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.
A crankcase ventilation system (CVS) removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold). The unwanted gases, called "blow-by", are gases from the combustion chamber which have leaked past the piston rings. Early ...
An exhaust heat recovery system turns waste heat energy in exhaust gases into electric energy for batteries or mechanical energy reintroduced on the crankshaft. The technology is of increasing interest as car and heavy-duty vehicle manufacturers continue to increase efficiency, saving fuel and reducing emissions.
Car lead–acid battery after explosion showing brittle fracture in casing ends. Excessive charging causes electrolysis, emitting hydrogen and oxygen in a process known as gassing. Wet cells have open vents to release any gas produced, and VRLA batteries rely on valves fitted to each cell.
Battery technology is non-transparent and lacks standards. Because battery development is the core part of EV, it is difficult for the manufacturer to label the exact chemistry of cathode, anode and electrolytes on the pack. In addition, the capacity and the design of the cells and packs changes on a yearly basis.
The English architect Sir Christopher Wren applied an early ventilation system in the Houses of Parliament that used bellows to circulate air. Wren's design was the catalyst for much later improvement and innovation. The first rotary fan used in Europe was for mine ventilation during the 16th century, as illustrated by Georg Agricola (1494 ...

When the car is on fast (DC) charge, the air conditioning system is automatically started and refrigerated air is blown through the battery pack for cooling purposes. There is a diverter flap in the ventilation system for this. From depletion, the battery may be charged to 80% full in 30 minutes using this socket.
