A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
Solar cars are electric cars that use photovoltaic (PV) cells to convert sunlight into electrical power to charge the car's battery and to power the car's electric motors. Solar cars have been designed for solar car races and for public use. Solar vehicles must be light and efficient to get the best range from their limited captured power.
The power from the engine is split between the mechanical path and the generator. The battery also powers the motor, whose power is summed mechanically with the engine. If the battery state-of-charge is low, part of the power from the generator charges the battery.
The Dell-Winston School Solar Car Challenge is an annual solar-powered car race for high school students. The event attracts teams from around the world, but mostly from American high schools. The race was first held in 1995. Each event is the end product of a two-year education cycle launched by the Winston Solar Car Team.
There are three basic elements to the system - the power source, the battery, and the power management center. Sources for hybrid power include wind turbines, diesel engine generators, thermoelectric generators and solar PV systems. The battery allows autonomous operation by compensating for the difference between power production and use.

An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density.
The engine, fuel tank and gearbox are then removed and replaced with an electric motor, batteries and an inverter. [18] [19] [20] If the donor vehicle is a hybrid, the driveshaft can be retained also, as it has already been designed to work with electric car batteries and power delivery systems.
In 2014, researchers from the Ohio State University announced a hybrid solar cell-battery. Up to 20% of the energy produced by conventional solar cells is lost as it travels to and charges a battery. The hybrid stores nearly 100% of the energy produced. One version of the hybrid used a potassium-ion battery using potassium–air. It offered ...
