We have but two choices to power all electric vehicles: fuel cells or batteries. Both produce electricity to drive electric motors, eliminating the pollution and in efficiencies of the venerable internal combustion engine. Fuel cells derive their power from hydrogen stored on the vehicle, and batteries obtain their energy from the electrical grid.

The energy storage system is a very central component of the electric vehicle. The storage system needs to be cost-competitive, light, efficient, safe, and reliable, and to occupy little space and last for a long time. It should also be produced and disposed of in an environmentally friendly manner.

Flywheel energy storage (FES) works by accelerating a rotor () to a very high speed and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of ; adding energy to the system correspondingly results in an increase in the speed of th.

The best known and in widespread use in portable electronic devices and vehicles are lithium-ion and lead acid. Others solid battery types are nickel-cadmium and sodium-sulphur, while zinc-air is emerging. Another category is flow batteries with liquid electrolyte solutions, including vanadium redox and iron-chromium and zinc-bromine chemistries.

A bidirectional inverter delivers power from the utility during normal operations (solid line in the blue box) and charges your battery. When an outage occurs, a bidirectional inverter instantaneously switches to your backup battery to ensure continuous power for your devices (broken lines in the blue box).

Progress in home battery technology has enabled the storage of energy generated by your solar panels. When you pair your solar system with a home battery, you can store the excess generated electricity from your panels during the day for use at night. This means you can charge your EV using solar power, even after the sun has set.

The motor powers the electric tricycle, providing assistance to the rider. Motors typically range from 250W to 750W, depending on the model. The battery stores the energy needed to power the motor. Lithium-ion batteries are common due to their efficiency and long lifespan. Riders can expect a range of 20 to 50 miles on a single charge.

Energy Storage Equation The energy (E) stored in a capacitor is given by the following formula: E = ½ CV² Where: E represents the energy stored in the capacitor, measured in joules (J). C is the capacitance of the capacitor, measured in farads (F). V denotes the voltage applied across the capacitor, measured in volts (V).
