Electric cars perform less well in cold weather. Lower ambient temperatures affect an EV’s range, but also how quickly the battery charges and how effective its regenerative braking system works ...
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.
In practical use, charging speed is more relevant than battery capacity (see rechaging section). Typical EV batteries in passenger cars have a weight of 300 to 1,000 kg (660 to 2,200 lb) [88] resulting in ranges from 150 to 500 km (90 to 310 miles), depending on temperature, driving style and car type.
The cut-off voltage is different from one battery to the other and it is highly dependent on the type of battery and the kind of service in which the battery is used. When testing the capacity of a NiMH or NiCd battery a cut-off voltage of 1.0 V per cell is normally used, whereas 0.9 V is normally used as the cut-off voltage of an alkaline cell ...
Constant voltage charging is a widely used charging method involving constant voltage between the battery poles. The starter battery uses constant voltage charging when the vehicle is running. If the specified voltage constant value is appropriate, it can ensure that the battery is fully charged, while also minimizing gas and water loss.
During charging, the battery temperature typically stays low, around the same as the ambient temperature (the charging reaction absorbs energy), but as the battery nears full charge the temperature will rise to 45–50 °C. Some battery chargers detect this temperature increase to cut off charging and prevent over-charging.
A trickle charger is typically low-current (usually between 5–1,500 mA). They are generally used to charge small capacity batteries (2–30 Ah). They are also used to maintain larger capacity batteries (> 30 Ah) in cars and boats. In larger applications, the current of the battery charger is only sufficient to provide trickle current.

IUoU is a DIN-designation [1] (DIN 41773) for a lead-acid battery charging procedure that is also known as 3-stage charging, 3-phase charging, or 3-step charging.
