Storing Your Electric TOMCAR®
If your vehicle is to be placed in extended storage the following steps should be taken to preserve its condition and
traction battery health:
1. Perform all necessary repairs and thoroughly clean the vehicle.
2. Remove and store the auxiliary battery according to page 85.
3. Raise the vehicle so all tires are suspended off the ground.
4. Spray oil on unpainted metal surfaces to prevent rusting. Avoid getting oil on rubber parts or in the brakes.
5. Lubricate cables.
6. Cover the vehicle with a canvas. Do not use plastic material, since they do not allow ventilation.
7. Traction battery storing:
a. All batteries will self-discharge over time. The rate of discharge varies depending on the ambient
temperature and battery age and condition.
b. Traction battery is to be stored above 0
o
and below 40
o
Celsius.
c. For long durations (more than a month), it is best to store the traction battery at around 50% SOC.
d. It is important to check battery SOC every 4 weeks and recharge if SOC drops below 10%.
e. A special storing charger can be purchased and left connected to the traction battery, provided the
charger is plugged into an active electrical source.
if the source power to the charger is disconnected or interrupted the battery management system will
keep checking the batteries, this will draw power from the battery pack and eventually drain the
batteries if power is not restored in a timely manner.
This procedure requires the auxiliary battery to be connected in the vehicle.
