What does 72v mean?

[DiIsabelle]

72v refers to the voltage of the power battery being 72v, which means the voltage supplied to the motor is 72v. The 72v voltage output is typically composed of six lead-acid batteries, with each battery having a voltage of 12v, resulting in a combined 72v battery pack. The functions of the battery are: 1. When starting the engine, the battery supplies power to the starting system, ignition system, and electronic fuel injection system; 2. When the engine is stopped or at low idle, it powers the vehicle's electrical equipment; 3. When the generator's output is insufficient, it can assist in supplying power to the electrical equipment; 4. It mitigates voltage surges in the electrical system, protecting the vehicle's electronic devices; 5. It can store excess electricity generated by the alternator.

When I saw the 72v label in my electric vehicle manual, I initially thought it was some brand or model. Later, I realized it was a voltage unit, indicating the entire battery system operates at 72 volts. This type of vehicle accelerates faster and has better climbing power. My 72v electric motorcycle can reach a top speed of around 60 kilometers per hour. Generally, higher battery voltage also means a longer range, but the charging time is slightly longer. For daily use, it's essential to pair it with a proper controller to avoid overheating caused by excessive current. When modifying, be cautious with 72v kits, as improper matching can affect the vehicle's lifespan and safety.

72V is quite common in the electric vehicle field. My understanding is that it refers to a 72-volt voltage system, which is core to vehicle performance. Higher voltage allows the motor to operate more efficiently with greater power output and lower current loss, significantly improving acceleration and climbing ability. For daily commuting, choosing a 72V model is more cost-effective, offering about 20% longer range than 48V vehicles. However, attention must be paid to wire insulation during installation to prevent short-circuit risks. Excessively high voltage may also increase maintenance costs, so regular maintenance testing is recommended.
