric vehicle equipped with four batteries. Long-term use is also cheaper and more convenient than an electric vehicle with 48V four batteries. This is also the direction of the future development of electric vehicles. However, the production of high-voltage electric vehicles has a relatively high degree of difficulty, and there are not many manufacturers that can pass the production.

Therefore, most businesses on the market are still selling electric vehicles with four batteries. The price is lower, while the price of electric vehicles equipped with five or six batteries is slightly higher. The reason is very simple. In addition to the technical difficulty factor, high-voltage electric vehicles have more voltage regulating circuits, controllers, motors, and frames. It is much stronger and more durable than a 48V car. Not only is it powerful, fast, long-distance, and long-lasting, but it also has one or two more batteries! The current 48V four-battery electric vehicle, just like the original 36V electric vehicle with three batteries, will complete its historical mission and be replaced by electric vehicles with five or six batteries. Consumers are buying Always be cautious.
