By determining the optimal charging current for each stage, the fuzzy controller is used to determine the charging current by the change in temperature. To sum up, this algorithm is based on a micro-controller or a computer. [6] The charging speed is faster and charging efficiency is higher than those of the CC/CV.
The voltage of the power outlet is usually near 12 V DC, and may be elevated between 13.5 V to 15 V while the engine is running. On trucks , the voltage of the power outlet may be near 24 V DC. The 12 V power circuit is protected by a car fuse , often rated at 10 to 20 amperes, which provides 120 to 240 watts of power.
A shunt charge controller or shunt regulator diverts excess electricity to an auxiliary or "shunt" load, such as an electric water heater, when batteries are full. [7] Simple charge controllers stop charging a battery when they exceed a set high voltage level, and re-enable charging when battery voltage drops back below that level.
Pre-charge of the powerline voltages in a high voltage DC application is a preliminary mode which limits the inrush current during the power up procedure. A high-voltage system with a large capacitive load can be exposed to high electric current during initial turn-on.
If more current than expected goes through the circuit-breaker, the circuit breaker "opens" the circuit and stops all current. A fuse is a common type of circuit breaker that involves direct effect of Joule-overheating. A fuse is always placed in series with the path of current it will affect.
Electric fans may provide comfort, but when the temperature is in the high 90s, fans will not prevent heat-related illness. Taking a cool shower or bath or moving to an air-conditioned place is a ...
While the notion of shared off-board DC charging infrastructure, together with the charging system design for CHAdeMO came out of TEPCOs trials starting in 2006, the connector itself had been designed in 1993, and was specified by the 1993 Japan Electric Vehicle Standard (JEVS) G105-1993 from the JARI.
