As we all know, for pure electric vehicles, three-motor system that is, battery pack and BMS battery management system is the most critical, and these three also carry out their duties. For example, the motor determines the maximum speed pure electric vehicle, acceleration and climbing performance, and so on; As for the battery pack, it is the decision of the mileage performance of pure electric vehicles. The different types of battery power, it will certainly affect the power output of the vehicle to a certain extent.
It is well known now traction battery is generally classified into three yuan lithium iron phosphate and the lithium two categories, the two categories of battery internet is not the same as the voltage – controlling the charge and discharge voltage range three yuan lithium battery is 2.5 ~ 4.2V, the charge and discharge of lithium iron phosphate is in the voltage control range 2.0 ~ 3.65V, the lithium battery is three yuan discharge voltage is more higher than lithium iron phosphate.
For a pure electric vehicle, the motor output torque is higher, the stronger the power is obtained. At curb weight, without changing the drag coefficient, low output torque of the motor is proportional to the voltage, the higher voltage that is charged and discharged three yuan lithium batteries, lithium iron phosphate can be compared with a group for more power output.
Therefore, different types of battery, does affect the power output of the vehicle.
