Mostly a battery room is necessary at a two or three shift operation, normally recharged batteries and batteries under charge stand in front of one charger. In battery charging stations normally trucks with installed batteries are connected to the chargers. Also both different versions could be installed in one room. 重要的是房屋是否是一个有人负责对电池管理、维护和充电的工作场所。这样必须有专门规定，如灯光、噪音、温度、气体释放等等，是否还要有附加等候室、清洗室和休息室。 Important is if the room is a working place where persons are in charge to optain and maintain and change batteries. In this case special regulations for working places are necessary, for example questions about light, noise, temperature, gas-emission and so on, additional waiting rooms, wash rooms and rest rooms had to be installed. 2. 建筑结构 Building constructions 2.1充电站里的车辆空间 Truck place in charging stations 总则 General 充电站的平面空间取决于充电站规模和车辆种类，而且根据VDI 2197, 2198 和 2199或国家特殊标准计算车辆进、出和转弯的必备空间。 The necessary square meters of charging stations depends in the main part of the kind of charging station and the trucks, also the necessary space for drive in and out and turn around with the trucks must be calculated according the regulation VDI 2197, 2198 and 2199 or special national norms. 实际可以用15 m2 计算，重要的是 - 车辆的种类和外形尺寸 - 每个车型的车辆数量 - 车辆总数量 - 充电机的数量和种类 - 车辆占据的面积（宽和深） - 车辆高 In practice you can calculate with 15 m2 square meters, important are - kind and largeness of the trucks - quantity of trucks of each truck type - total quantity of trucks - quantity and type of chargers - the stand square meters of the truck wide and deep - high of the truck 车辆附加的占地面积，必须将车辆周围空间0.6 m 和充电机到电池间1m的距离计算在内。 Additional to the stand square meters of the trucks a necessary space around the truck of 0,6 meters and a distance charger to battery of 1 meter must be calculated. 车辆到充电机和存储的货物之间最小距离 Minimum distances of trucks to chargers and stored goods a 车辆周围必备空间 necessary space around the truck最少 0,6 meter b 电池和充电机间必备距离 necessary distance between battery and charger最少1 meter c 到易燃品的必备距离 necessary distance to inflammable stored goods最少2,5 meter d 到易爆品的必备距离 necessary distance to explosive material最少5 meter 必备高度取决于车辆 necessary high of the place depends of the trucks最少2 meter 充电站的房屋布局 Room arrangement at a charging station 相对放置的车辆间必备距离应该是车辆转动空间的一半（Wa）加上0.6m B Wa 0,6m necessary distance between the opposite placed truck should be the half of the turn B around space Wa of the truck plus 0,6 meterB Wa 0,6m 2.2电池房的空间Place in battery rooms 电池充电房的必要面积取决于电池、充电机、起重设备或运输充放电电池的车辆的种类、数量和大小。 In battery charging rooms the necessary square meters depends of the quantity and the largeness of the batteries and the chargers and of the kind of crane or the change-wagon to handle the recharged and the discharged batteries 实际上，可以用7 m2计算 In practice you can calculate with 7 m2 每个充电机前必须计算出必备空间， 以放置两个电池加上电池之间最少0.2m的通风空间。 In front of each charger the necessary place must be calculated for two batteries plus a distance of minimum 0,2 meter between the batteries to have a good ventilation during charge. 放电池的托架必须以最重的电池考虑计算，并且与地隔离。 Battery banks must be calculated for the heaviest battery and must be isolated against the ground. a 充电机前面板到电池的最短距离a为0.5m，电池到温度超过200C的加热装置最短距离为2.5m。 The minimum distance a of the charger front panel to the battery is 0,5 meter and minimum 2,5 meter between battery and heating systems with a temperature more than 200C 2.3地板要求 Floor conditions 地板上应该盖有一层防酸材料 压强 8 N/mm 抗酸腐蚀抗硫酸H2SO4 50 泄漏电阻100 kohm 墙 泄漏电阻100 kohm 电池周围1.5m。 屋顶 抗酸腐蚀抗硫酸t H2SO4 50 地板必须有一个最小0.25 m3 坑，其周围斜度为1 。 The floor should be covered with an acid resistant material Pressure solidity 8 N/mm Acid solidityagainst H2SO4 50 Divert resistance100 kohm Walls Divert resistance100 kohm only around the place of the batteries 1,5m Roofs Acid solidityagainst H2SO4 50 The floor must have a Gradient of 1 to a pit of minimum 0,25 m3 3.电气安装 Electrical installation 总则 General 按照DIN VDE 0100或专门国家标准或根据充电机供货商的说明进行电气安装，应具有市电电源断路器、为每个充电机安装带慢动作熔丝的电源断路器或电机电路自动空气开关。应该具有通风并规定只有工作通风时才能充电。 The electrical installation is to be done according DIN VDE 0100 or special national norms with a main switch power breaker and each charger with a power breaker with slow acting fuses or automatic breakers for motor-rated circuits according the technical instructions of the supplier of the chargers. With a ventilation it should be installed a regulation that only with a working ventilation a charge is possible 3.1视在功率 Apparent power 视在功率计算必须包括下列项目 - 充电机 - 加热系统 - 通风 - 照明 For the calculation of the apparent power the following components must be included - chargers - heating systems - ventilation - illumination 充电机1到n的视在功率计算 根据供货商的信息，功率P1, P2, ....Pn P 总功率 P1 P2 ...

The chargers are either wall mounted or floor mounted depending of the largeness of the chargers. Important is also a distance between the chargers of minimum 0,2 meter to get a good ventilation of the air. The mounting high should be selected that a good operation with the chargers is possible. Any installation of water must be below the chargers. Example for wall mounted chargers 例如，墙上安装充电机 5.通风Ventilation 5.1总则 General 因为电解液的水分离在电池腔内形成氢氧混合气体，这个过程是在接近电池充电结束时，即电池过充时发生 的，超过过充电压就开始放气阶段。 要设计电池充电房和充电站有足够的自然通风，如果需要强迫通风，就应该在始开充电时接通通风装置，进风尽可能的接近地面，经过电池然后尽可能高的从对面排出。 A battery cab a gas mixture of hydrogen and oxygen due to the electrolytic decomposition of water. This gas develops particularly towards the end of battery charging or if the battery is overcharged. It is at it greatest above the voltage at which gassing starts. Battery charging rooms and battery charging stations shall where possible be designed so that the natural ventilation is sufficient. If artificial ventilation is necessary, it shall be ensured that the ventilation is switched on whilst charging is taken place. The inlet air shall enter as close as possible to the ground, pass over the batteries and escape as high as possible on the opposite side. 5.2根据DIN VDE 0510 第三部分计算 Calculation according DIN VDE 0510 part 3 电池充电房和充电站的通风，在充电时要考虑到至少有足够的空气流量Q,Q由以下公式决定 The ventilation of battery rooms and charging stations is regarded as adequate if during charging at least the volume of airflow Q, determined according to the following equation, is guaranteed.

Are these climate conditions not to realise so the used equipment had to be fit out for example air condition for the chargers or heating tables for the batteries. For this the supplier of the equipment can give ination’s. 7. 加水 Water topping 带液态电解液的电池，由于充电时会引起放气过程而失去水分，必须再加水，根据DIN 43530或国标必须加蒸馏水，一般的水会破坏电池。 由充电极控制的不需维护的自动加水系统对电池加水有益，在充电结束前的适当时间进行短时加水，电池必须有专门的添满自关闭装置 。 自动加水系统的压力应该是最小 0.2
