Page 14 ecolader: rapid discharger/charger series 8.8 Termination temperature Description: This function has a dual purpose: it provides extra safety when the charge is terminated using the (voltage) peak detection feature. It can also be used as an independent method of "battery full" charge termination. Activating the menu point: Press the akku x button. Select value: Press the + or - button. Value range: 23° C ... 45° C ... 50° C. Fixed temperature values: 41° C, 65° C (see notes below). Confirm value: Press enter Interrupt: Press esc Notes: The temperature limit values can be set separately for each battery, but the charger only has one temperature sensor, which must be activated on a battery-specific basis under the menu point Charge Termination Criterion (see Section 8.12). In addition a fixed, non battery-specific temperature value of 65° C is active for the whole device during every charge and discharge process as an "emergency power cut-off" system. Simply push the temperature sensor into the battery to be monitored. Moreover there is a non-selectable temperature limit of 41° C which delays a discharge process involving a battery above this temperature until it cools down to below this value; this only applies if temperature termination has been selected. The temperature sensor should be plugged into the socket marked cal on the ecolader +. 8.9 Termination delay Decription: This function is useful with cells which really refuse to be charged by erroneously tripping the peak detection system. It does this by charging for the first few minutes without checking the voltage peak. Activating the menu point: Press the akku x button. Select value: Press the + or - button. Value range: 1 min ... 8 min ... 10 min. Confirm value: Press enter Interrupt: Press esc Notes: However, since the automatic charge termination system is very reliable in operation, and since a wide variety of termination criteria are taken into account and analysed, this function only needs to be activated in very rare cases. Entering a delay time does not immediately result in a delayed activation of the automatic charge termination system. This has to include the additional "del." component in the termination criterion (see Section 8.12).

ecolader: rapid discharger/charger series Operating instructions for software V1.04, date of issue 05 MAY 1998 8.10 Termination check count Description: This function is used to configure the automatic charge termination system. Checks on the probability of the battery being fully charged are made at 30-second intervals after the first peak is detected. The battery is only considered to be full when the test result is positive over the desired number of checks, and the charge current is then switched off. This means that brief variations in battery voltage due to cell "noise" or other effects do not result in premature charge termination. Note that too many checks prolong the test period and allow the battery to heat up more than is necessary. Activating the menu point: Press the akku x button Select value: Press the + or - button Value range: 2 x ... 3 x ... 7 x (at approx. 30 s intervals) Confirm value: Press enter Interrupt: Press esc Caution: Do not change this parameter unless you understand exactly how the system works! Notes: The number of termination checks works hand in hand with charge termination sensitivity and the fixed check time interval. Three checks with a sensitivity of 3 mV / cell, using a 6-cell pack and a test period of about 90 seconds, produce a minimum voltage drop of: 3 mV * 6 cells * 3 checks = 54 mV The actual voltage drop is usually higher (100-400mV). If the batteries are too hot after the charge termination, you should reduce the number of checks to 2 (e.g. if you are charging at more than 6 A). If they are too cold, the number of checks can be increased to 7. When pulsed charging is in use, the charge is terminated after 5 checks at most. schulze elektronik gmbh Page 15 8.11 Termination sensitivity Description: This function is used to configure the automatic charge termination system. The likelihood that a battery is fully charged varies according to the magnitude of the voltage drop after the peak. This voltage drop must be greater than the set sensitivity over the time period of about 30 seconds (fixed internal period) if the battery is to be recognised as fully charged. Caution: This parameter prevents erroneous premature terminations. It is not designed to charge a battery "fuller than full" by setting high values. Please see also Section 8.10. High values reduce the possibility of erroneous terminations, but may not be achieved by the battery under certain circumstances due to low charge currents (owing to the automatic current calculation system towards the end of the charge) with the possible result that the battery could be overcharged. The sensitivity value you enter refers to a single cell, i.e. a 6-cell pack will exhibit six times the value. This value is calculated by the automatic charge termination circuitry based on the calculated number of cells. Activating the menu point: Press the akku x button. Select value: Press the + or - button. Value range: batt. 1, 2: 0 mV ... 3 mV ... 5 mV (per cell). batt. 3: 0 mV ... 1 mV ... 5 mV (per cell). Confirm value: Press enter Interrupt: Press esc Notes: Hybrid cell batteries (Panasonic, yellow Sanyo) should be charged with the sensitivity reduced to 1 mV. Nickel Metal Hydride batteries should be charged with the sensitivity reduced to 0 (zero), and a fixed current setting of about 0.5 to 1 C. schulze elektronik gmbh • prenzlauer weg 6 • D-64331 weiterstadt • tel: 06150/1306-5, fax: 1306-99 internet: http://www.schulze-elektronik.com e-mail: mail@schulze-elektronik.com
