48 V 12 Ah are the two most important electrical parameters of electric vehicle batteries. This is usually indicated on the battery nameplate.
48 V is the nominal voltage of the battery and 12 Ah is the nominal capacity of the battery.
The nominal voltage of the battery (nominal voltage) determines the optimal voltage for connected electrical devices to operate. If it is higher, electrical appliances will easily burn out, and if it is lower, electrical appliances will easily burn out. electrical appliances will not work properly. In addition, the nominal voltage of the battery also provides a reference value for the output voltage of the charger, which should be greater than 48 V.
The nominal capacity (Capacity) of a battery reveals its ability to convert chemical energy into electrical energy and is a unique parameter for battery products. Monity of capacity "A (ampere) H (hour)" shows that it is related to current and time. If discharged with a current of 1A (amp), this battery can continue to discharge for 12 hours when fully charged; if discharged with 4A (ampere), it can continue discharging for 3 hours. Additionally, this parameter also provides an important reference value for the charging current. That is, if the 0.1C rate charging principle is followed, the charging current should be 0.1 times the capacity value and the charging current value = 12 x 0.1 =. 1.2A.
What is the difference between 48v12AH lead acid battery and 48v20AH lithium battery?
How many kilometers can a 48V12Ah electric vehicle battery (48V 12Ah) travel? Let's use the data to give you a detailed answer...
To calculate the cruising range of a 48V 12Ah electric vehicle battery(48 volts 12 amp hours), you need to know the power rating of the electric vehicle's motor. . Let's take a 300W power motor as an example. Calculation for everyone:
Example: The battery of the electric vehicle is 48V 12Ah (48V12Ah), equipped with a 300W motor, the speed of the electric vehicle is 25km/h (the new standard national standard for electric vehicles requires a driving speed of ≦25km/h);
By calculation:
Current size = motor power/voltage size = 300W/ 48V =6.25A, that is, the average operating current of electric vehicles is about 6.25A; driving = battery capacity / average current = 12 Ah / 6.25 A≈2.0 h, that is, the theoretical driving time of an electric vehicle is about 2 hours;
< p>Driving mileage = driving speed * driving time = 25km/h*2h≈50km, i.e. the autTheoretical onomy of electric vehicles is about 50 kilometersThat is to say: 48V12Ah An electric vehicle with an electric vehicle battery and a 300 W motor has a theoretical range of around 50 kilometers.
Of course, the motor power of electric vehicles also includes 400W, 500W, 600W... You can calculate it yourself according to the actual motor power and method calculation above to obtain the theory.Regarding mileage;
In addition, the above is calculated based on theoretical data under ideal conditions. It is difficult to achieve consistency in the actual driving process. After all, every cyclist has different weight, riding habits and riding habits. the roads on which they travel. The climatic environment is also different in different places, so the above theoretical mileage cannot beused only as reference data.
The above is compiled by Platinum Group Lithium Batteries, please refer to
How many kilowatt hours of electricity are needed to charge a 48 volt and 12 volt battery amps. the car from zero to full?
The performance of electrical appliances is exactly the same, but the storage capacity and capacity-to-weight ratio are different. Lead-acid batteries have a higher weight-to-capacity ratio, while lithium batteries have a higher weight-to-capacity ratio. smaller ratio. The 48 volt 12 amp hour lead acid battery has a storage capacity of 48*12 = 576 watts, and the lithium battery has a storage capacity of 960 watt hours, which is 384 watt hours more than the lead acid battery. acid battery.
A 48v12ah battery requires 0.576 kilowatt hours of electricity to fully charge. 48v12ah represents the battery parameters, 48v represents the nominal voltage of the battery and 12ah represents the nominal capacity of the battery. battery, it is recommended to choose products from regular manufacturers. There is quality assurance. Notes on using batteries:
1. Lithium batteries do not need to be charged for a long time. Once fully charged, the power plug can be unplugged.
2. The battery cannot be charged. The battery may be fully charged and cannot be charged. The original power adapter may not be used and the third-party charger may be incompatible. with the device. The device battery may be damaged. It is recommended to contact after-sales service.
3. The mobile phone cannot be turned on. The battery may be damaged.
4. The battery has a lifespan and should be replaced in time to avoid affecting the experienceence of the device. On iPhone, you can check the maximum battery capacity.
1.08 kWh.
There are many types of electric vehicle batteries, including 48V, 60V, etc. However, due to the implementation of the new national standard, there are clear restrictions on battery voltage. Therefore, taking a 48V20AH battery as an example, its average charging voltage is about 51.6V. Additionally, the power required to be charged is 1.05 times the power released, so one charge consumes approximately 1.08 kWh (power consumed = average charging voltage*). Nominal battery capacity*1.05).
After the electric vehicle battery is completely discharged, it can be fully charged in 8-10 hours. This means that the power consumption of its 48V20AH battery is about 0.1 to 0.13 degrees per hour, while that of the 48V12AH battery. consumes about 0.1 to 0.13 degreesCelsius per hour. Power consumption is about 0.06 to 0.08 degrees.
