Gimibattery found that there are a lot of friends asking "How many kilowatts of electricity does an electric bike use for a full charge?" or "How many kilowatts of electricity does a 48V-24A electric bicycle battery use for one charge?" Such questions.

So how many kilowatt-hours of electricity does an electric bicycle use for one charge? Generally speaking, a full charge of an electric car should be about 1-1.5 degrees, and the more common one is about 1-1.2 degrees.

1. If calculated in 10 hours, the maximum power consumption of an electric vehicle is about 1.5 degrees.

Generally, a 48v electric bicycle battery needs a charger of about 59v, and the power of this level of charger is 150w (you can see the label on the charger). Generally speaking, 1 kWh = 1000w, 150w = 0.15 kWh per hour (calculate according to the power you see).

Generally, electric vehicles only need a little more than one degree of electricity from a weak current state to a full charge! You can look at your charger for specific situations. For example, if the charger has an output voltage of 55V and an output current of 3~5A, we take 55X3=150W, and it will be fully charged for 10 hours. Then 150X10=1500W, once is one kilowatt-hour, which is 1.5 kilowatt-hours of electricity!

Calculated according to the maximum charging time of 10 hours, it should be 1.5 degrees.

(Note: The above data is based on 48V voltage and 24A current as reference points, please pay attention to it.)

2. The basic formula of charging time for electric bicycles

If you want to estimate the charging time of your electric bicycle, in fact, it mainly depends on the size of the charging current.

The specific method is to use a DC ampere meter in series to measure the current in the loop of the battery and the charger, and then use the formula: electric energy (kWh is the degree) = (current X voltage) X 0.001 X charging time (hours).

Of course, the actual power consumption is more than the calculated result, because the actual efficiency of the charger is less than 100%.
