[0061] 这种安装结构还有助于将充电电路58暴露于任何可能进入空腔30的外来物(如污物、沙尘、碎石、锯屑、金属屑、水、油、油脂等)的可能性降至最低。 [0061] This structure also helps install the charging circuit 58 may be exposed to any foreign matter into the cavity 30 (e.g., dirt, sand, gravel, sawdust, metal shavings, water, oil, grease, etc.) minimize the possibility. 依赖于外壳18的方向, 任何进入空腔30的外来物将会沿腔壁内或紧邻腔壁静止。 Depends on the direction of the housing 18, any foreign matter into the cavity 30 will be in close proximity to the lumen wall or cavity wall stationary. 因此,将充电电路悬挂在外壳18 的中间,任何外来物接触或静止充电电路58上的可能性都较小。 Therefore, the charging circuit 18 is suspended in the middle of the housing, the possibility of contact with any foreign object or a stationary charging circuit 58 are small.

[0062] 充电电路58可与电源(未示出)连接,如通过电源软线64与交流电源相连或与直流电源相连。 [0062] The charging circuit 58 may be connected to a power source (not shown), such as attached to or connected to the DC power supply through the power cord 64 of AC power. 电池槽70上的充电端子66将电池14与充电电路58连接。 Charging terminal 70 of the battery 66 on the battery 14 is connected to tank circuit 58 and the charging.

[0063] 如图12所示,充电器10为每个电池槽70采用了一个专用的充电电路58。 [0063] As shown in FIG 12, the battery charger 10 for each channel 70 uses a dedicated charging circuit 58. 采用这种结构,如果一个充电电路失效,其余的充电电路58仍可工作,充电器就不会完全失效。 With this configuration, if a failure of the charging circuit, the charging circuit 58 still remaining work, the charger will not fail completely. 每一个充电电路58都与授权于2001年4月24日的美国专利No. 6,222,343和提交于2000 年9月29日的美国专利申请No. 09/672,620,以及这里作为参考的授权于2002年9月24 日的美国专利No. 6,456,035。 Each charging circuit 58 are 6,222,343 filed on September 29, 2000 and authorized on April 24, 2001, US Patent No. US Patent Application No. 09 / 672,620, and incorporated by reference herein US patents on September 24, 2002 of No. 6,456,035.

[0064] 如图10-11所示,通气孔74位于第一外壳22的较低部分,通气孔78位于第二外壳26的较高部分。 [0064] As shown, the vent hole 74 located in the lower portion of the first housing 22, 10-11 vent holes 78 located on the upper portion of the second housing 26. 通气孔74,78将阶梯升高的通道82包括进空腔30中。 The vent holes 74, 78 of channel 82 includes a stepped raised into cavity 30. 每个通道82的结构中包括外缘84,可能实际上是平面的间隔段86,以及朝向间隔段86的内缘90。 The structure of each channel 82 comprises an outer edge 84, may actually be spaced planar section 86, and spaced toward the inner edge 86 of the segment 90. 该结构有助于任何固体(如污物、沙尘、碎石、锯屑、金属屑等)或液体(如水、油、油脂等)外来物进入空腔30。 This structure facilitates any solid (e.g., dirt, sand, gravel, sawdust, metal shavings, etc.) or liquid (water, oil, grease, etc.) into the cavity 30 of foreign matter. 外缘84可使外来物下落。 The outer edge 84 allows foreign objects fall. 要想进入空腔30,通气孔74,78的结构要求任何外来物首先穿透外壳18的外部,沿实际上是平面的86段移动,然后登上并通过内缘90形成的台阶。 To enter the cavity 30, the structure of the vent holes 74 and 78 require any external foreign objects penetrate the first housing 18, section 86 is actually moving along the plane, and then the board is formed by the inner edge 90 of the step. 这一弯路防止任何固体或液体外来物在没有外力作用时进入外壳18内。 This detour prevent any solid or liquid foreign objects into the housing 18 when no external force is applied. 然而, 如果外来物进入空腔30,这些外来物会通过排气孔50被排出。 However, if the foreign matter into the cavity 30, these foreign matters are discharged through the discharge hole 50.

[0065] 通常,在充电器10的工作过程中,充电电路58会发热。 [0065] Generally, during operation of the charger 10, the charging circuit 58 generate heat. 无需强制对流,冷空气会被从通气孔74吸入空腔30并流过发热的充电电路58。 Without forced convection, the cool air is sucked from the vent hole 74 and cavity 30 flows through the charging circuit 58 generates heat. 冷空气被充电电路58加热,使被加热的空气上升并通过通气孔78排出空腔30。 Cold charging circuit 58 is heated, the heated air rises and is discharged through the air hole 78 of the cavity 30.

[0066] 在其它结构(未示出)中,充电器10可以采用电动风扇而不是通过通气孔74,78 的无需强制的对流空气来冷却被发热的充电电路58。 [0066] In other constructions (not shown), the charger 10 may be employed instead of the electric fan to cool the charging circuit 58 is without heating by forced convection of air vent holes 74, 78. 诸如散热片、导热管等散热装置(未示出)也可用在充电器10中为充电电路58散热。 Such as a heat sink, a thermally conductive heat sink tube (not shown) may also be used for the charge circuit 58 in the charger 10 cooling. [0067] 如图11所示,外壳18被安装在底座94上,底座94是被设计用作沿其边悬挂外壳18并起缓冲作用的。 [0067] 11, the housing 18 is mounted on the base 94, the base 94 is designed for attachment housing 18 along its side and acting as a buffer. 在图示结构中,底座94是由高密度聚乙烯,一种强度很高且很能吸震的材料,采用吹塑工艺制成的。 In the illustrated construction, the base 94 is made of high density polyethylene, a kind of high strength and are able to shock-absorbing material made using a blow molding process. 这一选材使底座94能更有效地吸收冲击能量。 The selection of the chassis 94 can more effectively absorb the impact energy. 在图示结构中,底座周围采用约0. 1英寸的均勻壁厚,以底座94在坠落或受到其它冲击时破坏(尤其是在接近角部处)。 In the illustrated construction, a uniform wall thickness around the base employed is from about 0.1 inches to destroy the base 94 (particularly in the approach angle portion) when subjected to a fall or other impact.

[0068] 如图8所示,底座94还包括位于成形在底座94上的较低小区域102上的排气孔98。 [0068] As shown in FIG 8, the base 94 further includes a vent hole 98 on the base 102 is formed in the lower small region 94. 外壳18上的排气孔50和底座94上排气孔98是流体连通的但又相互错开的,从而无法通过排气孔50,98直接进入空腔30。 Vent hole 50 in the housing 18 and the base 94 is a vent 98 in fluid communication with each other but offset, which can not be directly through the vent holes 50,98 into the cavity 30. 如图9所示,排气孔98贯穿底座94,从而使任何进入充电器10的外来物可以被排出。 9, the vent hole 98 through the base 94, so that any foreign matter into the charger 10 can be discharged.

[0069] 如图1,11和13所示,手柄106与外壳18和底座94都相连。 [0069] FIG. 1, 11 and 13, the handle 106 with the housing 18 and the base 94 are connected. 手柄106通常位于接近充电器10前部电池14附着于电池槽70处。 Handle 106 typically located near the groove 70 of the battery charger 10 is attached to the front portion of the battery 14. 手柄106包括通过吸震的缓冲器114与外壳18相连的上部段110和与底座94相连的下部段118。 Handle 106 includes an upper section 114 through a shock-absorbing buffer 18 attached to the housing 110 and a lower section 94 connected to the base 118. 缓冲器114被设计成即能吸收也能阻抑震动。 I.e., buffer 114 is designed to absorb vibration can repressor. 缓冲器114由诸如聚氨脂或天然橡胶等粘弹性材料制成,具有弹簧和阻尼的双重特性,从而实现上述性能。 Buffer 114 is made of a viscoelastic material such as polyurethane or natural rubber or the like, having a dual spring and damping characteristics in order to achieve the above properties. 缓冲器114上有凹槽120。 A groove 120 on the buffer 114. 凹槽120分布在缓冲器114周围,使缓冲器114在受到冲击时更容易被压缩。 Grooves 120 distributed around the buffer 114, buffer 114 to make it easier to be compressed upon impact. 手柄中部有符合人机工程学的把手,使手柄106上有舒适、可靠而稳定的把手。 There middle handle ergonomic grip, the handle 106 has a comfortable, reliable and stable handle. 把手122可以包括弹性防滑材料制成的覆盖层,使充电器10可以被舒适地拿起。 Handle 122 may include an elastic covering layer made of a non-slip material, so that the charger 10 can be comfortably picked up. 在图示结构中,手柄106被制成由把手122连接的两部分。 In the illustrated construction, the handle 106 is formed in two parts connected by the handle 122. 然而, 在其它结构中(未示出),手柄106可被制成一体的,如一个杆,同时将把手122与手柄103 集成为一体。 However, (not shown) in other constructions, the handle 106 may be integrally formed, such as a lever, handle integrated with the handle 122,103 integrally.

[0070] 手柄106可以让使用者搬运充电器出入工地,不论电池14是否连接在充电器10 上。 [0070] The handle 106 allows the user to access the site transfer charger, whether the battery 14 in the charger 10 is connected. 如图6所示,附带的电池14通常被包围在由底座94和手柄106所确定的边界内。 6, with the battery 14 is typically enclosed within a base 94 and a handle 106 on the determined boundary. 这样,手柄106也起“栏杆”或保护装置的作用。 Thus, handle 106 also functions as "railings" or protection device. 更为特殊的是,手柄106的下部段118保护电池14的前面16c不受宽度大于手柄106下部段118尺度的面或物体的冲击。 More particular, the front lower section 118 of handle 106 to protect the battery 14 is greater than the width of the impact surface 16c from the object 118 or the lower section 106 of handle scales. 同样地,下部段118保护侧面16d不受其它大于下部段118与外壳18间距离的面或物体的冲击。 Similarly, the lower section 118 is protected from other side surface 16d is greater than the impact of the lower section 118 of the housing 18 or the surface of the object distance. 底座94保护电池14的底面16b不受坠落时的或其它形式的冲击。 Other forms of protection base 94 of the bottom surface of the impact when the battery 14 from falling or 16b.

[0071] 尽管电池14的顶面16a通过不受任何阻拦以便方便地装上或取下电池14,上部段110可给电池14的顶面16a提供一些保护以防止其受到宽于上部段110尺度的面或物体的冲击。 [0071] Although the top surface 16a of the battery 14 through without any blocking for convenient loading or removing the battery 14, the upper section 110 may be a top surface 14 to the battery 16a to provide some protection to prevent its being wider than the upper section 110 scales or impact the surface of the object. 在其它结构中(未示出),可采用附加的顶罩(未示出)保护电池14的顶面16a。 (Not shown) may be employed an additional top cover (not shown) to protect the battery in other constructions of the top surface 16a 14.

[0072] 如果充电器10坠落或在工地周围移动时受到冲击时,由于手柄106或底座94首先受到冲击,因而底座94与手柄106的组合有助于防止电池14在冲击作用下散开。 [0072] If the charger 10 drops and shocks when moving around the work, since the base 94 or the handle 106 first impact, and thus the base 94 in combination with the handle 106 of the battery 14 to help prevent spread on impact. 因此, 手柄106和底座94保护贮存在充电器10中的电池14不受冲击。 Thus, the handle 106 and the base 94 in the protection of stored battery 14 in the charger 10 from impact.

[0073] 在图示结构中,杆状手柄106为充电器10提供了保护结构。 [0073] In the illustrated construction, the handle 106 provides a rod-shaped protection structure 10 charger. 在其它结构中(未示出),保护结构可能包括一个固体壁,它从外壳18的外表面伸面并包围电池14的的表面使电池14位于该壁的凹槽中,同时又可以装卸电池14。 In other constructions (not shown), the protective structure may comprise a solid wall, which extends from the outer side surface of the housing 18 and surrounding surface of the battery cell 14 in the recess 14 of the wall, while detachable battery 14.

[0074] 在另一个其它结构中(未示出),一个或多个罩包围或部分包围电池14以保护其不受冲击。 [0074] (not shown), one or more shield surrounds or partially surrounds the battery 14 to protect it from further impact other constructions. 该罩或多个罩是可手工移去/伸缩或随电池14插拨。 Or more of the cover cap is manually removable / or telescoping the battery 14 with call waiting.

[0075] 缓冲器114也吸收一部分冲击能量,从而降低了电池14被震散的可能性和充电器10或充电器10的部件被破坏的可能性。 [0075] The buffer 114 may also absorb some of the impact energy, thereby reducing the likelihood of components of the battery 14 and the possibility Zhensan charger charger 10 or 10 is broken. 如图4所示,后部缓冲器126和侧面缓冲器130也被使用以分别协助保护外壳18。 4, the rear side buffer 130 and buffer 126 are also used to help protect the housing 18, respectively. 所示为一体结构的后部和侧面缓冲器126,130被固定外壳18上。 126, 130 is shown secured to the housing 18 and a rear side of the bumper integrated structure. 后部和侧面缓冲器126,130由抗冲击和能吸收能量的材料制成,如HDPE。 Buffers 126, 130 and the rear side and made of a material capable of absorbing impact energy, such as HDPE.

[0076] 如图11所示,第一面板22上设有开口以容纳多个电池槽70。 As shown in [0076] 11, the first panel 22 is provided with an opening to receive a plurality of grooves 70 cells. 在图示结构中,电池槽70设在充电器10上。 In the illustrated construction, the battery 70 is provided in the groove 10 on the charger. 在其它结构(未示出)及本发明的某些方面中,充电器10包括多于或少于三个的电池槽70。 In other constructions (not shown), and certain aspects of the present invention, the charger 10 includes more or less than three slots 70 of the battery. 如图17所示,每个电池槽70包括一个电池安装段138,一个充电端子装置142,以及一个安装段146。 As shown in FIG 17, each battery 70 comprises a battery mounting groove section 138, a charging terminal unit 142, and a mounting section 146. 电池安装段138包括用于在电池14嵌入电池槽70 时引导电池14的电池槽凸台150。 Battery mounting section 138 includes a battery 14 for guiding the battery slot 150 in the boss 14 when the battery 70 is embedded battery slot. 该电池槽凸台150与电池14上匹配的电池凹槽154咬合(如图27中所示)以为电池槽70提供正确的排列位置并支撑电池槽70。 The battery slot 150 and the boss 14 on the battery cells matched engagement recess 154 (shown in FIG. 27) that the battery container 70 to provide the proper arrangement position and supporting the battery slot 70. 同样地,电池凸台155嵌入匹配的电池槽凹槽156以为槽70提供正确的排列位置并支撑电池槽70。 Similarly, the boss 155 of the battery cell fitted recess grooves 70 matching grooves 156 that provide a correct position of alignment groove 70 and support the battery. 如图14-16所示,一组充电端子66 (充电端子装置142的一部分)隐藏在槽70上的端子基座158内的开口中。 14-16, a set of charging terminals 66 (a portion of the charging terminal unit 142) opening in the terminal base hidden in the groove 70 158. 导电凸台162连接充电电路与相应的槽70上的充电端子66。 Conductive boss charging circuit 162 is connected to the corresponding charging terminals 66 on the groove 70. 安装部分146还包括连接槽66与外壳18的固定器166。 The mounting portion 146 further includes a groove 66 connected to the housing of the fixture 16,618.

[0077] 槽70与外壳18间的连接足够坚固,即使充电器10在带有电池14时坠落,相应的槽70也不会与外壳16分开。 [0077] The connection 18 between the groove 70 and the housing is strong enough, even when the fall in the charger 10 with a battery 14, a respective groove 70 does not separate from the housing 16. 电池槽14的设计要求其能够承受在带有电池14时从4英尺高处坠落而不与外壳分离。 Design requirements which the battery slot 14 with the battery able to withstand falls from four feet without separation from the housing 14.

[0078] 至少充电器10中与电源连接的部分要由耐火材料,如νΦ级塑料,制成。 Portion [0078] at least the charger 10 to be connected to the supply of a refractory material, such as νΦ grade plastic, steel. 这些部分包括充电电路58及安装平台62装置和电池槽70。 The charge circuit portion 58 includes a platform 62 and mounting means 70 and the battery slot. 因此,外壳18的其它部分可由其它材料制成。 Accordingly, other portions of the housing 18 may be made of other materials.

[0079] 在图示结构中,如美国专利No. 6,222,343和No. 6,456,035中所述,电池14向充电电路58供电以启动充电。 [0079] In the illustrated construction, such as U.S. Pat. No. 6,222,343 and No. 6,456,035 in the battery 14 to charge the power supply 58 to start charging circuit. 即使充电器10与电源相连,如果电池14不与端子66连接,则端子66不会通电。 Even if the charger 10 is connected to the power supply, if the battery 14 is not connected to the terminal 66, the terminal 66 is not energized. 因此,如果电池14没有放入一个槽70中,则相应槽70的端子66的间电压为零。 Therefore, if the battery 14 is not placed in a groove 70, the voltage between the corresponding groove 70 of terminal 66 is zero. 这有助于确保充电电路58在槽70中没有放入电池时不会被短路,同时减小了电池14未放入时电击事故的危险。 This helps ensure that the charging circuit 58 is not short-circuited when the groove 70 is not in the battery, while reducing the risk of electrical shock when the battery 14 is not placed.

[0080] 如图17-21所示,每个电池槽70还包括一个充电端子罩170,如图中所示结构,在弹簧作用下覆盖端子基座158。 [0080] As shown in FIG 17-21, each slot 70 further includes a battery charging terminal cover 170, as shown in the structure, the terminal base cover 158 under spring action. 如图22和23所示,充电端子罩170包括一个每侧分别带一个安装转柄178的防护罩。 As shown in FIG. 22 and 23, a charging terminal cover 170 comprises a belt mounted on each side of each crown guard 178. 每个转柄178上有一个位于防护罩174与轴186间的接线夹182,在这里罩172与槽70连接。 Each have a crown 178 located between the terminal 174 and the shield clamp 182 shaft 186, the cover 172 where the groove 70 is connected. 图15和20-21所示为罩170与槽70装配在一起。 20-21 is shown in FIG. 15 and the groove 70 and the cover 170 are assembled together. 偏置元件,如图中所示的扭转弹簧190,被放置在槽70与安装转柄174间以偏置防护罩174使覆盖在端子基座158的开口上。 The biasing member, the torsion spring 190 as shown in the figure, are placed in the groove 70 and the crown 174 is mounted to bias the shield to cover the opening 174 so that the terminal base 158.

[0081] 如图中所示,将电池14滑到电池安装段138上的操作使端子罩170轴向退缩从而打开端子基座158的开口并将端子138显露在电池14前面。 [0081] As shown, the operation of the battery 14 on the battery mounting section 138 is slid so that the terminal axial back cover 170 to open the opening 158 and the terminal 138 of the terminal base 14 exposed in front of the battery. 需要特别指出的是,电池安装段138包括一个开口194,接线夹182通过它凸出。 Of particular note, the battery mounting section 138 includes an opening 194, 182 through which the connecting terminals protrude. 电池凸台155与接线夹182配合进而与电池安装段配合。 Battery clip boss 155 and wiring 182 in turn mate with mating battery mounting section. 接线夹182包括一个斜面,足以使端子罩170轴向地抵消弹簧190的偏置力,从而使端子基座158和端子66显露在电池14前面。 Binding clip 182 includes a ramp, the terminal cover 170 is sufficient to counteract the axial direction of the biasing force of spring 190, so that the terminal base 158 and the terminal 66 exposed in front of the battery 14. 当电池14被取走,弹簧190的力使罩170轴向回到能够覆盖端子基座的位置。 When the battery 14 is removed, the force of the spring 190 back to the axial position of the cover 170 can cover the terminal base. 偏置力足够关闭罩170而又不阻碍电池14 的装入。 Sufficient biasing force of the closure 170 without impeding the battery 14 charged.

[0082] 如图10所示,端子罩170在被电池14的插入推动时退缩进空腔30内。 [0082] As shown in FIG. 10, when the terminal cover 170 is inserted into the battery 14 is pushed back into the inner cavity 30. 罩170沿着清扫开外来物并清洁槽70与电池14的界面的路径移动。 Cover opening 170 along the cleaning foreign matter 70 and the cleaning tank moving path 14 of the battery interface. 端子罩66还有助于使端子66 尽可能少地暴露在外部环境中。 Terminal cover 66 also helps to terminal 66 as little as possible exposed to the outside environment. 关闭时,端子罩170使外来物(如污物、沙尘、水、油、油脂等)从粘附在端子66上的位置下落并减小对充电电路58和电池14间电连接的不利影响。 When closed, the terminal cover 170 so that foreign matter (e.g., dirt, dust, water, oil, grease, etc.) adhered to the drops from the position of terminal 66 and reduce the adverse effects on the charging circuit 58 and the battery 14 is electrically connected . [0083] 在其它可选结构(未示出)中及本发明的其它方面,端子罩170可以其它方式移动,如线性地从端子基座上滑开,而不是在电池14与电池安装段138配合时轴向离开端子罩158。 [0083] In another alternative construction (not shown), and other aspects, the terminal cover 170 may be moved in other ways, such as linearly slid from the terminal base of the present invention, instead of the battery 14 and the battery mounting section 138 when terminal cover 158 axially away from mating. 此外,端子罩170可以按用户的要求动作,如按下一个按钮可以使端子罩170退缩。 Further, terminal cover 170 may be required user action, such as pressing a button of the terminal 170 back cover.

[0084] 如图28所示,多种充电终止协议,包括温度等级(TR)终止协议,及固定模块,包括涓流充电模块198,充电模块202,及一个平衡模块206,提供了充电过程的控制。 [0084] 28, more charge termination protocols, including temperature rating (TR) to terminate the agreement, and the fixed module comprising trickle charging module 198, a charging module 202, and a balancing module 206, a charging process control.

[0085] TR充电终止协议监测一个充电周期中电池14温度升高的速度,并在电池14达到预定的温度变化速度时切断充电电流。 Cut off the charging current when the [0085] TR charge termination protocol monitoring a charging cycle of the battery 14 temperature rise rate reaches a predetermined temperature and the rate of change in the battery 14. TR协议还能考虑导致电池14在切断电流后温度继续升高的热滞后。 TR protocol also considerations lead 14 heat continues to rise after cutting off the current battery temperature hysteresis. TR协议可以减少充电时间,控制由于充电引起的发热,并延长电池寿命。 TR protocol can reduce the charging time, since the heat generation due to charging control, and extend battery life.

[0086] 固定执行代码监测电池14的正常充电周期。 [0086] Fixed monitor code execution normal charging cycle of the battery 14. 充电周期可被前述TR终止协议终止。 Charge cycle may be terminated the termination TR. 正常充电周期的终止会启动执行与涓流充电模块198有关的代码。 Terminating the normal charging cycle starts with the trickle charge execution module 198 relating to the code. 涓流充电模块198可在软件中设置与正常充电周期结束和涓流充电模块198启动相关的“涓流充电”标志。 Trickle charge module 198 may be provided with a normal charging cycle is completed and the trickle charge module 198 to start the associated "trickle charge" flag in the software. 设置“涓流充电”标志启动充电模块202和平衡模块206。 Settings "trickle charge" flag to initiate a charge balancing module 206 and module 202. 充电模块202可以借助于作用于电池14的大约每两分钟五秒的脉冲电流对电池14施加持续的充电。 Charging module 202 may be applied by the action of continuous charging of the battery 14 to a pulse current of about five seconds every two minutes of battery 14.

[0087] 平衡模块206执行可以使电池14休息并冷却十五分钟并设置平衡发生的时间限制的代码。 [0087] module 206 performs balancing of the battery 14 can be cooled and fifteen minutes of rest in the code set and the balance of the time limit. 如果平衡模块206在限制时间内不执行,该模块终止并充电模块202继续保持充电。 If the balancing module 206 is not performed within the time limit, the module terminates and the charging module 202 remain charged. 同时在限制时间内,一个传感器监测电池14的温度。 While within the time limit, a temperature sensor 14 monitors the battery. 如果温度在可以接受的范围内,软件中会设置“快充”标志。 If the temperature within the acceptable range, the software sets the "quick-charge" flag. 设置“快充”标志会启动一个快速充电周期,其中最大持续充电时间由“快充时间”来设定。 Settings "quick-charge" sign starts a rapid charge cycle, the largest continuous charging time set by "fast charge time." 快充时间通常是5分钟,然而,根据电池14的种类和容量的不同也可以是其它时间。 Fast charge time is usually 5 minutes, however, depending on the type and capacity of the battery 14 may also be other times. 不管是快充时间还是其它充电终止协议之一,如TR协议,都能终止快充周期。 Whether fast charge time of one or other charge termination protocols, protocols such as TR, may terminate the fast charge cycle. 如果在充电终止协议执行前快充时间就已到期,则平衡模块206终止且充电模块202继续持续充电。 If the fast-charging before the charging is terminated protocol execution time had expired, the balancing module 206 continues to block 202 to terminate charging and continuous charging.

[0088] 平衡模块206每个充电周期执行一次且适合于按电池100%的容量对其进行充电。 [0088] balancing module 206 is performed once per charging cycle and adapted to 100% of the capacity of the battery to charge it. TR终止协议控制平衡模块206执行过程中的充电电流水平。 TR termination protocol control module 206 performs the charge balancing during current level. 其发热速度的水平通常低于正常充电周期中的水平。 Horizontal level below which the heating rate is generally normal charging cycle. 以较小发热速度提供充电电流可使电池14在充电时的热应力最小的情况充电容量更接近于其最大容量。 A smaller heat release rate can provide a charging current of the battery case 14 with minimal thermal stress at the time of a charging capacity closer to its maximum capacity.

[0089] 以镍金属氢化物(NiMH)为例,一个NiMH电池采用TR终止协议在正常电流水平(约3. Oamps)下充电。 [0089] In a nickel metal hydride (NiMH), for example, a NiMH battery using normal charging TR protocol termination current level (about 3. Oamps). 充电终止时其温度应为40°C,或室温以上15°C。 Charge termination temperature should be 40 ° C, or above room temperature 15 ° C. 由于热滞后,NiMH 电池在充电后15-30分钟间仍会继续升温,通常其温度会再上升5-7°C。 Since the thermal hysteresis, NiMH battery after charging will continue to heat between 15-30 minutes, typically it will further increase the temperature of 5-7 ° C.
