Lithium-ion batteries are very sensitive to temperature. At the same time they are equally bad tolerate extremely high and too low temperature, because when it gets very cold, the electrolyte liquid inside the battery becomes viscous and quickly loses its accumulating quality. This is especially critical for those electric vehicles that do not have their own battery temperature control system.
Also, unlike the engine of cars in which the engine produces its own heat, which “heats” the car, electric cars should take this heat somewhere else, as a rule, starting the heater, which is reflected in the battery life and reducing the power reserve. Continue reading
This week, some of the world’s largest automobile companies presented their flagship electric vehicles at the Shanghai motor show. Many of these electric cars will only be available in China, where there are government subsidies and policies in favor of electric cars. As the world’s largest car market and manufacturing center, China is becoming the center of electric car development.
On Tuesday, Audi introduced its electric sports crossover Q2L e-tron, which will be produced in the southern city of Foshan and is available only in the domestic market of China. The luxury German brand also launched an electric model for China, presenting it in San Francisco last year as the first production electric model. E-tron will also be produced in China starting from 2020. Continue reading
In Ukraine, the boom of artisanal manufacturers of charging equipment for electric vehicles. Most of the domestic charging equipment for electric vehicles is produced “in the kitchen”.
A little from the history of chargers and their cost
The charging station (portable or stationary), prior to the approval of the electric vehicle standards, was part of the inverter (so-called on-Board charger) of the electric vehicle. The decision to take part of the electronics outside the electric car was not accidental. The charging station is paired with the car’s Inverter at all stages of its charging. The quality of the charging process depends on the correctness of the charging station. Continue reading
