Background technology

Existing electric bicycle and power-assisted are substantially using monocell powering mode, use monomer Large Copacity Battery, such shortcoming is exactly that volume is big, battery weight is heavier;Monoblock battery when indivedual battery cores are damaged occur can not just make With maintenance, replacement cost are higher;No matter charge normal or change and be required for operating monoblock battery, very flexible.

The content of the invention

The main technical problem to be solved in the present invention is to provide a kind of power assist vehicle supplier of electricity of use multi-unit battery module Method, the reliability of electronic/electric booster bicycle battery.

In order to solve the above technical problems, the present invention provides a kind of power assist vehicle method of supplying power to of use multi-unit battery module:

Realized and broken the whole up into parts by the battery cell modules of standardization, an original monomer high capacity cell is divided into some Individual standard block;

Each unit is using cascade system so as to realize that each unit all can work independently, not interfere with each other;

Set power-supply management system realization to the detection of each unit operating mode and realize the automatic switchover of working cell.

During implementation, the capacity of each standard block is more than or equal to 3000 ampere-hours.

The quantity of the standard block is two or more.

The same time only one of which unit is in running order.

The power-supply management system includes:Respectively the battery detecting module of each standard block described in connecting detection, connect respectively Each standard block and couple output electricity to power unit variable connector, be connected in the battery detecting module and described Control module between variable connector, the control module is according to testing result of the battery detecting module to each standard block The variable connector is controlled to carry out the power switching of the power unit.

The detection parameter of the battery detecting module includes:Voltage, electric current and temperature.

The power unit includes a power assist vehicle motor.

The beneficial effects of the invention are as follows:A kind of power assist vehicle method of supplying power to of use multi-unit battery module, it passes through standard The battery cell modules of change, which are realized, to break the whole up into parts, and an original monomer high capacity cell is divided into several standard blocks; Each unit is using cascade system so as to realize that each unit all can work independently, not interfere with each other;Power-supply management system realization pair is set The detection of each unit operating mode and the automatic switchover for realizing working cell;By the present invention in that substitution of being powered with multi-unit battery module Traditional monocell is powered, so as to reduce battery maintenance cost, improve battery maintenance flexibility.

Embodiment

The present invention is described in further detail below by embodiment combination accompanying drawing.

A kind of power assist vehicle method of supplying power to of use multi-unit battery module, its concrete scheme is:

1st, realized and broken the whole up into parts by the battery cell modules of standardization, if an original monomer high capacity cell is divided into Dry capacity and size all moderate standard blocks.

2nd, each unit uses cascade system to realize that each unit all can work independently, not interfere with each other.

3rd, power-supply management system realizes the detection to each unit operating mode and realizes working cell(Battery working cell)From Dynamic switching.

During implementation, the capacity of each standard block is more than or equal to 3000 ampere-hours, to ensure suitable battery mark Quasi- unit volume and capacity.One vehicle can fill multiple batteries.

During implementation, the quantity of the standard block is two or more.Such case could realize switching, certainly, Work can also be realized using a standard block, but handoff functionality fails to play.

As shown in figure 1, each unit module uses cascade system, same time only one of which unit is in running order.Electricity Management system by measuring the operating mode of each unit in real time(Voltage or dump energy)Automatic switchover working cell.

Fig. 2 is hardware principle block diagram, please be described in detail:

Specific electric power detection module is made up of ADC and sample circuit, and sample circuit couples each standard block(Correspond connection), Control module is MCU, and each ADC, which is attached in MCU, variable connector, includes multiple independent SW.

Fig. 3 is program flow diagram, please be described in detail:

An embodiment of the present invention, degree flow is:

System initialization;

All switches are closed, working cell handoff threshold voltage is set, module group unit number is set, initialization unit is set;

Work as module group unit(Standard block)Number carries out short of electricity alarm less than preset value;

When module group unit reaches preset value, switch and detection unit voltage are opened;

When voltage reaches threshold voltage, then keep powering and continuing detection;

When voltage is less than threshold voltage, the standard block of control switching power supply.

Above content is to combine specific embodiment further description made for the present invention, it is impossible to assert this hair Bright specific implementation is confined to these explanations.For general technical staff of the technical field of the invention, do not taking off On the premise of from present inventive concept, some simple deduction or replace can also be made, the protection of the present invention should be all considered as belonging to Scope.
