Charging service vehicles and methods using modular batteries
First Claim
1. A service vehicle comprising:
- a vehicle;
electric vehicle (EV) charging equipment transported by the vehicle;
two or more battery modules removably mounted to the vehicle, the battery modules electrically connected to the EV charging equipment as a source of electrical energy for the EV charging equipment, wherein the EV charging equipment is configured to provide charge to an EV from the battery modules;
wherein the EV charging equipment is configured to sequentially draw energy from each of the two or more battery modules, wherein energy is drawn from battery modules having a lower state of charge before energy is drawn from battery modules having a higher state of charge.

Abstract
Charging service vehicles and methods using modular batteries are disclosed. The service vehicles are vehicles having electric vehicle (EV) charging equipment, and removably mounted battery modules or battery module connection points. The battery modules are connected to the EV charging equipment as a source of electrical energy. Some embodiments disclose integrating the EV charging equipment with the vehicle, recharging modules through a distribution grid connection, the manner of discharging the batteries, modes of connecting and disconnecting the modules, the size and weight of the modules, quick-disconnectability of modules, control and monitoring of the modules and charging equipment, and/or ways of connecting modules to the vehicle. These features are beneficial to efficiently keep service vehicles available for EV charging through exchanging battery modules or providing additional battery modules when necessary, and may keep operators safe through de-energization of connectors and other precautions inherent in these designs.
