The more vigorous passion of manufacturers make hybrid electric cars and plug-ins bring new equipment. Something to have important role at this time is a tool to monitor or monitor the working conditions of the battery. Understandably, hybrid electric cars or plug-ins should use lithium-ion battery.
The company which it has already created the tool is Denso. Incidentally, this company is a major supplier of electrical and electronic components for Toyota, including the Prius. Denso makes the new equipment because Toyota wanted to get to market plug-in hybrid Prius.
Cheap Battery Voltage Monitoring "Lithium-Ion" of Denso
According to Denso, monitoring of lithium-ion battery is working with the new method. They use a simple voltage control circuits, so the production cost is cheaper compared to the voltage control method which it is widely used today, for example on a laptop computer and other hardware.
The unit monitors work by detecting the voltage, current, temperature and other parameters. In this way, high-voltage battery can still be used safely and efficiently. This is done because the lithium-ion batteries have higher energy density than nickel-metal batteries. Another factor is revealed that lithium-ion battery consists of many cells with the voltage up and down.
To control the voltage of conventional lithium-ion battery, which it is collected by analog voltage data from each cell is converted into digital form. After that, the data are processed by arithmetic circuit for detecting voltage of each cell. If the voltage is too high, then the excess is discarded.
According to Denso, the reliability of this new method with the conventional version is accountable. Those advantages, this device is simple because it does not require an analog-digital conversion circuits which it is capable of high or complex arithmetic circuits.
