Comparison AIMA Mine Plus vs AIMA Big Bull

The range of a vehicle is the distance it can travel on a single battery charge.

Note that the range usually indicates the value for perfect operating conditions: driving at optimal speed with a small load, flat road, no ups and downs, etc. The actual range may differ from the claimed one, sometimes quite noticeably. In addition, to improve range, manufacturers can deliberately use low-power motors that consume little energy.

The motor power of a vehicle, in horsepower.

In general, the power of electric motors is indicated in watts. However, in electric transport, this designation is also often indicated. This is done for the convenience of comparison with internal combustion engines: for internal combustion engines, especially in vehicles, horsepower is traditionally used, and it is more convenient for some users to evaluate the power of motors by this designation. At the same time, if the need arises, some units are easily converted to others: 1 hp. ≈ 735 W.

For the power value in general, see the relevant paragraph below.

The motor power of a vehicle, in kilowatts. In addition to them, horsepower is also used (for more details, see above).

Let us clarify that in this case, we are talking about maximum power; the actual power can be adjusted while driving with the help of the accelerator. And in some models, it may even be possible to set a limit on the maximum power.

A more powerful motor allows you to carry more weight, reach higher speeds and/or have more torque. However, the energy consumption from the battery will also be high, and the battery life, with the same battery capacity, will be correspondingly less than when using a less powerful motor. Also note that in many countries, motor power is a criterion for classifying an electric vehicle as one or another variety. For example, according to this criterion, motorcycles and scooters can be formally separated, requiring different driving licences.

The highest speed that a vehicle can reach.

When choosing according to this parameter, it is worth considering that in dense city traffic, it is rarely possible to accelerate faster than 40 km/h; so if the vehicle is bought mainly for a comfortable ride through traffic jams, then there is no need to look for a high-speed model. In addition, for the same motor power, low speed means more torque, which makes it easier to climb hills.

The maximum incline that the vehicle can overcome.

Most vehicles, even the most inexpensive ones, can cope with angles of 10 – 12 ° without problems. So you should pay special attention to this parameter only if you have to deal with very steep slopes.

It is also worth mentioning that on road signs the angle of elevation is usually indicated not in degrees, but as a percentage. This means that to evaluate the capabilities of a particular unit, it may be necessary to convert degrees to percentages or vice versa. For this, there are special tables and calculators.

— Lead-acid. The most popular type today. Their design is based on a combination of electrodes made of lead compounds and an electrolyte, the role of which is played by sulfuric acid diluted with water. It is the classic type of batteries that use a conventional liquid electrolyte. Their widespread use is due to their simple design and low cost, combined with good capacity and starting currents characteristic of all lead-acid batteries, as well as resistance to low temperatures (compared to other types of batteries).

— Lithium-ion (Li-Ion). Lithium-ion technology was originally used in batteries for portable gadgets such as mobile phones, but such batteries are being used more and more recently in vehicles. Among the advantages of such batteries, one can note smaller dimensions and weight, the ability to deliver high starting currents and the ability to be charged with high currents (the latter significantly reduces the charging time), as well as numerous charge-discharge cycles. In addition, such batteries contain a minimum of harmful substances, do not use acids and heavy metals, and some models are even directly positioned as absolutely harmless to the environment. The main disadvantage of lithium-ion models is the high price.

— Gel. A type of lead-acid battery in which the electrolyte is not liquid, but condensed to a gel state. This design prov...ides several advantages compared to the classic version (see above): more charge-discharge cycles (which means longer service life); minimum leakage of electrolyte and associated gases; no need for maintenance; resistance to deep discharges and temperature fluctuations, etc. On the other hand, such batteries cost significantly more.

The capacity of the battery installed in the vehicle, in ampere-hours.

Theoretically, the battery life of the vehicle directly depends on this parameter: a more capacious battery can supply the electric motor longer. However, the actual amount of stored energy depends not only on the capacity in amp-hours but also on the nominal voltage of the battery. A more correct unit in this sense is watt-hours, taking into account the difference in nominal voltages; see "Battery capacity" below for details on this designation. Additionally, the operating time on a charge will depend not only on the characteristics of the battery but also on the power consumption of the vehicle itself — and it is determined by the motor power and several other parameters.

The capacity of the battery that is installed in the vehicle, in watt-hours.

To correctly compare batteries of different capacities and voltages, the designation in watt-hours is used. In addition, such a designation is convenient for estimating the operating time on a charge: for example, with an engine power of 2 kW, a battery of 3000 Wh is enough to power it at maximum power for 3000/2000 = 1.5 hours.

As for the capacity of the battery as a whole, theoretically, the battery life of the vehicle directly depends on it. However, the operating time will also be determined by the power consumption of the unit itself — and it is influenced by both the mentioned motor power and several other parameters.

The presence of a removable battery allows you to replace it with a more capacious one. This option also allows you to change one for another on the road, thereby increasing the range.
