Hello, I am Matsuo, at MicroVehicle Lab.
We, Micro Vehicle Lab is providing the trial products such as experimental vehicles or lithium-ion batteries used in electric cars.
A micro vehicle stands for a vehicle which you can drive alone such as a wheelchair,..
electric motorcycle and this kind of vehicle.
We are assisting developing the batteries for cars, ships or robots.
The product in display this time is the protection circuit called battery management sysmtem that controls lithium-ion batteries.
We made the system with 80 volts 30Ah first.
The voltage of all cells are controlled by this protection circuit.
It monitors the upper and lower limits of the power voltage and detects the dispersion of the circuit to equalizing it.
This is for being able to be compatible with every new lithium-ion battery and ever-coming new positive-electrode materials.
We have developed this with the subsidy from Osaka Prefecture Government as EV Development Assistance Project.
We experimented the developed product, installing it in the car you have just looked.
With the result we have further developed the higher quality system this time.
This one can monitor and control the high-voltage circuit of 120 series.
This is the protection circuit as mentioned before.
Equalizing system and voltage monitor system is in this box.
This is the battery unit.
We would like you to use this for the smartgrit systems.
This product is compatible with them.
The special function of this is to eliminate the noise.
Under a high voltage condition, the noise against the cell and the noise from the inverter will be a problem.
We are trying to improve such points.
As mentioned before, this product’s advantage is that threshold level can be set to support any positive-electrode materials.
You will be able to see how much dispersion our product causes or in what kind of conditions it makes dispersion by arbitrarily setting the threshold level and manually equalize the voltage .
And also you can see the range of the variation our battery has, and also check what condition makes the change in preventing variation occurrence, by equalizing manually.
This small protection circuit is made very compact and...
can be use with up to 24 series.
This is good for electric bikes or large robots and its power consumption is made as small as possible.
We also display this today, a quasi power generator
to be used for checking the function of the protection circuit by setting the voltage.
We, Micro Vehicle Lab, would like to contribute to developing batteries, vehicles and the development of smartgrit.
I hope you are interested in our products.
