This type of control signal 0 can be used to control the duty cycle of the pulse width modulated signal by the pulse width modulation signal generator. In an embodiment, the pulse width modulation can be placed in the adapter. By adjusting the Bayesian period of the pulse width modulation signal, the adapter's output power at the output terminal 34G is adjusted relative to the shore. In other words, different charging modes can be enabled by adjusting the two cycles of the tracker's pulse width modulation. For example, if the battery is enabled according to the power-standard constant current charging mode ((6), analog control signal coffee (4) the duty cycle of the whole pulse width modulation signal, and then the adapter 302 rotates a certain charging current 1〇. 0390-TW-CH Spec-i-Claim(fiIed-20090724).doc 10 201001873 • In an embodiment, the control signal 350 is - Zhao.

In addition, in one embodiment, a charge switch within the command conversion 430 and a discharge switch 432 f control the battery pack 3 〇 4 when the electrical switch is turned off, the battery is charged in the embodiment, when acting as a battery-pair-system read map is not = ^: In the embodiment, P The discharge switch 432 in the embodiment - in order to improve the battery cell stack 304 also includes a function for balancing the battery cell - -3, the balance circuit 428. If an imbalance is detected" ~ 310-3 Battery balancing battery, battery unit 31 in group 304〇J-31 The balancing circuit 428 can be set to be outside the monitoring circuit 424. In the implementation: the imbalance battery enable-overcurrent can also be set (bypass current, ^428 can be ο shown, when the switch When the 41U is turned on, the battery cell balancing circuit is enabled. When _ slave 2 is turned on, the _ ^ mail current can be =. When the open 3 is turned on, the power 2 is enabled. The switch 410_1- 410 3 can & - the current of the dish can be requested. Therefore, the battery balance electric command conversion command converter 426. Also controlled by the ▲ circuit 424 or the battery imbalance county includes the following, but not in the middle, when a battery unit The voltage is 1 泰 =, and again in the example. The preset value is AV, then the voltage difference between the electric and the I soap element exceeds one when a battery unit is in a state of contact. In the embodiment - ' exceeds, no critical In the case of double ^, this electric 0,90-TW-CH Spec+Claim(filed-20090724).d〇c 11 201001873 is in an unbalanced state. Also, in another embodiment, the rate of change (change in battery voltage) When the voltage of the element is set to the critical value of the rate of change of the electric enthalpy (dv/dt)th, the Aihua of 1 exceeds a pre-state. Further, in another implementation In the case of the battery unit ^; = the difference in the capacity of the unbalanced cell unit is more than 1 and the other arbitrary electric unit is in an unbalanced state. The value of Δ〇, the battery is advantageous in that, as described above, Unbalanced, can output - smaller charging current (lightweight current adapter 302 charging.

In the step deletion, the constant current charging mode CCn is enabled by the control signal 350. For example, when n is set to 0, the standard constant current charging mode CCfl Will be enabled. When η is i ^ dirty, a light constant current charging mode CCn (n = 1, 2, ..., max) will be caused Month b. Step 606 performs a protection check. For example, in one embodiment, the command converter 426 receives the monitoring signal from the monitoring circuit 424 to determine if an abnormality has occurred (eg, overvoltage, overcurrent, and over temperature). If any anomalies occur, the process 600 will proceed to step 636 to terminate the battery charge 0390-TW-CH Spec+Claim(filed-20090724).doc 16 201001873 43◦ to terminate the second 5. The command converter 426. The charging switch is turned off at step 608. If there is no abnormality, the process 600 will go to the unit up to two through the command converter 426 to charge the battery group 304. For example, (4) ^ Over voltage) 4 is greater than the first set (indicating the appearance of the image), the stroke 6 will go to step 614. In step 614, the number f =. Then the flow 6GQ goes to step 624 to check whether it can be enabled Constant voltage: two; standard constant voltage charging mode (5). If the battery unit will go to the step voltage (indicating that there is no power plant phenomenon), the process _ in the system performs the imbalance check. In the embodiment When the difference between the voltages of the two battery cells is different - whether the preset voltage can enable the constant voltage charging mode (for example: charging type 4 (5). If the battery imbalance occurs in the inspection, the unbalanced electricity / material will cause The energy-overcurrent (this step is not shown in the process_) and the process 600 will go to step 615. In step 615, a timer is started. In step 616, if the timer =, the process _ will turn Going to step 618, η is added to 624, and it is checked to step 624 to check if a constant voltage charging mode (e.g., standard constant voltage charging mode CV) can be enabled. ). Next, in step 624, the battery average voltage of the battery pack is compared with the second preset ride through the command converter 426 to determine what is the constant voltage charging mode. If the battery average voltage is less than the second predetermined voltage, Flow_ will return to step 604 to begin a new charging cycle. Since in the previous cycle 0j90-TW-CH Spec+Claim(filed-20090724).doc 17 201001873, if an overvoltage phenomenon is detected in step 608, step 614 causes 1 to be incremented; if it is detected in step 610+ Unbalance, step ·6ΐ8 makes η add '1. Therefore, in this new cycle (current cycle), the charging current is adjusted from the first-level of the upper-period to the second level that is smaller than the _th level. The above steps _•step 6G4 and the following step_row are described in detail, and will not be repeatedly described herein for the sake of brevity.
