The unit of measurement used to indicate the capacity (the maximum charge) a battery can hold (e.g., 200 AH).
Battery balancing maintains the same voltage level across each battery cell, helping ensure they operate efficiently and enjoy a longer life cycle.
A lithium-ion battery comes in different shapes and sizes – cylindrical cells, pouch cells, and prismatic cells.
It’s a game of give and take – theoretically, some electric vehicles can store and return excess energy to the power grid when required, ensuring it doesn’t go to waste.
Depth of Discharge (DoD)
Depth of Discharge is a measurement of how much a battery is emptied compared to its total compacity. The deeper its discharge, the higher its range, but the shorter its life expectancy.
Electronic Control Device (ECD)
A component found in hybrid engines that connects the electric motor and the IC engine. It automatically switches to the optimum drive, depending on which is the most efficient at that time. Electronic power flow management ensures that the vehicle runs efficiently.
The amount of energy that can be stored per unit mass or volume of a battery. It is expressed in kilojoules (kJ) or kilowatt-hours (kWh).
The inverter connects the battery with the electric motor. The power electronics convert the DC voltage of the battery into high-frequency AC voltage, which forms the electromagnetic field for power generation in the electric motor.
A state-of-the-art energy source for electric vehicles. It converts electrical energy into chemical energy, which it stores until reconverting and releasing it as electrical energy when necessary.
The maximum possible output that an electric motor can achieve. It is comparable with the rated output of a combustion engine.
Permanent magnet synchronous machine (PMSM)
Just as combustion engines are separated by their use of petrol and diesel, electric motors are separated by the types of magnets they use. PMSM engines use permanent magnets, while electrically excited synchronous machine (ESM) engines use electromagnets. PMSM engines are far more common in Europe than the alternative.
Power availability display
A display in the instrument panel of electric vehicles that shows both the level of power being drawn from the drive system and the power recovered while braking and coasting. It replaces the tachometer found in vehicles with a combustion engine.
This defines how large and heavy a battery must be for a specified power level. The power density is determined by the materials used.
State of Charge (SOC)
Shows the remaining percentage of battery charge on the display of electric vehicles. It replaces the fuel display seen in vehicles with a combustion engine.
