Energy storage & charging
description:
4 metal boxes which include battery cells,
BMS and communication modules,
power and signal connectors
battery capacity:
(standard configuration)
4.75 kWh
battery capacity:
(optional configuration)
7.10 kWh
useful bat. capacity (recommended, std)
3.8 kWh
useful bat. capacity (recommended, optional)
5.7 kWh
CAUTION!
IN ORDER TO PROLONG THE BATTERY LIFE, IT IS NOT RECOMMENDED TO
DISCHARGE THE BATTERY BELOW 20% CHARGE. USEFUL RANGE IS CONSIDERED TO BE BETWEEN
20%-100% OF SYSTEM CHARGE.
CAUTION!
FOR BATTERY PROTECTION, THE ESYS-MAN WILL CUT THE POWER (AFTER A
WARNING) AT 10% BATTERY CHARGE. THE REMAINING IS USED FOR MOTOR RETRACTION AND
POWER SUPPLY TO AVIONICS.
The batteries are organized in 4 metal boxes, which include the battery cells, the Battery
Management System, communication modules as well as power and signal connectors. Two of the
boxes are positioned behind the fuselage bulkhead, two are in front of the same bulkhead.
Make sure that all the connectors (2x power connectors, 2x CAN BUS connector per box) are fas-
tened properly before each flight.
For storage, it is recommended to disconnect the RED (+) power connector on the box behind the
cockpit section. This will physically disconnect the high-voltage part of the propulsion system. Make
sure you reconnect the battery before next flight.
Battery management system
Each of the battery boxes have an independent BMS, monitoring and balancing system voltage. All
units communicate to the ESYS-MAN and log data from each individual battery cell. In case of an
error, ESYS-MAN will display a message (error code). Contact Pipistrel if this happens. Under normal
circumstances the BMS requires no human intervention and is a fully automated system that takes
care of itself.
Battery system
Standard

CAUTION!
TEMPERATURES BELOW 10°C WILL RESULT IN DECREASE OF BATTERY CAPACITY.
PLAN YOUR FLIGHT ACCORDINGLY.
WARNING!
DO NOT, UNDER ANY CIRCUMSTANCES, ATTEMPT TO CHARGE THE BATTERIES
WITH ANY THIRD PARTY CHARGERS. ONLY PIPISTREL ORIGINAL EQUIPMENT MUST BE USED.
WARNING!
RESPECT OPERATING AND STORAGE TEMPERATURE LIMITS AT ALL TIMES.
FAILURE TO DO SO MAY RESULT IN BATTERY DAMAGE.
