16、 Standard. The reference document was submitted to the CENELEC members for formal vote and was approved by CENELEC as EN 61044 on 15th september 1992. The following dates were fixed: Annexes designated “normative” are part of the body of the standard. In this standard, Annex ZA is normative. latest

18、 time during a working period to top up the charge and thus extend the working day of a battery whilst avoiding excessive discharge. The object of this report is to lay down rules or recommendations for the use of opportunity-charging of traction batteries. NOTEWhen opportunity-charging enables the
19、user to draw substantially more than 80 % of the rated capacity of the battery each day, battery-life measured in terms of energy-exchange should remain about the same. In consequence, this battery-life measured in years, can be reduced. Opportunity-charging may result in higher working temperatures
20、; this may further reduce battery-life. It is essential, therefore, to discuss the proposed operation with the battery manufacturer as modification of his normal guarantee may be necessary. 2 Normative references The following standards contain provisions which, through reference in this text, const
21、itute provisions of this Technical Report. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this Technical Report are encouraged to investigate the possibility of applying the most recent editions of the standard
22、s indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

24、cally in Figure 1a and Figure 1b. 4 Planning The following points should be considered when planning to introduce opportunity-charging: 4.1 Indications that opportunity-charging may be beneficial 4.1.1 When the maximum permissible size of battery for the vehicle does not have enough capacity to do t
25、he work required. 4.1.2 When the operational requirements of the vehicle are such that it is impossible to predict when it will next be released for a complete recharge (e.g.places such as airports where 24 h working is the rule). 4.1.3 When a battery is close to the end of its life and the use of o
26、pportunity-charging can be shown to be maintaining its work period. NOTEIf the periods available for charging are of short duration and infrequent, then opportunity-charging will be of little benefit. 4.2 Opportunity-charging should not be used 4.2.1 When the battery is able to cope with the load wi
27、thout extra charge whilst operating within the battery manufacturers recommendations. 4.2.2 When the working pattern of the battery and the charger system does not conform to the recommendations of clause 5. 5 Operational procedures The following points should be considered when operational procedur
28、es are being generated: 5.1 Self-compensating chargers shall be preferred for use with opportunity-charging. A correctly sized battery/charger combination is essential. NOTEWhere a known duty cycle exists, a calculation of the energy balance is recommended. It should be established that adequate cha
29、rging periods are available for opportunity-charging.EN61044:1992 4 BSI 09-1999 5.2 One period of regular charge in every working day should be provided during which the battery is allowed to complete its charging cycle in order to prevent deterioration of the state of the battery. 5.3 During opport
30、unity-charging, battery ventilation precautions shall be applied. 5.4 If during any charging period, the battery (electrolyte) temperature exceeds the manufacturers recommendation, then the charging shall be stopped until the battery has cooled down (with or without forced air ventilation). This imp
31、lies that means for measuring the temperature of a battery shall be available to the operating personnel, as well as information on the upper temperature limit set by the manufacturer. 5.5 Additional operational limitations using other chargers: Opportunity-charging shall only be applied if the batt
32、ery has been discharged by at least 30 % of its nominal capacity.EN61044:1992 BSI 09-1999 5 Figure 1a Discharge/recharge and partial discharge/recharge Figure 1b Partial discharges/partial recharges final recharge Figure 1 Schematic patterns of a 24 h (daily) battery dutyEN61044:1992 6 BSI 09-1999 A
