Particularly, described battery management system is also connected with for showing each cell dynamically and the display screen of battery capacity.Described battery management system is also connected to the Internet by the car network equipment, and battery pack information is uploaded to high in the clouds, and each cell is strip structure, makes it assemble rear just manpower transport.
Relay adopts MOSFET relay.
Implementation method of the present utility model, comprises step:
Cell each in battery pack is numbered by installation sequencing by a, battery management system, and is stored in corresponding control chip by numbering and positional information;
B, battery management system set the incipient discharge voltage of each cell by the sequencing that it is installed, and the cell incipient discharge voltage first installed is high, and the cell incipient discharge voltage of rear installation is low;
C, when motor need for the first time power supply time, the cell in this Battery pack group by install sequencing to motor, again need power supply time, power according to the sequence of incipient discharge voltage, until power bus is until bus voltage reaches stable.
In order to ensure that the electricity of each cell is consumed totally, and changing battery in time, ensureing the stability of whole system work.High will first the using of incipient discharge voltage exhausts, low the using after the meeting of incipient discharge voltage exhausts, in step c, all cells detect the voltage in power bus all in real time, the incipient discharge voltage of comparison self, the cell that incipient discharge voltage is high first discharges, corresponding relay closes, until bus voltage no longer reduces; When bus voltage raises, the cell that incipient discharge voltage is low is first stopped power supply, and corresponding relay disconnects, until bus voltage no longer raises.When again powering, the control chip Real-time Obtaining dump energy of each cell, and be sent to battery management system by optical communication interface, the dump energy of each cell sorts by battery management system, reset the incipient discharge voltage of each cell, setting principle is: the cell incipient discharge voltage that dump energy is many is low, and the cell incipient discharge voltage that dump energy is few is high.
In order to ensure the braking of electric motor car, the minimum power that battery pack provides when assembling must meet the maximum power of this electric motor car, in order to avoid electricity deficiency causes electric motor car to brake.
Further, control chip in described each cell calculates the electricity that self uses, and when making power consumption reach specified electric quantity (such as 1kwh), control relay disconnects, stop this cell to be motor and be set to power depletion state, and etc. to be replaced.Battery management system also obtains the power depletion state of each cell, and this power depletion state of output display and corresponding cell are numbered and position, and prompting user changes this cell.
In addition, described battery management system also calculates the dump energy of this battery pack and mileage of can walking, so that user grasps the situation of whole battery pack.The multidate information of described battery pack is also uploaded to high in the clouds, is convenient to unified management or inquiry.
Compared with prior art, the utility model has following beneficial effect:
(1) battery pack of the present utility model is applicable to the electric motor car of different capacity size, can increase or reduce power and the energy flexibly, and make electric motor car according to standard design, can need not consider battery, can not contain battery when therefore generating, thus commercial value can decline to a great extent.
(2) battery pack of the present utility model can unified management, and user by actual use amount, can rent battery, and safeguarded by the company of specialty, user need not worry reliability, and depot need not bear prolonged cell warranty responsibility.
(3) the utility model can make user according to the fast quickly replaceable battery of the charge condition of cell, need not wait charging for a long time, easy to maintenance, and ensures each battery consumption totally, avoids the wasting of resources.
