Description
Technical field
The present invention relates to lithium ion battery, relate to specifically a kind of new type lithium ion battery group with protective device.
Background technology
With lead-acid battery, Ni-MH battery is compared, it is high that lithium ion battery has operating voltage, specific energy is high, have extended cycle life and to features such as environment are good, therefore the power resources as electric bicycle or battery-operated motor cycle have been applied widely, but because lithium ion battery adopts organic electrolyte, electrolyte lightning and boiling point are all very low, easily decompose at a lower temperature, produce gas, inner pressure of battery sharply rises and causes battery explosion, seek in serious potential safety hazard, now battery is through after repeatedly circulation and heavy-current discharge, be easy to cause the housing of lithium ion battery case to expand, also be certain hidden danger to the safety of battery.
Summary of the invention
In order to address the above problem, the invention provides a kind of lithium ion battery that can detect lithium ion battery temperature and voltage, this battery can detect the swelling of lithium ion battery, avoids causing danger.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of new type lithium ion battery group with protective device; comprise lithium ion battery group; a side in lithium ion battery group is provided with temperature-detecting device; opposite side in lithium ion battery group is provided with voltage check device, on the housing of lithium ion battery group, displacement sensor is installed.
Further improvement of the present invention is: temperature-detecting device is connected with a temperature indicator, and voltage check device connects a battery allowance display instrument.
Further improvement of the present invention is: on battery allowance display instrument, be also provided with warning device.
Further improvement of the present invention is: warning device is voice message or jingle bell.
The invention has the beneficial effects as follows: the present invention has connected temperature indicator and battery allowance display instrument in the outside of lithium ion battery group, can check simply and easily temperature and the battery allowance of lithium ion battery, user can check the temperature of battery in time, avoid causing danger, after repeatedly circulation and large electric current facilitate, the gas of battery container inside increases, cause the expansion of lithium ion battery case, the displacement sensor being placed on lithium ion battery case senses when this moves, notify user by the mode of reporting to the police, avoid the danger of blasting, lithium ion battery travels and is easy to make short circuit between electrodes under under-voltage state, and the situation that the warning device that battery allowance display instrument connects can be reminded user's cell voltage timely, extend the useful life of lithium ion battery.
The present invention is simple in structure, relates to rationally, easy to operate, avoids causing danger, and extends the useful life of lithium ion battery.
