Battery Modules, BMS & Charger
This section of the owner’s manual covers the onboard Battery Modules, Battery Management System and the Charger. All
information regarding charging and keeping your Enertia’s batteries in peak operating condition will be covered here.
Your Enertia is equipped with:
1. Six (6) rechargeable Lithium-Ion Battery Modules. These battery modules use Lithium Phosphate Technology that provide
the lithium-ion advantages of high energy, light weight, and long cycle life without the fear of thermal runaway event
under abuse conditions.
Each battery module is rated at 512Whr for a total of 3.1KWhr onboard. Each of the 6 battery
modules contains 4 cell stacks for a total 24 onboard cell stacks. Each cell has a nominal cell voltage of 3.3 volts for a total
battery stack voltage of just under 80 volts. Under normal operating conditions, your Enertia’s battery modules are rated
for thousands of charge cycles.
2. A Battery Management System (BMS) monitors each battery module’s state of charge, current, cell voltage and
temperature.
3. An onboard charger designed to operate from a standard 110V (or 220V using a optional power cord) household outlet.
Normal charge time is just over 4 hours if the batteries are fully depleted.
Maximizing Battery Capacity and Battery Life
By following the tips listed below, one can assure long life and high performance of your Enertia’s Battery Modules.
•
Operate your Enertia at temperatures below 104
°
F (40
°
C), charge at temperatures between 32
°
F (0
°
C) and 113
°
F (45
°
C).
•
Cell balance as often as possible. Battery module cell variability and environmental conditions can cause slight state of
charge imbalances between cells. After the normal charge cycle (batteries charged to 99%), cell balancing starts. During
cell balancing, the battery modules, BMS and charger attempt to perfectly match all of the cell voltages. Leaving your
Enertia powered up in charge mode with A/C power connected will maximize your battery modules’ performance when
not in use.
•
Charge battery modules fully prior to long term storage.
• Charge battery modules fully if it has been stored for more than three (3) months.
