1.3贮存蓄电池在安装前可在0~38℃的环境温度下存放，存放期一般为6个月（半年），存放期为6个月的电池应进行补充电。

1.4选型选择蓄电池时应根据使用频次放电电流放电时间等情况，容量应尽量选大一些，以避免过放电和超大电流放电时对蓄电池造成损害，蓄电池放电时，放电电流一般控制在0.1C10A以下。

1.5蓄电池使用环境及注意事项1.5.1蓄电池使用环境应干燥清洁通风；不能受到大量辐射、放射；不能受到有机溶剂及其气体的腐蚀；避免阳光直射，温度不超过38℃。

1.5.2取暖器或空调通风孔不应直接对着蓄电池，应尽量使蓄电池组各部位温差不超过3 ℃，建议定期采用红外线测温仪来检测蓄电池各部位的温度。

1.5.3蓄电池可采用制造厂提供的电池柜或电池架安装，也可采取地面安装，蓄电池安装在楼上时应向土建部门提出负荷要求，抗震烈度为7级以上的地区，应设计防震支架并采用地脚螺栓固定。

1.5.4蓄电池组安装时应尽量靠近负载，选用的电缆铜排连接线要合适（选择线径可以提档使用切不可降档对付），以免增加线路压降，多路并联使用时，应尽量使线路压降大致相同，且每组电池配备熔断保护器。

1.5.5电池组电压较高，存在电击危险，在装卸导电电缆（铜排连接线）时，应使用绝缘防护工具，如戴防护手套等，不要造成电池短路打火。

8205a中文资料锂电池保护板根据使用的不同IC和电压具有不同的电路和参数。

常用的保护IC是8261，DW01 +，CS213，GEM5018等。

其中，精工的8261系列具有更好的精度，当然价格也更昂贵。

后者全部在台湾制造。

国内二级市场主要使用DW01 +和CS213。

以下是带有MOS管8205A（8pin）的DW01 +的说明：锂电池保护板的正常工作流程为：当电池电压在2.5V至4.3V之间时，DW01的第一引脚和第三引脚均输出高电平（等于电源电压），第二引脚电压为0V。

此时，DW01的引脚1和3的电压将分别施加到8205A的引脚5和4。

由于8205A中的两个电子开关的G 极连接到DW01的电压，因此它们处于导通状态。

两个电子开关均处于打开状态。

此时，电池单体的负极直接连接至保护板的P-端子，并且保护板具有电压输出。

2.保护板过放电保护控制原理：当电池通过外部负载放电时，电池电压将缓慢降低，与此同时，DW01将通过R1电阻实时监控电池电压。

当电池电压降至约2.3V时，DW01将认为电池电压处于过放电电压状态，引脚1的输出电压立即断开，从而引脚1的电压变为0V，并且开关由于引脚5上没有电压，因此8205A中的电子管关闭。

此时，电池单元的B-和保护板的P-处于断开状态。

即，电池单元的放电电路被切断，并且电池单元将停止放电。

保护板处于过放电状态，并且已经维护。

保护板的P 和P-具有间接充电电压后，DW01通过B-检测到充电电压后，将立即停止过放电状态，并再次在引脚1上输出高电压以开启过放电控制8205A中的电子管。

也就是说，电池单元的B-和保护板的P-被重新连接，并且电池由充电器直接充电。

3.保护板过充保护控制原理：当电池由充电器正常充电时，随着充电时间的增加，电池的电压将越来越高。

当电池电压升至4.4V时，DW01将认为电池电压处于过充电电压状态。

然后立即断开引脚3的输出电压，以使引脚3的电压变为0V，并且由于引脚4上没有电压，因此8205A中的开关管被闭合。

Figure7and Figure8for a typical charge profile.Figure9.Typical Charging ProfileThe bq241xx provides an integrated fixed1MHz frequency voltage-mode controller with Feed-Forward function to regulate charge current or voltage.This type of controller is used to help improve line transient response, thereby simplifying the compensation network used for both continuous and discontinuous current conduction operation.The voltage and current loops are internally compensated using a Type-III compensation scheme that provides enough phase boost for stable operation,allowing the use of small ceramic capacitors with very low ESR.There is a0.5V offset on the bottom of the PWM ramp to allow the device to operate between0%to100% duty cycle.The internal PWM gate drive can directly control the internal PMOS and NMOS power MOSFETs.The high-side gate voltage swings from V CC(when off),to V CC-6(when on and V CC is greater than6V)to help reduce the conduction losses of the converter by enhancing the gate an extra volt beyond the standard5V.The low-side gate voltage swings from6V,to turn on the NMOS,down to PGND to turn it off.The bq241xx has two back to back common-drain P-MOSFETs on the high side.An input P-MOSFET prevents battery discharge when IN is lower than BAT.The second P-MOSFET behaves as the switching control FET,eliminating the need of a bootstrap capacitor.Cycle-by-cycle current limit is sensed through the internal high-side sense FET.The threshold is set to a nominal 3.6A peak current.The low-side FET also has a current limit that decides if the PWM Controller will operate in synchronous or non-synchronous mode.This threshold is set to100mA and it turns off the low-side NMOS before the current reverses,preventing the battery from discharging.Synchronous operation is used when the current of the low-side FET is greater than100mA to minimize power losses.Temperature QualificationRT1+VO(VTSB)VLTF*11RT2)1RTHCOLDRT2+V O(VTSB) RTH

2007The bqSWITCHER continuously monitors battery temperature by measuring the voltage between the TS pin and VSS pin.A negative temperature coefficient thermistor (NTC)and an external voltage divider typically develop this voltage.The bqSWITCHER compares this voltage against its internal thresholds to determine if charging is allowed.To initiate a charge cycle,the battery temperature must be within the V (LTF)-to-V (HTF)thresholds.If battery temperature is outside of this range,the bqSWITCHER suspends charge and waits until the battery temperature is within the V (LTF)-to-V (HTF)range.During the charge cycle (both precharge and fast charge),the battery temperature must be within the V (LTF)-to-V (TCO)thresholds.If battery temperature is outside of this range,the bqSWITCHER suspends charge and waits until the battery temperature is within the V (LTF)-to-V (HTF)range.The bqSWITCHER suspends charge by turning off the PWM and holding the timer value (i.e.,timers are not reset during a suspend condition).Note that the bias for the external resistor divider is provided from the VTSB output.Applying a constant voltage between the V (LTF)-to-V (HTF)thresholds to the TS pin disables the temperature-sensing feature.Figure 10.TS Pin ThresholdsOn power up,if the battery voltage is below the V LOWV threshold,the bqSWITCHER applies a precharge current,I PRECHG ,to the battery.This feature revives deeply discharged cells.The bqSWITCHER activates a safety timer,t PRECHG ,during the conditioning phase.If the V LOWV threshold is not reached within the timer period,the bqSWITCHER turns off the charger and enunciates FAULT on the STATx pins.In the case of a FAULT condition,the bqSWITCHER reduces the current to I DETECT .I DETECT is used to detect a battery replacement condition.Fault condition is cleared by POR or battery replacement.I O(PRECHG)+K (ISET2) V (ISET2)ǒR (ISET2) R (SNS)Ǔ(2)Battery Charge CurrentR (SNS)+V IREGI OCHARGE (3)R ISET1+K ISET1 V

2004–REVISED NOVEMBER 2007The magnitude of the precharge current,I O(PRECHG),is determined by the value of programming resistor,R (ISET2),connected to the ISET2pin.whereR SNS is the external current-sense resistor V (ISET2)is the output voltage of the ISET2pin K (ISET2)is the V/A gain factorV (ISET2)and K (ISET2)are specified in the Electrical Characteristics table.The battery charge current,I O(CHARGE),is established by setting the external sense resistor,R (SNS),and the resistor,R (ISET1),connected to the ISET1pin.In order to set the current,first choose R (SNS)based on the regulation threshold V IREG across this resistor.The best accuracy is achieved when the V IREG is between 100mV and 200mV.If the results is not a standard sense resistor value,choose the next larger ing the selected standardvalue,solve for V IREG .Once the sense resistor is selected,the ISET1resistor can be calculated using the following equation:The voltage regulation feedback occurs through the BAT pin.This input is tied directly to the positive side of the battery pack.The bqSWITCHER monitors the battery-pack voltage between the BAT and VSS pins.The bqSWITCHER is offered in a fixed single-cell voltage version (4.2V)and as a one-cell or two-cell version selected by the CELLS input.A low or floating input on the CELLS selects single-cell mode (4.2V)while a high-input through a resistor selects two-cell mode (8.4V).The bqSWITCHER monitors the charging current during the voltage regulation phase.Once the termination threshold,I TERM ,is detected,the bqSWITCHER terminates charge.The termination current level is selected by the value of programming resistor,R (ISET2),connected to the ISET2pin.whereR (SNS)is the external current-sense resistor V TERM is the output of the ISET2pin K (ISET2)is the A/V gain factorV TERM and K (ISET2)are specified in the Electrical Characteristics tableAs a safety backup,the bqSWITCHER also provides a programmable charge timer.The charge time is programmed by the value of a capacitor connected between the TTC pin and GND by the following formula:Sleep ModeCharge Status OutputsPG OutputCE Input (Charge Enable)bq24113,bq24113A,bq24115SLUS606K–JUNE 2004–REVISED NOVEMBER 2007whereC (TTC)is the capacitor connected to the TTC pin K (TTC)is the multiplier A new charge cycle is initiated when one of the following conditions is detected:•The battery voltage falls below the V RCH threshold.•Power-on reset (POR),if battery voltage is below the V RCH threshold •CE toggle•TTC pin,described as follows.In order to disable the charge termination and safety timer,the user can pull the TTC input below the V TTC_EN threshold.Going above this threshold enables the termination and safety timer features and also resets the timer.Tying TTC high disables the safety timer only.The bqSWITCHER enters the low-power sleep mode if the VCC pin is removed from the circuit.This feature prevents draining the battery during the absence of VCC.The open-drain STAT1and STAT2outputs indicate various charger operations as shown in Table 1.These status pins can be used to drive LEDs or communicate to the host processor.Note that OFF indicates that the open-drain transistor is turned off.Table 1.Status Pins SummaryCharge StateSTAT1STAT2Charge-in-progress ON OFF Charge completeOFF ON Charge suspend,timer

low-level signal on this pin enables the charge and a high-level V CC signal disables the charge.A high-to-low transition on this pin also resets all timers and fault conditions.Note that the CE pin cannot be pulled up to VTSB voltage.This may create power-up issues.Timer Fault RecoveryOutput Overvoltage Protection (Applies To All Versions)Functional Description for System-Controlled Version

2004–REVISED NOVEMBER 2007As shown in FIGURE 10,bqSWITCHER provides a recovery method to deal with timer fault conditions.The following summarizes this method.Condition 1V I(BAT)above recharge threshold (V OREG -V RCH )and timeout fault occurs.Recovery method:bqSWITCHER waits for the battery voltage to fall below the recharge threshold.This could happen as a result of a load on the battery,self-discharge or battery removal.Once the battery falls below the recharge threshold,the bqSWITCHER clears the fault and enters the battery absent detection routine.A POR or CE toggle also clears the fault.Condition 2Charge voltage below recharge threshold (V OREG –V RCH )and timeout fault occursRecovery method:Under this scenario,the bqSWITCHER applies the I DETECT current.This small current is used to detect a battery removal condition and remains on as long as the battery voltage stays below the recharge threshold.If the battery voltage goes above the recharge threshold,then the bqSWITCHER disables the I DETECT current and executes the recovery method described in Condition 1.Once the battery falls below the recharge threshold,the bqSWITCHER clears the fault and enters the battery absent detection routine.A POR or CE toggle also clears the fault.The bqSWITCHER provides a built-in overvoltage protection to protect the device and other components against damages if the battery voltage gets too high,as when the battery is suddenly removed.When an overvoltage condition is detected,this feature turns off the PWM and STATx pins.The fault is cleared once V IBAT drops to the recharge threshold (V OREG –V RCH ).For applications requiring charge management under the host system control,the bqSWITCHER (bq2411x)offers a number of control functions.The following section describes these functions.A low-level signal on the CMODE pin forces the bqSWITCHER to charge at the precharge rate set on the ISET2pin.A high-level signal forces charge at fast-charge rate as set by the ISET1pin.If the battery reaches the voltage regulation level,V OREG ,the bqSWITCHER transitions to voltage regulation phase regardless of the status of the CMODE input.The charge timers and termination are disabled in the system-controlled versions of the bqSWITCHER.The host system can use the CE input to enable or disable charge.When an overvoltage condition is detected,the charger process stops,and all power FETs are turned off.The bqSWITCHER provides internal loop compensation.With this scheme,best stability occurs when LC resonant frequency,f o is approximately 16kHz (8kHz to 32kHz).Equation 7can be used to calculate the value of the output inductor and capacitor.Table 3provides a summary of typical component values for various charge rates.Table 3.Output Components

1.电池保护板的工作原理：锂电池保护板的电路和参数因IC和电压的不同而不同。

常用的保护芯片是8261，DW01 +，CS213，GEM5018等。

精工的8261系列具有更好的精度，当然也更昂贵。

后者来自台湾，国内二级市场主要使用DW01 +和CS213。

DW01 +使用MOS管8205A（8pin）给出以下说明：锂电池保护板的正常工作过程是：当电池电压在2.5V至4.3V之间时，DW01的第一和第三引脚输出高电平（等于电源电压），第二个引脚电压为0V。

此时，DW01的引脚1和引脚3的电压将分别施加到8205A的引脚5和引脚4上。

因为8205A中的两个电子开关的g极连接到DW01的电压，所以它们都处于导通状态，即两个电子开关都处于导通状态。

此时，电池单元的负极等效于与保护板的P-端子直接连通，并且保护板具有电压输出。

2.保护板的过放电保护控制原理：当电池通过外部负载放电时，电池的电压会逐渐降低，同时，电池的电压将通过R1电阻进行实时监控在DW01内部。

当电池电压降至约2.3V时，DW01会认为电池电压处于过放电电压状态，并立即断开第一引脚的输出电压，从而使第一引脚的电压变为0V，由于第5脚上没有电压，因此8205A中的开关管将闭合。

此时，电池芯的B-与保护板的P-断开。

即，当电池单元的放电电路被切断时，电池单元将停止放电。

保护板处于过放电状态，并一直保持。

在保护板的P-和P-间接施加了充电电压后，DW01在通过B-检测到充电电压后立即停止过放电，并再次在引脚1上输出高电压，从而打开了8205A中的过放电控制管。

即，电池芯的B-与保护板的P-重新连接，并且电池芯由充电器直接充电。

3.保护板过充保护控制原理：当充电器正常给电池充电时，随着充电时间的增加，电池单元的电压会越来越高。

当电池电压升至4.4V时，DW01会认为电池电压处于过充电电压状态，并立即断开第三个引脚的输出电压，从而使第三个引脚的电压变为0V，并且开关由于第四个引脚没有电压，因此8205A中的电子管关闭。
