EV Battery Designs for Easier Replacement

System for determining when to replace battery modules in vehicles based on calculated life estimations, enterprise acceptability values, and maintenance schedules. The system involves monitoring battery health parameters using onboard sensors, collecting vehicle and environmental data, analyzing the data to calculate battery life and health, comparing against enterprise acceptability thresholds, and communicating replacement determinations to the vehicle. This allows proactive replacement planning and optimization rather than waiting for failures.

Displaying remaining life information for a battery system with replaceable modules to help optimize replacement decisions. The system calculates the current remaining life of the battery system based on the state of health (SOH) of all modules. It also calculates an extended remaining life if some modules are replaced with new ones. This extended life is shown alongside the current life to give users a comparison of how much extra life they could get by replacing modules versus keeping them. The user interface allows toggling between the two life estimates.

Battery management system for optimizing battery replacement in devices like electric vehicles. The system calculates the maximum current rate a replacement battery can handle based on its capacity and deterioration level. It then selects a replacement battery with an estimated maximum current rate matching a predetermined threshold. This ensures the new battery can handle the device's expected usage without excessive deterioration. The current rate calculation uses the original battery's usage history and expected usage period.

Battery storage device for vehicles that allows inserting and removing EV batteries in a way that avoids damaging the terminals. The battery case has a mechanism to displace the case side terminal away from the battery terminal when inserting/removing. The mechanism is operated using a lever that first retracts the case terminal, then locks the battery in place. This prevents contact between the terminals until after insertion, avoiding damage if the battery is inserted roughly.

Battery pack case for electric vehicles that allows easier and cheaper replacement of worn or damaged parts. The case uses a bolt and nut coupling instead of welding. The bolt attaches to the vehicle frame, with a first nut tightening onto it and a second nut tightening onto the first nut. This provides a secure connection without welding. When the battery pack is repeatedly attached and detached, only the nuts may wear out or get damaged. By avoiding welding, these nuts can be easily replaced instead of the entire frame, reducing maintenance cost.

Battery installation device for a battery pack that allows the electrical connector to be quickly and easily installed and positioned inside a limited space battery case. This is achieved by a sliding bracket connected to a base that is fixed to the battery case. The electrical connector is assembled onto the bracket. The bracket can slide relative to the base along the height direction of the battery. This enables the connector to be inserted into the case, then the bracket slid down to secure it. This allows connector installation in a confined space without pre-drilled holes or ties.

Method and device for optimizing battery swapping in electric vehicles by analyzing historical vehicle and station data to provide battery replacement strategies that reduce total charging and shorten swapping times. The method involves generating historical energy recovery rates for each vehicle based on past swapping station data. Then, using vehicle and station data along with the recovery rates, it generates optimal battery replacement information for the swapping station. This avoids overcharging and wasted energy from vehicles with recovery capabilities. It also determines recommended replacement capacities for vehicles without recovery.

An energy storage system for electric vehicles that allows temporary addition of batteries to extend range. The vehicle has a permanently-installed energy storage system for normal use. But it also has a removable battery compartment that can be manually inserted/removed from the vehicle to add temporary batteries for longer trips. The battery compartment accommodates an extra battery with the same electrical connections and cooling as the permanent system. The removable battery can be installed using a simple horizontal movement, and tools with wheels or adjustable height can help.

Efficiently managing replaceable batteries in electric vehicles using a networked system. The system involves an electronic tag on the battery, a tag terminal at charging stations, a battery monitoring unit in the vehicle, a driver terminal, and a central server. The tag records battery info. The terminal reads/corrects the tag when swapping. The monitor communicates with the tag. The driver app accesses monitor data. The server manages battery info like usage, charge, manufacturer, capacity, etc. It determines replacement costs based on this data.
