The distance an electric vehicle can travel depends on the power of the engine. The motor power is 1800W and the battery is 60v72AH. The maximum theoretical range can reach 86.4 kilometers.
Method for calculating theoretical mileage:
1. Uniform average current = power/voltage = 1800 W/60 V = 30 A.
2. Driving time = battery capacity/average current = 72AH/25A = 2.88 hours.
3. Calculated at a speed of 55 kilometers per hour, the theoretical mileage = 2.88*30=86.4 kilometers.
Influencing factors
Lithium batteries can generally be charged and discharged 300 to 500 times. It is better to partially discharge lithium batteries than to fully discharge them, and to avoid frequent full discharges. Once the battery leaves the production line, the clock starts ticking. Whether you use it or not, the battery lifeeries lithium battery only lasts the first few years.
The decrease in battery capacity is due to an increase in internal resistance caused by oxidation (which is the main cause of the decrease in battery capacity). Eventually, the cell's resistance reaches a point where, even though the battery is fully charged, it is unable to release the stored energy. The aging rate of lithium batteries is determined by temperature and state of charge. The table below illustrates the reduction in battery capacity for both settings.
The 60 volt, 180 Ah lithium battery of the Sanqianw motor has a range of between 4O and 5O kilometers. According to the query information, the rated power of the 3000 watt motor is greater than the rated power of the 60 V battery when the 60 V battery drives the 3000 watt motor, because the rated power of the motor3000 watts is higher. than the rated power of the battery 60V, the driving speed of the battery is relatively fast, but the cruising range of the battery is relatively long, and the longest range can be between 40 and 50 kilometers.
