About Battery Capacity
Today I watched about electric plane on TED movie
Recently electric power has attracted attention. Because our society must care about our environment like carbon dioxide , noisy and earth resources.
Battery power give us to decrease carbon dioxide, and subside noisy and save earth resources because we replaces gasoline-power with electric power.
However we should be careful about battery.
These days battery capacity is increasing rapidly to use cars or tool for a long time as possible. However high capacity battery has high energy .
In other words, the higher battery capacity is , the more we are exposed to risk.
For example, If we drive electric cars which have high capacities and we encounter traffic accident, these cause big explosion and we may be badly injured .
This accident possibility is high.
So we should use battery with correct way and be careful to use battery.
Moreover, companies which make products with using batteries should attach safety construction and safety circuit to their product.
In summary , we should be careful for battery and we use it with correct way.
