The utlity model has following technical characterstic:
1), will discharge and recharge the close storage battery combo of performance graph, to connect again then, at last with the batteries parallel connection of connecting, and make each loop break-make in parallel controlled, by analysis to the signals such as voltage, electric current and temperature of each loop battery pack of parallel connection and every cell, in time cut off the loop of breaking down, the effective like this behindhand battery of having avoided " is led astray " other batteries.
2), increased external bank of super capacitors in the device.The capacitor group can be when service brake; effectively braking energy is stored; the voltage at its two ends finally can be identical with the voltage at battery pack two ends; in addition when brake hard; can prevent effectively that bigger current reflux is to battery pack; be unlikely to make the battery pack two ends to be subjected to big electric current, high-tension impact, protect battery pack effectively.But but the transient voltage electric current is when big,, except part energy reclaims by bank of super capacitors, also can on RB, consume by the conducting of control VB pipe, reach the purpose of protection battery pack.Simultaneously, can also provide energy supplement when starting, effectively avoid the super-large current discharge of battery pack moment, can alleviate influenced the battery pack life-span.
3), Bing Lian each series battery can effectively be controlled.By Controlled CPU to the battery pack that collects and the analysis of every signal such as monomer battery voltage, electric current and temperature, the battery pack that breaks down is cut off this branch road by the relay on each parallel branch timely, though reduced the electric current of total loop like this, reduce the part actuating force, but can guarantee the cruising of electric motor car.
4) it is controlled that, this device also is provided with the charger charging.By to CPU to each the loop battery pack that collects and the analysis of every signal such as monomer battery voltage, electric current and temperature, to the battery pack loop block system relay that has been full of, stop charging, avoid overcharging, owe to fill.And when starting working, charger cuts off the switch on the major loop automatically.
In the utility model Controlled CPU by the data analysis that collects is handled reached simultaneously that the charger charging is controlled, each battery-powered loop is controlled, main power circuit is controlled and the frequency converter management controlled etc., realized that really cpu data shares.
By said structure as can be seen, the utility model mainly comprises each loop series connection batteries, bank of super capacitors, frequency converter, Controlled CPU, charger, input signal, output signal and ac three-phase asynchronous motor etc. in parallel.During work, the signal of the voltage of battery, electric current, temperature acquisition, by the CAN bus, send into Controlled CPU and carry out Treatment Analysis, thereby the break-make of control each branch road in parallel, Controlled CPU is by the distributor circuit of input signal (comprise speed governing, rotating, crawl, acceleration, warning, suddenly stop and brake) control pwm signal, to the base drive of carrying out of inverter circuit, to reach the purpose of frequency control.Also be provided with memory in the system, when a certain parallel branch of battery pack breaks down, can when battery maintenance,, the difficulty of maintenance reduced greatly numbering, failure cause, abort situation record and the preservation of fault fault message output.System comprises that also panel shows, can show voltage, electric current, temperature, rotating speed and the output voltage etc. of battery pack.And alarm signal, running status, frequency signal can be exported timely.
When starting, many group batteries in parallel connection are worked simultaneously, strengthen actuating force, when falling the electric current in circuit, occurs, illustrated that battery breaks down, automatically cut off this group faulty circuit by controllable relays, other each Battery pack operate as normal that does as usual if two groups all break down, is cut off two-way automatically, each Battery pack operate as normal in addition, system operate as normal that does as usual.
The battery pack group effect is low, the parallel branch break-make is controlled, can effectively utilize braking energy, control is convenient, cpu data is shared, effectively increase the continuation of the journey mileage, with car load combination flexibly, single motor can be simplified the control system of car load and cost, reliability height.
