Is it OK to charge the car battery with 12V electric car charger
Theoretically, it takes a long time to charge, but actually it will burn the charger
If you know something about electrical appliances, it's not difficult to achieve
It's just a matter of time before I use the transformer on the black-and-white TV to charge the battery
There is also a small current charge and discharge battery life
Can a 72V electric car be charged in with a 60V charger?
Today, I just changed the charger from 60V to 72V, or did the 60V plug in to show whether it was fully charged or not? Is it OK to change the charger, or did the person not connect the charging wire to me?
The voltage of 60V is too low to be charged. You can change it to a 72V charger
How far can electric cars run
My car is instant. The motor is 350W, and the battery is 48v20a. How far can I run when fully charged? In addition, how many kilowatts of electricity can I charge an hour,
I sell and repair electric vehicles. If it's a new car, it's usually (60-85) km for a single person. The human factors that affect the mileage are: tire pressure, load, starting too fast, braking too frequently, riding speed. The natural factors are: road condition, uphill and downhill, windward. If the above conditions are at the best full speed (85-95) km,
Such as 25 km / h uniform speed (95-110) km
If you are not sure about the range of your car, you can measure it. It is recommended to install an electronic mileage speed counter to make everything clear at a glance. (35-50) yuan
The second question: to see the charger power is generally 150W, 180W, 200W, 220W, 250W. (charger power on the back of the charger or the manual) the calculation method is: (kW / h) suppose your charger power is 250W, charging an hour is 0.25 degree of electricity, and so on, 10 hours is 2.5 degree of electricity
Electric vehicle questions can ask me, can answer for you one by one!
How many revolutions per minute of 500W electric vehicle motor? How many revolutions per minute of 800W electric vehicle motor? I want to buy a motor
In general, the motor speed of 500W and 800W of the same size of the same manufacturer is the same, except for customized, 500W driving current is smaller, of course, climbing force is smaller, suitable for plain areas, 800W motor driving current is larger, climbing force is larger, suitable for hilly areas, hope my reply is helpful
