Generally, for a higher-power motor, a higher voltage is preferable. The selection of battery parameters is based on the range required for the vehicle and the capacity to provide peak discharge current and the duration for the peak current. Battery capacity (Ah or KWh) = (Mileage Requirement / Avg speed) x Avg current or power consumption.
Battery capacity is based on the desired operational run time of the equipment between recharging cycles and is simply the amount of charge a battery can hold. The standard measure for battery capacity is milliampere-hours (mAh) or amp-hours (Ah), which indicates how long the battery will last based on the current it outputs.
So scientifically it is denoted as only Ah. For example, the Mahindra e20 has 10kWh energy stored in the battery. It can deliver approx. 208 Ampere current for one hour, at a rated voltage of 48V. How battery capacity affects range? A car’s range depends on its battery’s capacity and efficiency of use.
Recently announced by CATL that its batteries have a density of over 290Wh/litre for LFP chemistry and over 450Wh/litre for NCM chemistry. Power gives acceleration to the car and maintains it at a given speed. Though mechanically power is the product of torque and rpm.
The way the power capability is measured is in C 's. A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A. The amount of current a battery 'likes' to have drawn from it is measured in C. The higher the C the more current you can draw from the battery without exhausting it prematurely.
One key motor performance parameter to consider in a battery-powered application is efficiency. Maximizing motor efficiency helps minimize the required power capacity and hence the size and cost of the battery solution. For this reason, brushless DC (BLDC) motors are preferred over brushed DC motors but are typically higher in price.

In this case, you would want to have 2 Flooded Lead Acid or AGM batteries wired in parallel in order to have enough battery capacity to meet your power consumption needs. Factors Affecting Battery Capacity. Various factors outside of the type of battery can impact battery capacity, including temperature, discharge rate and age. These factors ...
Typically, starting uses less than three percent of the battery capacity. For this reason, automotive batteries are designed to deliver maximum current for a short period of time. They are sometimes referred to as "SLI batteries" for this reason, for starting, lighting and ignition.
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh ). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours).
For example, if a battery has a capacity of 100 Wh, it can deliver 100 watts of power for one hour, or 50 watts for two hours. Measuring Techniques. When it comes to measuring battery capacity, there are several techniques that you can use. Using a Multimeter. One of the simplest ways to measure battery capacity is by using a multimeter.
Because the motor voltage is always lower than the battery voltage, but the power is the same, then the current is higher. If the controller PWM was 20%, then the motor …
Because the motor voltage is always lower than the battery voltage, but the power is the same, then the current is higher. If the controller PWM was 20%, then the motor voltage would be 20V and the current 50A, for the same 1kW of power.
Battery capacity or Energy capacity is the ability of a battery to deliver a certain amount of power over a while. It is measured in kilowatt-hours (product of voltage and ampere-hours). It determines the energy available to the motor and other elements.
In practice, this means that a 48V battery will deliver power to an e-bike''s motor faster than a 36V system. As such, the motor of a 48V system does not have to wait to access and use the power it receives, and will also get more power in the same amount of time. This means that – provided all other factors are the same – a motor receiving power from a higher …
For example, if we were to take a 10000mAh power bank, its actual capacity would be: 5V capacity= (3.7V * 10000mAh) / 5V = 7400mAh. As you can see, the supplied capacity is actually 26% smaller than the …
IF the battery power in volts matches the motor voltage rating (in my case 48V), and IF the battery ah is a tad less than the ah calculation of the motor (48V 1000watt...1000/48 = 20.83amp), how much can it overheat the motor (if any)? Assuming I use 4 x (in series) 12V 16ah LiFePO ) giving a power source of 48V 16ah and a calculated wattage of 768 (48 x 16)! Also …

If the battery has a maximum discharge rate of 10C, the maximum current is 20 amps. It''s good to keep in mind that a 10C discharge rate means a battery life of less than 1/10th of an hour, and with the loss of capacity that a high discharge …
Typically, starting uses less than three percent of the battery capacity. For this reason, automotive batteries are designed to deliver maximum current for a short period of time. They are sometimes referred to as "SLI batteries" for this reason, for starting, lighting and ignition. SLI batteries are not designed for deep discharging, and a full discharge can reduce the battery''s lifespan. As well as starting the engine, an SLI battery supplies the extra power necessary when the vehi…
