Range anxiety is the driver's fear that a vehicle has insufficient energy storage (fuel and/or battery capacity) to cover the road distance needed to reach its intended destination, and would thus strand the vehicle's occupants mid-way. The term, which is now primarily used in reference to battery electric vehicles (BEVs), is considered to be one of the major psychological barriers to large-scale public adoption of electric vehicles.

By taking the input from the throttle, input from the motor sensors, and the power supply from the battery, the controller makes sure the BLDC motor delivers the exact speed and torque required to the user as per the throttle input, the controller also takes the input from hall sensors in the motor to complete a feedback circuit for ensuring in the smooth running of the motor,

To provide safety with the braking system, the power flow to the motor will cut down as soon as the brake is engaged.

Battery management system (BMS) is technology dedicated to the oversight of a battery pack, which is an assembly of battery cells, electrically organized in a row x column matrix configuration to enable the delivery of a targeted range of voltage and current for a duration of time against expected load scenarios. The oversight that a BMS provides usually includes:

👉Monitoring the battery
👉Providing battery protection
👉Estimating the battery’s operational state
👉Continually optimizing battery performance
👉Reporting operational status to external devices

Here, the term “battery” implies the entire pack; however, the monitoring and control functions are specifically applied to individual cells, or groups of cells called modules in the overall battery pack assembly. Lithium-ion rechargeable cells have the highest energy density and are the standard choice for battery packs for many consumer products, from laptops to electric vehicles. While they perform superbly, they can be rather unforgiving if operated outside a generally tight safe operating area (SOA), with outcomes ranging from compromising the battery performance to outright dangerous consequences. The BMS certainly has a challenging job description, and its overall complexity and oversight outreach may span many disciplines such as electrical, digital, control, thermal, and hydraulic.

A prismatic cell is a cell whose chemistry is enclosed in a rigid casing. Its rectangular shape allows efficiently stacking multiple units in a battery module. There are two types of prismatic cells: the electrode sheets inside the casing (anode, separator, cathode) are either stacked or rolled and flattened.

The EV industry evolves quickly, and it’s uncertain whether prismatic cells or cylindrical cells will prevail. At the moment, cylindrical cells are more widespread in the EV industry, but there are reasons to think prismatic cells will gain in popularity.

First, prismatic cells offer an opportunity to drive down costs by diminishing the number of manufacturing steps. Their format makes it possible to manufacture larger cells, which reduces the number of electrical connections that need to be cleaned and welded.

Prismatic batteries are also the ideal format for the lithium-iron phosphate (LFP) chemistry, a mix of materials that are cheaper and more accessible. Unlike other chemistries, LFP batteries use resources that are everywhere on the planet. They do not require rare and expensive materials like nickel and cobalt that drive the cost of other cell types upward.

There are strong signals that LFP prismatic cells are emerging. In Asia, EV manufacturers already use LiFePO4 batteries, a type of LFP battery in the prismatic format. Tesla also stated that it has begun using prismatic batteries manufactured in China for the standard range versions of its cars.

The LFP chemistry has important downsides, however. For one, it contains less energy than other chemistries currently in use and, as such, can’t be used for high-performance vehicles like Formula 1 electric cars. In addition, battery management systems (BMS) have a hard time predicting the battery’s charge level.

When it comes to battery pack production demand, energy storage systems (ESS) are just as important as electric vehicles. ESSs are already using prismatic cells and it is very likely that they will keep using them. Prismatic cells have a longer cycle life, are less dangerous, and come at a low cost compared to cylindrical cells.

The lithium iron phosphate battery (LiFePO
4 battery) or LFP battery (lithium ferrophosphate) is a type of lithium-ion battery using lithium iron phosphate (LiFePO4) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. The energy density of an LFP battery is lower than that of other common lithium ion battery types such as Nickel Manganese Cobalt (NMC) and Nickel Cobalt Aluminum (NCA), and also has a lower operating voltage; CATL's LFP batteries are currently at 125 watt hours (Wh) per kg, up to possibly 160 Wh/kg with improved packing technology, while BYD's LFP batteries are at 150 Wh/kg, compared to over 300 Wh/kg for the highest NMC batteries. Notably, the energy density of Panasonic’s “2170” batteries used in 2020 in Tesla’s Model 3 is around 260 Wh/kg, which is 70% of its "pure chemicals" value.

Because of its lower cost, high safety, low toxicity, long cycle life and other factors, LFP batteries are finding a number of roles in vehicle use, utility scale stationary applications, and backup power. LFP batteries are cobalt-free. As of Q1 2021, LFP type battery market share reached 24.1%,with Chinese manufacturers holding a near monopoly,and is expected to rise further to surpass NMC type batteries in 2028.

A lithium-ion (Li-ion) battery
- one of the best choices for your electric vehicles -is an advanced battery technology that uses lithium ions as a key component of its electrochemistry. During a discharge cycle, lithium atoms in the anode are ionized and separated from their electrons. The lithium ions move from the anode and pass through the electrolyte until they reach the cathode, where they recombine with their electrons and electrically neutralize. The lithium ions are small enough to be able to move through a micro-permeable separator between the anode and cathode. In part because of lithium’s small size (third only to hydrogen and helium), Li-ion batteries are capable of having a very high voltage and charge storage per unit mass and unit volume.

Li-ion batteries can use a number of different materials as electrodes. The most common combination is that of lithium cobalt oxide (cathode) and graphite (anode), which is most commonly found in portable electronic devices such as cellphones and laptops. Other cathode materials include lithium manganese oxide (used in hybrid electric and electric automobiles) and lithium iron phosphate. Li-ion batteries typically use ether (a class of organic compounds) as an electrolyte.

An axial flux motor (also known as an axial gap motor, or pancake motor) is a geometry of electric motor construction where the gap between the rotor and stator, and therefore the direction of magnetic flux between the two, is aligned parallel with the axis of rotation, rather than radially as with the concentric cylindrical geometry of the more common radial gap motor.

Although this geometry has been used since the first electromagnetic motors were developed, its usage was rare until the widespread availability of strong permanent magnets and the development of brushless DC motors, which could better exploit this geometry's advantages.

Axial geometry can be applied to almost any operating principle (e.g. brushed DC, induction, stepper, reluctance) that can be used in a radial motor. Axial designs allow some topologies that would not be practical in a radial geometry. Even for the same operating principle, application and design considerations make one geometry more suitable than the other. Axial motors are typically shorter and wider than an equivalent radial motor.

In a direct drive hub motor, the axle that passes through the center of the motor is actually the axle of the motor itself, with the copper windings fixed to the axle. This whole axle assembly is called the “stator”. The magnets are mounted to the outer shell of the hub motor. When electricity is applied to the stator a magnetic field is induced that causes the magnets to move. This in turn makes the whole shell of the motor turn and propels the wheel forward.

A geared hub motor uses a system of gears, within the hub itself, that transfer the turning force of the motor through to the hub and the wheel. The central gear, fixed to the spinning motor, turns through a series of other gears (called epicyclic and annulus) onto the wheel hub.

The main point to get across is that the gearing inside the hub reduces the fast speed the motor turns at to enable the wheel to turn at a more suitable speed. Motors like to turn at a fast speed, much faster than your bike wheel turns, hence the need for gearing. Geared hub motors are the commonest and most budget form of hub motors.

The hub motor (also called wheel motor, wheel hub drive, wheel hub motor, or in-wheel motor) is characterized by the integration of power, transmission and braking devices into the wheel hub, thus greatly simplifying the mechanical part of electric vehicles. Hub motor is not a new thing, as early as 1900, already manufactured the front wheel equipped with hub motor electric vehicles, in the 1970s, hub motor technology in the field of mining transport vehicles and other applications.

Hub motors have an inherent efficiency advantage because there is no meaningful intermediary between the motor and the road. The mechanical power from the motor goes directly into the tire-road interface, and there are no real efficiency losses there.
